In WeatherLink (with the Bulletin turned off), there is a tab 'Set-Up'> 'Set Barometer'. This is where the Station Elevation correction value is set. In the latest software WL5.6Beta, this value has to be entered in units of 'meters', not 'feet'. Is it possible you entered 1948 meters station elevation, (should be 594 meters?). It seems possible that could generate the error you are seeing.

Turns out my PC system clock is a little fast, and gains a couple of minutes per week. By default, Windows XP updates the System Clock once per week by polling an Internet timeserver, so long as this option is selected: Start > Settings > Control Panel > Date and Time >Internet Time Checkbox: Automatically synchronize with an Internet time server I found this handy tip to change the Internet update interval frequency: ************************************************************** http://www.pcsupportforums.com/archive/index.php/t-193.html "Windows XP updates your system clock via the internet (provided you are connected of course) every 7 days. If you want your clock updated more often, change the interval time like this: Press win key+R and type regedit, then press enter. Navigate to HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Services \W32Time\TimeProviders\NtpClient Select "SpecialPollInterval" Change decimal value from 604800 (7 days) to whatever interval you want in seconds. for example: 172800 (2 days) or 86400 (1 day). Save and exit. - Alan" *************************************************************** Reboot, and the "Date and Time", "Internet Time" tab should display the new values of when the next scheduled synchronization will occur. My clock now stays in sync, and this solved most of my APRS upload problems; thought I would share the information.

MT airmasses are characterized by high dew points, typically mid 60's to low 70's F, which is what your adjacent stations have been reporting. I am sure you are correct when you say other area stations receive more rainfall than Middletown due to orographic (mountain) influences, but dew point measurements are not exactly the same thing as high high dew points don't always mean high precip and low dew points don't always mean low precip. Fact is CW1500 and KOKV have just about the same elevation above sea level as your station (e.g. low 700 ft). Rooftop siting will influence your temperature measurements, as it is possible the tar shingles will had to the ambient air temperature during summer afternoons. This is why it is suggested that temperature and humidity measurements be made at 5 ft above ground level on a "natural" and representative ground cover (grass, if grass is typical for your area; not concrete other man-made surfaces). In almost all cases, the temperature and humidity sensors are on the same circuit board and must be co-located. Humidity measurements will not suffer terribly from a non-standard vertical siting of 10, 15, 20, or 25 ft above ground as humidity, in a well mixed atmosphere, does not change dramatically with elevation over the short distances we are talking about. However, artificial sources of moisture like sprinkler systems can add very localized and unrepresentative moisture to the air you are sampling and cause a humidity measurement to be too high. Both Philip and I have small ponds near our humidity sensors (me: neighbor's standard sized pool about 10 ft north, Philip: frog pond a few feet away from his humidity sensor). We have pretty much concluded that these relatively small water sources do not add enough water vapor to the air to make a difference in our day to day humidity measurements. However, I have seen some really violent daytime failures of some dew point sensors, typically those that are not shielded from the sun. In this failure mode, the dew point/humidity drops dramatically during the daylight hours and recovers at night. The predominant problem with humidity measurements is one of calibration, typically they run too high, but sometimes too low, as I suspect your humidity sensor is doing. I suggest doing nothing right now, lets just watch the measurements for a few weeks to get a better idea of your sensor's performance under a variety of moisture ranges (one day we WILL see a nice cold front). Your measurement are really not too fat off from the analysis in most cases at any rate. Hope this helps, Dave Jim Wahler wrote: >Hi Dave, > >It's not a vary good comparison.

As you not, there are occassional "false positive" flags as the buddy and temporal continuity checks will not identify small scale and/or rapidly changing weather events, as you noted. We encourage folks to look at their statistical trends over weeks and months rather than hours and days. In other words, don't worry about the little (short term) stuff and the trend is your friend as they say in the weather biz.

