The Lowest humidity I could find here at Hillman, MN was 10% May 4th 2005 at 2:45pm The dewpoint
was 3.4?F Temperature 60.3?F.

My wind speed stopped working at 2:40am this morning. I plugged in my spare anemometer to the ISS
no luck. Powered down the ISS and restarted still no speed. Battery at 3.02 Volts, good. Wind
direction is still working. Has anybody else had this problem and figured out how to get it going
again?

Cobalt blue skies and moderate temps though are extremely welcome after a

Well, apparently I was mistaken about the humidity in the winter, it was
probably an indoors reading that was ridiculously low. However I had a
dewpoint of 0.8F this morning at 7:54AM this morning which is REALLY low for
us this time of year, though the humidity was 15% at the time, which doesn?t
sound as impressive. Not a good day for burning the rubbish outside. It is a
good day for burning off the fields, though I won?t risk it in this weather,
I like to keep that process contained.

Early this afternoon, my station recorded the lowest YTD Relative Humidity
of 14% here in central New England.  The past few days here have seen
extremely low humidity levels and there are brush fire alerts posted.
Cobalt blue skies and moderate temps though are extremely welcome after a
long winter.  Anyone else seeing record lows similar to this?

ISS no luck. Powered down the ISS and restarted still no speed. Battery at 3.02 Volts, good. Wind
direction is still working. I am disappointed I will be missing wind data for the first time. Any
help would be appreciated.

I do not see any reports of transmission problems during those times.

CW5851 is a Davis Vantage Pro with Weather Link 5.7a

Is this a configuration problem on my part or some interaction with 
surrounding stations?

Thanks,
Fred.

This is what you are striving for! The reading lines are only reported 
if there is an error. This is somewhat easier to see in the HTML flavor 
of the email when the error reading gets bolded.

In this case, the three temperature readings are flagged. If this 
happens regularly at this time (which is just after sunset at your 
location), then it means that you are cooling off more rapidly than 
expected. This is probably due to local microclimate effects.

Hi folks,

 

Recently upgraded my VP2 firmware, I am now getting consistent barometer
errors each day. I think I need to make an adjustment, but I am not sure
what the value should be. Could someone make a recommendation?

Ok, thats good news, I'll have to go back over the 2300 UTC errors for 
the last few months and and see if I can
correlate them as you explained. On the error lines I was assuming that 
the "2/96" meant two errors out of 96 recieved.

Thanks,
Fred.

Fred,

The 2/96 does mean that, but the data is somewhat noisy, and if the 
'error' readings are not consecutive in time, then the script assumes 
that there is noise, and doesn't bother to report them. This cleans up 
the clutter significantly. You are then left with periods of time when 
there are continuous 'errors'. These (typically) bear some level of 
investigation.

I too did the latest VP2 wireless update recently and I believe that part of that update improved barometer readings, here is the update info from the Davis support page,
   
  Firmware version 1.6
1. Changed the default console year to 2006.
2. Added barometer filter to smooth out the barometric reading over the hour.
3. Fixed the daylight savings bit to indicate whether daylight saving is on or off in the automatic mode.

  Steve, as132 / kf6wax-3

I notice there is a weatherstation reporting to Weatherunderground in
De Kalb. Is that you? If not, have you compared your data to that
data?

The change Davis made has to do with how the sea level pressure (SLP) is
calculated. Their previous calculation would often show anomalous values the
top of each hour. This was related to how the mean temperature was
calculated (basically an average of the current temperature and the temp 12
hours before). They only stored hourly temperature data, so if there was a
big swing of temperature within the hour 12 hours before, it would cause a
jog in the SLP value when the algorithm switched from one 12 hour ago temp
to the next. This was most noticeable 12 hours after sunrise. It was
suggested to them that they either store and use more granular historical
temp data, or at least extrapolate the 12 hour ago temp so that the true
barometric trend would come through rather than hourly jogs.

