The part that has failed is the level shifter that interfaces from the RS-232 COM port to the 1-Wire network. Presently AAG doesn't have these in stock for individual sale. So, last night I ordered an entire weather station and the level shifter interface part is included with the entire weather station. Bud Saum, K0GS, who lives in Kiowa, CO, has offered to accompany me to Deer Trail and get the Deer Trail weather station back functioning.

I have a Davis Wizard III, which has no humidity or barometric sensors. I am using Weather Link 5.6, and the WeatherLink Weather Underground Expansion Module, using rapid fire beta. Weather link shows the correct model and data, but virtual weather station show the bogus reading (255% humidity, 19.99in). The help page for Expansion Module makes mention of a bug fix for 255 wind gust bug. 255 is one of those magic numbers.... I've completely cleared the station twice, reinstalled the software with no luck. My only thoughts are, somehow the bogus data got into the Davis Wizard somehow, Virtual Weather station and weather link are somehow co-mingling data, or bad data got sent up to WU, and is now "stuck" in my database on WU. I am going to load a new PC with the software, leaving off the virtual weather station software, and create a new WU account. Anyone have similar issues? Thanks in advance.

Interesting enough, we have found where people have moved across the country and not checked in with us. The result is their QC statistics look really funky, e.g. absolutely uncorrelated to the stations where it used to be located.

CWOP QC statistics have shown numerous cases where the temp sensor has a significant warm bias during maximum solar radiation. The trouble is the surplus "Leggs" cone LaCrosse passes off as a radiation shield (they probably got a great deal for the cones on EBay from my ex-wife who collected them for no particular reason, why knew?). The biggest problem is a lack of ventilation, see here http://www.lacrossetechnology.com/products/pwc/sensors/2315al_thermo.html, so as the cone is heated by the sun, the heat within the cone collects causing temperatures to reported 10-20 degrees above the actual ambient afternoon temperature. The good news is you can build a "home brew" radiation shield which have louvers which supports sampling of the free "ambient" air. I recommend everyone using the stock LaCrosse "cone" on the temperature sensor to visit Russ Chadwick's Radiation Shield page, http://www.wxqa.com/shields.html, and consider replacing it with one of the examples discussed on the page. On a positive note, I'd love to add your weather code to the CWOP Info page, http://www.cwop.info. What "CW" ID are you?

I'd recommend doing a CTRL-ALT-DEL and looking at the task manager to see if VWS is still running, either as an application or a process. Use Task Manager to close it, then try running WeatherLink. Sounds like WeatherLink isn't successfully connecting to your serial port.

Unplug your data logger from the PC and start Weatherlink, under Startup, Internet Settings see how many Profiles are set to start in one minute sessions and either temporarily set them to 5 min or disable all together. Shut down Weatherlink, reconnect your data logger and restart Weatherlink. If it still hangs you most likely have a bad history file for the month of April and will have to rename it so that Weatherlink can create a new data file.

Then you can log into the machine and operate it like it was local. It does open security issues, but keep the password strong. It may take some playing to get this going (it has been a while for me) but it is built into windows. Otherwise try using a program called TightVNC which is a very nice program. Run the server on startup on the remote machine, and use a strong password. Then you can control the box from any machine. http://www.tightvnc.com/ It is excellent for this type of work as well as real work. ;-). You will have to have the machine auto-login and run the VNC server, but you need to be logged-in anyways with the weather software. You shouldn't need to reboot every week unless there is a serious hardware issue. -Mark -----Original Message----- From: wxqc-bounces@lists.gladstonefamily.net [mailto:wxqc-bounces@lists.gladstonefamily.net] On Behalf Of John James Sent: Wednesday, April 05, 2006 4:49 PM To: Discussion of weather data quality issues; Discussion of weather data quality issues Cc: Richard Engle Subject: Re: [wxqc] Weatherlink Upload Both my sites are hung uploading somewhere.

