WU baro pressure is not same as my weather station
« on: July 03, 2014, 05:15:19 PM »
WeatherLink sight shows all readings exact as my station but WU baro pressure shows a higher reading even immediately after an update. Should I reinstall the WU software for WeatherLink? Thanks

http://www.wunderground.com/cgi-bin/findweather/getForecast?query=10306&MR=1   This site shows correct pressure of 29.86
http://www.wunderground.com/personal-weather-station/dashboard?ID=KNYNEWYo103 This site shows 29.90

So it seems personal weather station dashboard is not correct. Just went to the graphs and the graph shows the correct baro presssure. So for some reason the digital readout is off. Weird!!

could WU be compensating for  the elevation. I mean that the elevation of your station and the elevation that WU is using might be different?  Then their calculations would be spitting out the data in error?

I thought of that bt Im pretty sure I set both WU and my station to 74 feet. Ill double check but the graphed reading shows the correct pressure?????   No just checked. All say 74 feet elevation!!!

then perhaps the best answer would be to contact WU directly and ask them to explain .   I know they change things from time to time. My readings are fine, but one never can be sure.