 

When you make the firmware update, there is apparently an initial lack of
the extra temp data used in the calculation. So right after updating, the
displayed pressure jogs far from where it should be, and then over the next
12 hours homes back in to where it should be. If you are sending data during
this period, it could mess up your QC rating. If you calibrated your
barometer during that time to "fix" the apparent error, you'll have to
calibrate again to back that change out, because the apparent error fixes
itself within 12 hours.

 

I think the impact of this is relative to elevation. Those close to sea
level wouldn't have noticed the anomaly Davis was fixing, and probably
wouldn't notice the 12 hour issue after updating the firmware which I
described above. But those at elevation, and certainly those above 1000 ft.
likely will.

Subject: [wxqc] Firmware Upgrade & Errors!

 

Hi folks,

 

Recently upgraded my VP2 firmware, I am now getting consistent barometer
errors each day. I think I need to make an adjustment, but I am not sure
what the value should be. Could someone make a recommendation?

I was just curious how this compared to the two official stations in
town. Austin's Camp Mabry reported a high of 81% and a low of 6% this
same day. Austin Bergstrom reported a high of 93% and a low of 8%. My
lowest dew point that day was 8.9F when the temperature was 70.4F.

I recall enjoying the fact that my soda didn't collect any
condensation, either indoors or out. The last time I experienced that
was when I was in El Paso (which is where all the dry air was coming
from).

I think this station is affecting my  dewpoint error. As you can see if you look at AP433 there is a lot of trouble showing up. I have been failing dewpoint for a few days now and it is my closest station.  Can you flag it offline?

Well, apparently I was mistaken about the humidity in the winter, it was
probably an indoors reading that was ridiculously low. However I had a
dewpoint of 0.8F this morning at 7:54AM this morning which is REALLY low for
us this time of year, though the humidity was 15% at the time, which doesn?t
sound as impressive. Not a good day for burning the rubbish outside. It is a
good day for burning off the fields, though I won?t risk it in this weather,
I like to keep that process contained.

Early this afternoon, my station recorded the lowest YTD Relative Humidity
of 14% here in central New England.  The past few days here have seen
extremely low humidity levels and there are brush fire alerts posted.
Cobalt blue skies and moderate temps though are extremely welcome after a
long winter.  Anyone else seeing record lows similar to this?

After you're logged in, you scroll to the bottom of the tabular data list of
the date you want to edit, and there'll be a radio button called "Delete
Specific Entries" Click it, and when the page reloads you'll see each record
has a "delete Entry" link on the right hand side of the record. Click it and
the record is gone.
 
The first time I had to edit Weather Underground, I was cleaning the rain
gauge, and accidentally gave us some rain on a bright & sunny summer
afternoon. I didn't get to the computer in time, so I had to edit Weather
Underground. The second time I was, umm... cleaning the rain gauge again,
but this time I was able to edit the file in Weatherlink before it was
uploaded. After that, I disconnect the rain gauge from the transmitter
before messing with it.

I'd back it up anyway, just in case your data gets toasted, but the times
I've done it, it leaves the executables for the previous versions in the
directory, so you can run an earlier version should you choose to do so.

Sorry for the platform specific question.  I'm upgrading my Weatherlink 5.6a

just in case I need to go back?

After you're logged in, you scroll to the bottom of the tabular data list of
the date you want to edit, and there'll be a radio button called "Delete
Specific Entries" Click it, and when the page reloads you'll see each record
has a "delete Entry" link on the right hand side of the record. Click it and
the record is gone.

 

The first time I had to edit Weather Underground, I was cleaning the rain
gauge, and accidentally gave us some rain on a bright & sunny summer
afternoon. I didn't get to the computer in time, so I had to edit Weather
Underground. The second time I was, umm... cleaning the rain gauge again,
but this time I was able to edit the file in Weatherlink before it was
uploaded. After that, I disconnect the rain gauge from the transmitter
before messing with it.

Well, apparently I was mistaken about the humidity in the winter, it was
probably an indoors reading that was ridiculously low. However I had a
dewpoint of 0.8F this morning at 7:54AM this morning which is REALLY low for
us this time of year, though the humidity was 15% at the time, which doesn?t
sound as impressive. Not a good day for burning the rubbish outside. It is a
good day for burning off the fields, though I won?t risk it in this weather,
I like to keep that process contained.