I've been meaning to ask about this for a while. It seems that during the warmer months I will be getting lots of Weather Quality error reports but I assume things will settle down during the cooler months of the year. Only been at this since early spring and have only lived here since January so will have to wait and see, but thought I'd check to see if it is anything to be concerned about. We are very close to the ocean beach, about 800 feet, and frequently on warmer days will get what I am assuming is a Sea Breeze effect: wind will change or increase from the west and will get a rapid, fairly large temp decrease. I've gotten so I can predict accurately whether I'll get the email filled w/ errors :) I have looked at the graphs for another station, CW0799, that is similarly situated, just down the coast from me. They seem to follow mine fairly closely, usually. But, even that short distance away things can be very different on the immediate coast and sometimes we don't track so well. Other stations up the coast are a bit further inland (it doesn't take much!) so not always a good comparison. Anyhoo, I've watched my Temp error and std dev get larger and larger and am just concerned that at some point it will be considered bad enough to throw out the data. The nearest METAR station is KHQM and they are inland on the harbor - conditions are MUCH different there. Should I be concerned? Is there anything I should do? I believe my data is good, just doesn't agree with the surrounding stations since there really aren't that many located on the beach (or within spitting distance.) Sorry this is getting so long, but I've got a question re: my pressure data. That has consistently been reading slightly high. Very small error but very consistent. Does it appear that maybe some calibration adjustment is in order? I raised the anemometer since we have shore pine around the property and was getting some attenuation from those. Now the anemometer is about 30 feet up and slightly higher than most of the tips of the branches. Have noticed the error moving toward zero steadily but there is still a pretty good std. dev. I'm not a statistics person (lots of math background but never got into stats stuff unfortunately), so not sure exactly how to interpret that. Well, didn't mean to write a book here. Sorry for the length, just been saving all this up. Any insight or direction where to go (I know, I know..) to learn more about any of the above is very welcome.

That seabreeze is always going to keep you cooler in the summertime, just as in the winter you'll be warmer than surrounding inland locations. One idea would be to monitor your temp when you get an off shore wind. That would give you a better idea how your data matches up with inland locations being that all surrounding locations are experiencing the same breeze as opposed to the cool seabreeze being modified by the warmer land mass. As for the pressure reading see if there is a buoy near you. Sorry I don't have a link to the site. Wait until you have a steady barometer and check several buoy locations. I would think you could find a common pressure reading you could be happy with. Over all beach location weather is going to differ from inland locations. I really don't think there is much you can do in regards to data quality errors because of your location. I certainly wouldn't change too much unless you feel you readings are inaccurate. Just my two cents. Maybe someone else has a solution. Dave.

You have your station set to post on a one-minute interval, and that places the highest possible demand on the transmitter battery. Lithium batteries are only good for about 300-500 charge discharge cycles, and develop a series resistance over time. At 1-min transmit interval, yours gets the smallest possible chance to recharge, and my guess is that it stays undercharged. I think CWOP MesoNet only uses one data packet every 15 mins, so you might consider increasing your data interval to 5, 10, or 15 min to conserve transmitter battery power and extend the battery life. Davis says the lithium battery is good for 8 mo (without sunlight) up to 2 years, but they don't say at what transmit interval that rating is measured. Radio Shack has a $15.50 battery checker that will test 3V Lithium batteries under a 1mA load. Catalog #: 22-080. Davis instructions says to point the solar cell to the South in the Northern Hemisphere. That sense to me for the winter months and continuous daylight charging. There is an AC power jack input on my wireless VP2 transmitter, but I couldn't find any Davis accessories to hard wire it, nor any reference to the use of that. You might quiz Davis about it. If the battery is not the problem, check the console diagnostic screens detailed in the console manual. That data will get you some clues about the reception problem, and will tell you if the station console battery is low. The problem can be in the receiver as well as the transmitter. The VP2 has option to increase the transmitter gain, I do not know if you have that option not on a VP. VP2 transmits within 902 to 928 Mhz FHSS. I have 900Mhz phones that a microwave interferes with, but the VP2 spread spectrum seems to have good immunity from RF sources and interference. Try changing your station ID switches to a different setting if you think there is some local source interfering with the transmissions. Check your antenna orientations too; both vertical if at the same height, and with as few obstructions between them as possible.