You are off a good bit there. Is your elevation correctly entered into the station? Check the local airport for their barometric reading. I notice you have a lake in close proximity to your house. Not familiar with the area, what is the prevaling wind direction? Are you perhaps picking up humidity from the lake? If that is the case, not much you can do about that, but being that DP is a calculated number, you might want to check the calibration of your humidity sensor too. That has a big part in the dew point calculation, and your humidity appears to be off a rather decent amount too. That would be the first thing I'd check, and see if you can get the humidity closer. DP would follow along with changes to that. You didn't mention what station hardware you are using, so that would be a help in diagnosis too.

I have occasionally been getting error reports indicating my dew point is in error. In order to see if I could determine a better calibration for my system (Peat U2000) I purchased a sling psychrometer and have been running tests periodically for the past two months. What I have discovered is that the humidity sensor is non-linear. Particularly at low humidity readings, although it is also off at high humidity levels also. This information seems to correspond to the days I get the big red X on my QC data. I determined the non-linearity by plotting the data from the psychrometer and from my weather station in an X-Y scatter plot and then applying a trend line to the data (using Excel). The "best fit" provides me an equation of y = -0.0041x2 + 1.6786x - 25.872, where x is the psychrometer data and y is the weather station data. http://pond1.gladstonefamily.net:8080/cgi-bin/wxqchart.pl?site=AP677 Does anyone have any ideas as to how to correct this problem? Is this a common problem with humidity sensors? Thanks Monty Wilson, AP677 jwilson@ncfcomm.com -------------- next part -------------- An HTML attachment was scrubbed...

From rich.taft at att.net Mon Apr 17 00:42:46 2006 From: rich.taft at att.net (rich.taft@att.net) Date: Mon Apr 17 00:42:53 2006 Subject: [wxqc] Barometer Errors Message-ID: <041720060442.8007.44431CC60001151A00001F4721603831169B000E9BD2080C079D@att.net> Yes this is true of VP & VP2 consoles. This issue has been brought to Davis’s attention by many people. Their claim is that the Temp/Humd corrected pressure is "More accurate" then simple elevation correction. My response was "Based on what?" since everyone else is using the elevation only method, then their statement can't be valid. I have been told by Davis tech support that if enough people request that the pressure use the standard correction then it would be implemented in future releases. So unless the NWS is planning on changing the standards I would urge every VP & VP2 owner to contact Davis and ask for the "standardized pressure calculation" On the same note, some of you may know that Davis issued a console firmware upgrade for all wired & wireless VP2 stations (No upgrade is being offered for VP stations) Aside from some bug fixes all this upgrade was to address was the new Daylight savings schedule to start in 2007. Unfortunately anyone who installed the November 28 2005 firmware will find that their Barometer readings will show sporadic spikes and the dew point calculation will be very erratic. I have been told by Davis that this is due to a timing issue between the console and some "third Party" (Read... Not weatherlink) software packages. Davis has removed the Firmware update from their site with a "revisions pending" message. If you have already upgraded your console to the Nov 28 2005 firmware, then there is a Beta (April 5 2006) update available. This beta utilizes the new "No updater required" feature of the Nov 28 firmware, so you will have had to have installed the Nov 28 firmware with an updater, before up grading to the April 5 2006 Firmware. I have installed the Beta and found that it corrected the Dew point & spiky Barom data, but now my Barom is running 1.5 to 2 MB low.

As an example, if your station is at 1246 ft elevation, and we assume a 60% humidity in all cases, then with a mean temperature (avg between temp now and temp 12 hours ago) of 57 F, and a console pressure of 1020.0 mb, the altimeter value you should be sending to CWOP is 1020.0 mb. But at a mean temp of 77 F, a console pressure of 1020.0 mb translates to an altimeter value of 1021.8 mb. In other words, when it was cooler, you would match the nearby stations. But when the temperatures get much warmer, you would be underreporting your pressure by 1.8 mb relative to the nearby stations. You can set your console elevation to zero, and recalibrate your pressure to match a reliable, nearby altimeter. Setting the elevation to zero turns off the sea level reduction calculation that goes on in the console. There are two drawbacks with this though. First, if you have a solar sensor, there are other solar radiation related calculations that go on in the console that need a correct elevation setting to give correct results (a non-issue if you don't have the solar sensor). Second, this method assumes that the offset between sensor pressure and altimeter is a static value at all pressures. This is not the case given the way the altimeter formula works. I don't know offhand whether this would be a significant error for your elevation though.