Message-ID: <12B6821F-CDFB-4F5E-A4C6-9A1A398DB24F@cox.net>

Hello to all,

I have a problem that I am trying to solve with my LaCrosse WS-3610.  
Intermittently, it had been giving wild readings, but now all I can  
get the console to display is inside temperature and barometric  
pressure. All other sensors are inoperative. I am getting 3.5 volts  
across the red and black conductors on the feed wire all the way to  
the outside temperature sensor. I assume the green and yellow wires  
feed back data to the console. No joy either wired or wireless. Any  
ideas as to what could have gone wrong? Until I get things fixed AS  
318 KI4PEQ reporting is offline. If the unit cannot be repaired, I  
have an Oregon Scientific wireless unit on the way so that I can  
resume reports within the next week to ten days.

Regards,
Richard

hello,
did you pay close attention to the power up section, batts in thermo sensor, 
the power to console and wait 15 minutes??
just start over.
Good luck

Relearn Mode (Relearn Tx) ? Allows the WS-3610 to relocate

the outdoor transmitter (for example, after a changing a battery

in the Thermo-Hygro) without the necessity of a complete resetup

of all system components ? Acknowledge with


CONFIRM
.

3.2 Power Supply

Power can be supplied to the Weather Center using batteries or

the AC adapter. In the case that the AC adapter is used, it will

provide all required power to the system if the Base Station and

Thermo-Hygro Sensor are wired directly together.

3.2.1 Use Batteries for Power:

- First insert two Type C alkaline 1.5 V batteries into the

battery compartment of the Thermo-Hygro-Sensor.

- Immediately after, insert three Type AA alkaline 1.5 V

batteries into the battery compartment of the Touch Screen

Base Station.

3.2.2 Use AC Adapter for Power:

- First insert two Type C alkaline 1.5 V batteries into the

battery compartment of the Thermo-Hygro-Sensor.

- Immediately after, connect the AC adapter to the Base

Station, and then plug it into an AC outlet.

- When the AC adapter is used, batteries may also be placed

in the Base Station to serve as a backup power supply if

there is a power outage.

Note: In either case, it is important to observe this order of

succession because the Sensor will send an identification

code that must be received and stored by the Base Station

within the first few minutes of operation.

Edith,

Looks like you might be having poor console reception. Hold down the temp and humidity keys. This
will put the console into diagnostics mode. The position where the outside humidity is displayed
is where you will look for the console percentage of successfully received packets. I am running
99%. If its low this would account for the intermittent bad data. From weatherlink click on the
yellow note pad icon ( Browse the station data ) scroll to the right and look for ISS recept,
hopefully its staying above 90%, if its not relocate he console to a place where the ISS reception
stays above 90%. Hit the done key when your finished with the diagnostics screen. Also electronic
devices can interfere with reception such as a cordless phone in use or a cell phone. The console
will stop receiving packets while the interference is present. The X will stop flashing in the
lower right corner while the interference is occuring.

Good Luck.

Message-ID: <5e5bd5c30704062200i6c38bcbu815834f9292c18ec@mail.gmail.com>

Hello,

I have recently joined the CWOP network (CW7816).

I have a concern over the way the data quality is being analysed for my
location. Today the 6th of April I received an error for a temperature
discrepancy. I saw this coming by watching the graphs and suspected this
might happen. All the stations around me that are part of the Madis network
are located much closer to the water than mine. I live more inland up a
valley, though not too far up. The Duncan, BC / North Cowichan area is known
for having higher temperatures than other surrounding localities when the
weather starts getting warm. In saying that the Victoria International
Airport CYYJ which is much closer to the water than my station and is
the closest reliable source for weather and pressure, reported temperatures
very close to my own. If I had a siting error I would certainly think I
would have exceeded CYYJ's reported temperature by much more than what I
did. Once again we were nearly the same temperature today.

Any comments would be appreciated.