There could be interference with that or a wireless router. A strong field nearby can "swamp" out a receiver, such as a small transmitter, or a very dangerous item like a crappy microwave. It could also be one of your neighbors has set up something that is interfering, or even a wireless service in your neighborhood. It would be really nice if Davis sold little directional antennas that you could replace the omni-directional that is included, and having another directional on the console would double or more the distance you could go depending on the antenna design. -Mark _____ From: wxqc-bounces@lists.gladstonefamily.net [mailto:wxqc-bounces@lists.gladstonefamily.net] On Behalf Of Steve Schlei Sent: Monday, August 15, 2005 11:07 AM To: wxqc@lists.gladstonefamily.net Subject: [wxqc] Wireless Vantage Pro transmission drops Over the past two days my Vantage Pro Wireless station either hasn't transmitted packets or my receiver isn't receiving packets at sporadic intervals.

However, as I said before, it appears the luthium battery is under charged. It could be due to insufficient sunlight striking the solar panel or just a bad battery. I realize Davis recommends orienting the solar panel to the south, but, in my location, with the summer sun rising in the NE & setting in the WNW, the rain collector shields the solar panel from direct sunlight. Granted, it took over a year for my lithium battery to go to low voltage under those conditions but since I aimed the solar panel west, I haven't had any problems. My outside unit sits in an open area with the closest shading structure 200' away. However, if one is located where there are lots of trees & structures close by, it could severely restrict the amount of sunlight available to keep the battery charged.

So far, my temperature data is not meeting the CWOP quality goals determined by comparing my measures with predicted values for my location. The neighborhood we live in has many tall oak trees and our yard backs up to a wooded forest preserve area. I situated the Davis temperature and humidity sensors on a 5? post approximately 50 feet from the edge of the wooded area and about 35? from our house. The anemometer is attached to a tv antenna mast on our roof about 30? feet up. Presently this site is in full sunlight from approximately 10 AM to about 3:30 PM. In the morning hours the site is shaded by our house and in the afternoon it is shaded by the woods. Our temperature readings are consistently below the predicted values with a noticeably bigger difference that often occurs beginning around 12 noon local time. However the nearest other reporting site (1 ? miles away), DuPage Airport, reports temperature that follow our readings noticeably closer than the predicted values. How are the predicted data in the analysis calculated? And are my readings possibly more accurate due to the use of an aspirated temperature shield vs. nearby stations using non-aspirated shields which may tend to maintain more heat as the day goes on? Or am I simply being affected adversely by the proximity of the wooded area. But if that be the case, why is DuPage closer to my readings than to the predicted readings? I am curious about how one assesses the quality of a temperature reading in general. If one measures temperature in an area where there are numerous trees, is this reading any less accurate than one taken in area without trees? Here are links for several days to our data and analyses: http://weather.gladstonefamily.net/qchart/C4066?date=20050817 &addnl=KDPA&Add+to+charts=Add+to+charts&.cgifields=addnl http://weather.gladstonefamily.net/qchart/C4066?date=20050816 &addnl=KDPA&Add+to+charts=Add+to+charts&.cgifields=addnl http://weather.gladstonefamily.net/qchart/C4066?date=20050815 &addnl=KDPA&Add+to+charts=Add+to+charts&.cgifields=addnl http://weather.gladstonefamily.net/qchart/C4066?date=20050814 &addnl=KDPA&Add+to+charts=Add+to+charts&.cgifields=addnl http://weather.gladstonefamily.net/qchart/C4066?date=20050813 &addnl=KDPA&Add+to+charts=Add+to+charts&.cgifields=addnl I?m sure there?s a lot that I don?t understand about what is happening here so I will appreciate any help and suggestions to improve both the quality of data that I am providing and my understanding of the science. -------------- next part -------------- An HTML attachment was scrubbed...