I thought maybe the problem was the snowmelt, but the last of the snow in yard dissapeared about 2 weeks ago and I am still getting the error message. My thermo-hygrometer is located on the north side of the shed right on the corner (not directly under the eev - the shed is painted white). There are also the two 120 foot spruce trees in the yard. The result is the thermo-hygrometer is not exposed to much direct sunlight. The instrument has its own litte wind and sun shield on it. I think the location is pretty good and combined effect of the all these conditions pretty much amounts to being in a stevenson screen. I am wondering if the problem has to do with my close proximity to Cresent Lake? If you are familiar with Portage la Praire, you know there is an oxbow lake in the centre of town. (It was once part of the Assignaboine River). My weather station is about 100 meters from the water. There are two weather other stations in this area. One, a CWOP station at Southport (also an Enviroment Canada wx station) it is about 5 kms south of Portage and not near any bodies of water. The other is an Enviroment Canada station at the University of Mantoba Field station in the marsh at Delta beach along the shore of Lake Winnipeg about 20 km north of Portage La Praire.

CW5627. It is sitting on my boat dock on Beaver lake about 25' in the air. Its only been operational for about the last month or so. As you can tell from looking at the topo, it is sitting in a pretty good valley. The reason for this placement is I want the windspeed and temperature on the lake. I am also pulling the water temperature based on an extra temp sensor. For me, I have dewpoint errors when there is not much wind. If there is a good steady breeze the dewpoint(humidity) holds quite well with other stations in the area. The Humidity isn't much different up at the house, (about 120 yards up a hill) than it is on the dock. The reason for this is that the whole valley tends to have a higher humidity. Think of the mornings when you are on top of a hill and you look out and see fog sitting in all the valleys around you. We have that occurance pretty regularly in my area, and my house is one of the ones under the fog bank. What I am saying, is to determine if the lake or perhaps your trees holding the moisture near your sensors, watch and see if your errors are worse on days with no wind. That will help you determine if you have a sensor problem or not. Please take what I have said here with a grain of salt as I am new to this weatherstation thing myself. kw ________________________________ From: wxqc-bounces@lists.gladstonefamily.net [mailto:wxqc-bounces@lists.gladstonefamily.net] On Behalf Of Bill Simm Sent: Monday, April 17, 2006 12:35 AM To: wxqc@lists.gladstonefamily.net Subject: [wxqc] dew point errors Hi there, I have been that getting out of range error message regarding my dew point continuously for the last couple of weeks. I thought maybe the problem was the snowmelt, but the last of the snow in yard dissapeared about 2 weeks ago and I am still getting the error message. My thermo-hygrometer is located on the north side of the shed right on the corner (not directly under the eev - the shed is painted white). There are also the two 120 foot spruce trees in the yard. The result is the thermo-hygrometer is not exposed to much direct sunlight. The instrument has its own litte wind and sun shield on it. I think the location is pretty good and combined effect of the all these conditions pretty much amounts to being in a stevenson screen. I am wondering if the problem has to do with my close proximity to Cresent Lake? If you are familiar with Portage la Praire, you know there is an oxbow lake in the centre of town. (It was once part of the Assignaboine River). My weather station is about 100 meters from the water. There are two weather other stations in this area. One, a CWOP station at Southport (also an Enviroment Canada wx station) it is about 5 kms south of Portage and not near any bodies of water. The other is an Enviroment Canada station at the University of Mantoba Field station in the marsh at Delta beach along the shore of Lake Winnipeg about 20 km north of Portage La Praire.