Thank-you,

Darryl

First, is your altitude correct, ~20 meters from NED seems a bit
much...

It looks like you're seeing warmer temps during the afternoon.
Do you have an aspirated radiation shield? And where is the
sensor located? Is it near sources that may store and radiate
heat, such as above your roof or near a hard surface?

Hello,

I thought I had used a fairly strong comparison with another location to
show that my temps were not out of line to blame it on radiant heat. While
my station is new and it might be possible on a bright hot sunny day to get
some radiant heat at its location I don't think the fact that I was so close
to another reliable source for temperature information that radiant heat
should be the case here. A closer look at one reliable nearby source on that
day, in particular CYYJ should back some of my comments up even though its
in an area like a lot of other stations around me, where its temperatures
are usually cooler than where my station is situated. What I do believe is
happening is that given the location of the other stations around me (most
being near the ocean) I am analysed in relation to them which would not be
an accurate comparison a good part of the time. If I am missing something on
my understanding of how the analysis works I would be more than happy to
hear it, but at this point I think I am making a valid point.

I know by how the graphs appear that radiant heat, given the time of day
things are going out of wack could be a contributing factor, but in this
case I don't believe so. I am too close to CYYJ's temperature and have lived
in this area for over 10 years so I have some idea how the local weather
works around here. I also worked in a profession where I had to have a very
good understanding of the weather everyday I went to work.

If someone has the time to look at all the numbers for my location and the
surrounding stations and give some feedback it would be appreciated. CYYJ
would be the first choice followed by CYCD and then any others you can
locate around me.

I have recently sent an e-mail in to have my height adjusted to 72 meters.

Thanks for your feedback,

Darryl

Is there an accepted protocol determining the predominant wind direction by
averaging?   I've converted wind directions from text to degrees using the
basic format
N     0

NNE   23

NE    45

ENE   68

E     90

ESE   113

SE    135

SSE   158

S     180

SSW   203

SW    225

WSW   248

W     270

WNW   293

NW    315

NNW   338

 

but I'm thinking that averaging is going to weight things.

 

Thanks,

Norm

I'm not sure what an average wind direction even means. There are
probably many approaches to averaging wind direction. One would be to
imagine a line being drawn from an origin. The line is drawn one unit
in the direction of the wind for each time interval. The first line is
drawn from the origin. The next is drawn from the endpoint of that
line, etc. The average direction is then the direction of the overall
line from the origin.

Of course, this is not well defined. Consider if the wind direction
changed one degree every minute for 6 hours, in the same direction
each time. What you'd end up with is a polygon with 360 sides ending
up at the origin. Since it's at the origin, there is no direction.

Another approach would be to think of the directions as baskets on
corners of a 16-pointed scale. Each time you measure wind in a certain
direction, add an item to that basket. The average would then be the
direction the scale pointed, which would be the direction of the
center of gravity of the baskets.

But I'm not so sure average direction is even meaningful, except on
the short term, where it's relatively consistent. Then you can use a
simple average. In this case, what I do is add 180 degrees mod 360 if
the number is close to 0 or 360, then subtract 180 degrees again mod
360 after performing the average.

To determine average wind direction without having the 0 to 360 cross over 
problem, winds are broken down to their U (east/west) and V (north/south) 
components with the origin being in the center at calm. This ensures proper 
averaging irrespect to the arbitrary numeric values assigned in the compass.

For example, a due west wind of X mph would have a 100% positive U value of 
X and 0 for V; north would be 0,-X; east would be -X,0; and south wind would 
be 0,X. Other wind directions would be broken down into U and V using proper 
trigonometry.

That is one way to do it. I use something I find simpler to prevent  
the 360 problem. With each incoming value, I vector add the new value  
with a weight of 1/n. The first reading starts the average, the  
second moves the average 1/2 of the way towards the new reading, the  
third reading moved the average 1/3 of the way towards that new  
reading, the fourth moves the average 1/4 of the way to that new  
reading, and so on. In this way there is only one accumulated vector  
and it is always ready for output, nice when running the averaging  
and output routines as separate processes.