Russ references a study made by Gearld Gill (e.g. the "Gill" shield) that documented elevated temps in passively aspirated shields here: http://www.wxqa.com/shields.html The other issue you picked up on is the proximity to the trees. Its been dry in your area, http://www.drought.unl.edu/dm/monitor.html, and outside of the tree canopy, the soil is getting baked dry and holding more and more summer heat. However in your local area, the combination of shade and resulting moderated soil temperatures help moderate your local temperatures. We also see situations where stations in the outter ring of city suburban regions appear to be (are in fact) cooler than stations closer to the city heat islands (this is the case with my station with corn fields to my north and the DC metro concrete jungle to my south). So in my opinion, you are very accurately measuring temperature for your local area. This is exactly the type of micro-climate we want to characterize with very dense CWOP station network. I know the MADIS QCMS statistics show your station as having mean temperature too cool, but I believe your "cool" bias is real so I would not be concerned about the difference. As your area gets stronger winds and lower sun angles with the advance of the fall season, your cool bias will be reduced and you will get a "green check". For not knowing much, you seem to have figured out great deal!

Russ references a study made by Gearld Gill (e.g. the "Gill" shield) that documented elevated temps in passively aspirated shields here: http://www.wxqa.com/shields.html The other issue you picked up on is the proximity to the trees. Its been dry in your area, http://www.drought.unl.edu/dm/monitor.html, and outside of the tree canopy, the soil is getting baked dry and holding more and more summer heat. However in your local area, the combination of shade and resulting moderated soil temperatures help moderate your local temperatures. We also see situations where stations in the outter ring of city suburban regions appear to be (are in fact) cooler than stations closer to the city heat islands (this is the case with my station with corn fields to my north and the DC metro concrete jungle to my south). So in my opinion, you are very accurately measuring temperature for your local area. This is exactly the type of micro-climate we want to characterize with very dense CWOP station network. I know the MADIS QCMS statistics show your station as having mean temperature too cool, but I believe your "cool" bias is real so I would not be concerned about the difference. As your area gets stronger winds and lower sun angles with the advance of the fall season, your cool bias will be reduced and you will get a "green check". For not knowing much, you seem to have figured out great deal!

So far, my temperature data is not meeting the CWOP quality goals determined by comparing my measures with predicted values for my location. The neighborhood we live in has many tall oak trees and our yard backs up to a wooded forest preserve area. I situated the Davis temperature and humidity sensors on a 5? post approximately 50 feet from the edge of the wooded area and about 35? from our house. The anemometer is attached to a tv antenna mast on our roof about 30? feet up. Presently this site is in full sunlight from approximately 10 AM to about 3:30 PM. In the morning hours the site is shaded by our house and in the afternoon it is shaded by the woods. Our temperature readings are consistently below the predicted values with a noticeably bigger difference that often occurs beginning around 12 noon local time. However the nearest other reporting site (1 ? miles away), DuPage Airport, reports temperature that follow our readings noticeably closer than the predicted values. How are the predicted data in the analysis calculated? And are my readings possibly more accurate due to the use of an aspirated temperature shield vs. nearby stations using non-aspirated shields which may tend to maintain more heat as the day goes on? Or am I simply being affected adversely by the proximity of the wooded area. But if that be the case, why is DuPage closer to my readings than to the predicted readings? I am curious about how one assesses the quality of a temperature reading in general. If one measures temperature in an area where there are numerous trees, is this reading any less accurate than one taken in area without trees?

The closer the ambient temperature gets to 100, the greater the error. The VP2 is mounted about 8 feet off the ground and meets most of the recommended setup for distance from pavement, structures and is located over dirt and grass. My station is about 25feet from the house and over 50 feet from the tall trees. My dew point in the daytime is about 3-5 deghigher than other nearby stations but I usually attribute that to 3 large (> 3/4 acre) ponds in the neighborhood within 500-1000 ft of the VP2. Since I've only had the station a couple of months, I don't have analysis for the colder months...

I have noticed that QC takes this and then corrects it again for temperature. This causes barometer QC for Vantage stations to fluctuate significantly, especially after cold fronts. Can this be programmed in QC? Fact is that Davis Vantage stations do not report altimeter pressure.

Beta 3 is not released. The only difference that I am aware of is a change to the USB driver installer. The application itself is the same as Beta 1.

However, you may have noticed that the new Beta Release alert dialog box that started appearing 8/1 is now blocks the script from functioning. I have modified the script to account for this new WeatherLink startup message. To download the new file, point your browser to this address: http://www.prevelige.com/weather/wlstart.zip and save the file to your desktop. The ZIP file contains two versions of the script. They are identical except that the one named WLStartMin.exe will minimize WeatherLink after opening the Bulletin window.