Where I live (I am surrounded by several small lakes), and at night you can see fog move in. Thus the discrepancies. This happens in several spots surrounding the city but not in the city itself, which sits in a valley or by the airport which is 6 miles away, and the cities reporting station. (Our Airport has never reported 100% humidity in the 5 years I have observed the station). Several "ring roads" around the city have signs post saying "Watch for Fog patches". My point is I know that when my sensors hit 98 to 100% humidity they are correct (for my location) as I have a mirror right next to them and can watch Dew form. As soon as the mirror starts to dew over all my sensors indicated 97 to 99. During daylight all are within 5% of each other, and within 5 degrees dew point of surrounding area stations. Fan aspiration does improve the errors in the day to about 2 degrees. And also keeps most of the sensors at 99% in fog. My point is, know your location, and if you sensors are fairly good and new, watch for dew to test the High end, to do the low end you will either have to get a sling or a very good and well calibrated unit. Make sure it's shielded from direct sunlight or use a solar shield with a fan to keep air moving past sensor(s). I replace and / or recalibrate my sensors every three years (or sooner if calibration gets way off).

The tips and info you gave have been very helpful and useful. I should have mention my station Id, it is AS082 and I am in Manitoba Canada. My wxstation is an Oregon Scientific model WMR968. I noticed Tim that in your last quality report you were getting exactly the same dew point error report as myself. I am becoming satisfied there nothing wrong with my sensor, it windy today and I am getting very nearly the same reading those wx stations near me, I am within a degree of them. Its quite clear to me from what you guys have said that local conditions, proximity of water, vegetation and elevation will result in substantial variations from the Madis analysis. In actuality it seems to me that the variations are not really errors but actual microclimate conditions in the immediate area of the sensor. Which is probably useful info in and of itself.

I'm instrumenting a site for some liquified natural gas dispersion experiments, and we are gonna do it tomorrow. I'm putting up a pair of Vaisala WXT-510s, one at 2 meters, one at 10 meters, in as close to an unobstructed area as I can get near the test site ("prop") as possible while staying out of the anticipated plume (if the plume ignites, and the WXT-510s are in it, they'll become molten pieces of thermoplastic slag...). OK, the question: Does anyone have a good idea of the Nyquist frequency for wind measurements? I've got a request for 1-sec measurements to capture all the dynamics. I can do this but suspect the noise will overcome the data and I'll end up having to decimate the data to get a reasonable value. I guess I can look at an FFT in the frequency domain and see if anything drops out on the floor, but that's introducing a lot of work. I seem to recall from the depths of my brain, that wind data should be collected at a rate not greater than once per 30 sec (twice/min), but now I can't find documentation on that. Adding insult to injury, the folks I'm working with on this don't know what sort of continuous data will really aid their analysis. They do know they need to initialize the FEM3A codes they're running with surface met data (temp, pressure, humidity, anemometry) but there's more than a little confusion as to whether it takes continuous data while it's running or if it's an isolated measurement. I'll be looking at data for weeks after this, so there's no real time constraint on answers, if someone's got something!

The wind measurement rate is going to be dependant on the mechanical nature of the sensors. It takes some time for them to accelerate and decelerate. Large wind cups will take a lot longer than say a hot-wire anemometer to respond to a change in wind speed simply due to their mass vs. wind friction. It will also depend on your needs. Weather models may not require sub-30 second measurements but you may require 1 second to determine the volume of air to pass through a certain area in a given time. Probably the fastest response time air measurements will be the ultrasonic variety, which would also be the safest in a combustible environment. They are also mighty expensive. -Mark -----Original Message----- From: wxqc-bounces@lists.gladstonefamily.net [mailto:wxqc-bounces@lists.gladstonefamily.net] On Behalf Of Gerry Creager N5JXS Sent: Wednesday, April 19, 2006 8:29 AM To: Discussion of weather data quality issues Subject: [wxqc] quick question OK, so this is a little off topic, but I'm trying to get a lot of things done quickly and this group tends to have some good expertise...