That would work if you're computing the average since a constant time
(like since midnight maybe?) but it wouldn't work for a running
average, like average over the last hour.

For moving averages it would work the same way the other must, which  
is to keep a list of all the readings. You then either recompute the  
average from the full list, or remove the oldest and add the newest  
(both with a weight of 1/n) to the running total. You can't do a  
moving average without keeping all the individual readings.

I don't average wind direction.. I capture it based on the last recorded direction.

Conversion between degrees and text looks like so (assumes 16 points of granularity):

Private Function ConvertDirection(ByVal dDegrees As Single) As String
Select Case dDegrees
Case 0
ConvertDirection = "N"
Case 22.5
ConvertDirection = "NNE"
Case 45
ConvertDirection = "NE"
Case 67.5
ConvertDirection = "ENE"
Case 90
ConvertDirection = "E"
Case 112.5
ConvertDirection = "ESE"
Case 135
ConvertDirection = "SE"
Case 157.5
ConvertDirection = "SSE"
Case 180
ConvertDirection = "S"
Case 202.5
ConvertDirection = "SSW"
Case 225
ConvertDirection = "SW"
Case 247.5
ConvertDirection = "WSW"
Case 270
ConvertDirection = "W"
Case 292.5
ConvertDirection = "WNW"
Case 315
ConvertDirection = "NW"
Case 337.5
ConvertDirection = "NNW"
Case Else
ConvertDirection = dDegrees.ToString
End Select
End Function

For converting degrees to text, I like the following:

http://www.tnetweather.com/nb-0002.php

 

which is basically a two line function

$windlabel = array ("N","NNE", "NE", "ENE", "E", "ESE", "SE", "SSE", "S",

   "SSW","SW", "WSW", "W", "WNN", "NW", "NNW");

$dir = $windlabel[ fmod((($winddir + 11) / 22.5),16) ];

 

For finding average wind direction, I think the accepted method, as
mentioned by others here, is to calculate a vector average. I have seen both
unit vector averages (where wind speed is not considered), and weighted
vector averages (where speed is considered) used by the NOAA/NWS, depending
upon the application. 

http://www.ndbc.noaa.gov/wndav.shtml

 

But I have not been able to find out which of the two is the NWS standard
for observation. This was discussed in a thread last year.

Gee, that looks more complicated than mine:

function Deg2Card($degrees)
{
  $cardinal = array('N','NNE', 'NE',
'ENE','E','ESE','SE','SSE','S','SSW','SW','WSW','W','WNW','NW','NNW','
N');

  return $cardinal[round(($degrees / 22.5), 0)];
}

I guess this discussion has raised another issue that I will have to address
(which is, how are the quarter hour directions determined?  But I'm going to
push forward on my original question right now).  So, I've used a macro to
change the text to degrees using the format I mentioned

I have this data going back to 2000 in Excel spreadsheets and I'm interested
in determining the predominant wind direction for each month and each year
at our site.  I'm not necessarily interested in a running predominant
direction, just historical information.  

I initially just averaged the data per month and per year.  Out of
curiosity, for N, I substituted 360 for 0 and got completely different (not
surprisingly now that I think about it) monthly and yearly "average wind
directions."  This told me I was not doing something right but I thought
there must be a way that historical predominant wind direction is
determined.  Assuming that each year's spreadsheet has about 35000 rows of
readings, I'm hoping to not have to do a lot of actual manipulation of the
data.  I could always sort the data by "text" wind direction without
converting it, then sort it by date and count how many rows per month and
per year there is for each direction but I was hoping there would be a less
labor-intensive way.  I'm particularly interested in a macro if anyone has
one or any suggestions.

Thanks,
Norm

One way would be to take a count of each direction and divide that by total number of samples to get a percentage value.

I have this data going back to 2000 in Excel spreadsheets and I'm interested
in determining the predominant wind direction for each month and each year
at our site.  I'm not necessarily interested in a running predominant
direction, just historical information.  