In WeatherLink (with the Bulletin turned off), there is a tab 'Set-Up'> 'Set Barometer'. This is where the Station Elevation correction value is set. In the latest software WL5.6Beta, this value has to be entered in units of 'meters', not 'feet'. Is it possible you entered 1948 meters station elevation, (should be 594 meters?). It seems possible that could generate the error you are seeing.

Turns out my PC system clock is a little fast, and gains a couple of minutes per week. By default, Windows XP updates the System Clock once per week by polling an Internet timeserver, so long as this option is selected: Start > Settings > Control Panel > Date and Time >Internet Time Checkbox: Automatically synchronize with an Internet time server I found this handy tip to change the Internet update interval frequency: ************************************************************** http://www.pcsupportforums.com/archive/index.php/t-193.html "Windows XP updates your system clock via the internet (provided you are connected of course) every 7 days. If you want your clock updated more often, change the interval time like this: Press win key+R and type regedit, then press enter. Navigate to HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Services \W32Time\TimeProviders\NtpClient Select "SpecialPollInterval" Change decimal value from 604800 (7 days) to whatever interval you want in seconds. for example: 172800 (2 days) or 86400 (1 day). Save and exit. - Alan" *************************************************************** Reboot, and the "Date and Time", "Internet Time" tab should display the new values of when the next scheduled synchronization will occur. My clock now stays in sync, and this solved most of my APRS upload problems; thought I would share the information.

See here in comparison to the Winchester Airport (KOKV) observation: http://weather.gladstonefamily.net/qchart/C3977?date=20050806&addnl=KOKV&Add+to+charts=Add+to+charts&.cgifields=addnl The message says that you need to 7 F degrees to your dew point an that day to bring it up to the humidity of the nearby stations. However, the 7F degree was just a single day's sample. I suspect your are running 3-4F too dry most of the time. Hope this helps, Dave CW0351 P.S. You still need to update your position in your VWSAPRS software so FINDU plots your station in "downtown" Middletown, as per our previous email.

MT airmasses are characterized by high dew points, typically mid 60's to low 70's F, which is what your adjacent stations have been reporting. I am sure you are correct when you say other area stations receive more rainfall than Middletown due to orographic (mountain) influences, but dew point measurements are not exactly the same thing as high high dew points don't always mean high precip and low dew points don't always mean low precip. Fact is CW1500 and KOKV have just about the same elevation above sea level as your station (e.g. low 700 ft). Rooftop siting will influence your temperature measurements, as it is possible the tar shingles will had to the ambient air temperature during summer afternoons. This is why it is suggested that temperature and humidity measurements be made at 5 ft above ground level on a "natural" and representative ground cover (grass, if grass is typical for your area; not concrete other man-made surfaces). In almost all cases, the temperature and humidity sensors are on the same circuit board and must be co-located. Humidity measurements will not suffer terribly from a non-standard vertical siting of 10, 15, 20, or 25 ft above ground as humidity, in a well mixed atmosphere, does not change dramatically with elevation over the short distances we are talking about. However, artificial sources of moisture like sprinkler systems can add very localized and unrepresentative moisture to the air you are sampling and cause a humidity measurement to be too high. Both Philip and I have small ponds near our humidity sensors (me: neighbor's standard sized pool about 10 ft north, Philip: frog pond a few feet away from his humidity sensor). We have pretty much concluded that these relatively small water sources do not add enough water vapor to the air to make a difference in our day to day humidity measurements. However, I have seen some really violent daytime failures of some dew point sensors, typically those that are not shielded from the sun. In this failure mode, the dew point/humidity drops dramatically during the daylight hours and recovers at night. The predominant problem with humidity measurements is one of calibration, typically they run too high, but sometimes too low, as I suspect your humidity sensor is doing. I suggest doing nothing right now, lets just watch the measurements for a few weeks to get a better idea of your sensor's performance under a variety of moisture ranges (one day we WILL see a nice cold front). Your measurement are really not too fat off from the analysis in most cases at any rate. Hope this helps, Dave Jim Wahler wrote: >Hi Dave, > >It's not a vary good comparison.