I initially just averaged the data per month and per year.  Out of
curiosity, for N, I substituted 360 for 0 and got completely different (not
surprisingly now that I think about it) monthly and yearly "average wind
directions."  This told me I was not doing something right but I thought
there must be a way that historical predominant wind direction is
determined.  Assuming that each year's spreadsheet has about 35000 rows of
readings, I'm hoping to not have to do a lot of actual manipulation of the
data.  I could always sort the data by "text" wind direction without
converting it, then sort it by date and count how many rows per month and
per year there is for each direction but I was hoping there would be a less
labor-intensive way.  I'm particularly interested in a macro if anyone has
one or any suggestions.

Thanks,
Norm

Gee, that looks more complicated than mine:

function Deg2Card($degrees)
{
  $cardinal = array('N','NNE', 'NE',

  return $cardinal[round(($degrees / 22.5), 0)]; }

Yes, yours is more straightforward. I think he chose fmod so his function
would handle any positive degree value such as 450 degrees without
referencing a non-existent array element. If you know your range is limited
to 0-360 then you can simply add the extra "N" to the array as you've done.
This thread was where that function evolved:
http://www.weather-watch.com/smf/index.php/topic,18983.0.html

As for why I suggested the +11 to him instead of Round, my own code for this
is object pascal, and for performance I used all integer arithmetic wherever
possible as it was at one time much faster than floating point (although I
don't know if it makes that much difference now). I don't program in PHP so
I have no code for that. The actual code I use, which is the integer
equivalent of Round(value / 22.5) is:

    Result := ((value + 11) * 2) div 45;
    if (Result > 15) then Result := Result mod 16;
    // where Result is the index into the label array 

And converting from the label index to degrees is

    Result := (value * 45) div 2;

If your data comes from a VP2, then the 15 minute direction is (if I
remember correctly) the predominate wind, calculated by having 16 "bins" for
the different cardinal points, and bumping a bin's count each time a wind
sample occurs in that direction. At the end of 15 minutes, the bin with the
most wins. 

This does not give a true average direction. But it might be suitable for
what you're doing. You could tweak it by adding a partial bump to the two
adjacent "bins".

If you want some code to look at that calculates the true vector average,
I'd be happy to send it to you if you send me an email.

This is the 360 degree problem mentioned in two prior posts with  
algorithms to address it. To visualize it, imagine two readings of  
359 degrees and 1 degree. The mathematical average is 180, but that  
clearly is not the correct answer, it is zero (or 360) degrees. This  
is not simply a problem for readings at zero, but for any values  
around the compass you hope to average.

You must solve this by using vector math, either of the two given  
algorithms work. There is no simple (add x or divide by y) solution  
to this problem. I do not use excel for math, but it may well have  
vector functions that would simply implementing one of these algorithms.

You also have to decide if magnitude matters. Do you want one hour of  
east wind to balance one hour of west wind regardless of magnitudes,  
or do you want three hours of east wind at 3 MPH to balance 1 hour of  
west wind at 9 MPH? Your examples don't show magnitudes, but it could  
be essential, some weather stations output 0 degrees when winds are  
calm, others output the last value with a non-zero magnitude. Either  
way, if you do not remove values with zero magnitudes they can skew  
your results (fatally if you have a zero degree type of station).  
Some stations (particularly the old Peet anemometers) need a few MPH  
of wind before they return a valid reading, so magnitudes are  
critical for those as well.

Can-o-worms you opened!

I think excel has a count function, doesn't it? You should not need  
to sort or convert to numeric degrees.

Or, you could just call the National Weather Service and see if they  
can give you this info ;-)

That would be error handling, and after seeing the other function,
I added the error handling line:

  if (!isset($degrees) || $degrees > 360) {return "---";}

That should handle anything short of passing it a string, and
even then fail somewhat gracefully.

No complaint there, I haven't actually tested to see which would
be faster in php. Fact is, I had in mind writing a function to do
this and had half started, but didn't complete it until this
thread came up. My weather program reports the mean wind direction
in degrees, and I never felt that was something the average person
would quickly comprehend. So this thread got me thinking about it
again and finally got me to finish that.
