[wxqc] Help!!!!!!!

[Hanford R Wright]

Hi
The temp and humidity sensors were just replaced with new ones and the solar
shield cleaned up.  I am using the Peet Bros Ultimeter 2100 weather station
and VWS 12.08p09.  I have a bad wind sensor so I am using a spare at a lower
height untill I can lower my mast down and replace it.  The lake is about
1/2 mile from my house as the crow flies
I don't think it effects me that much.

Hanford,

    Looking at your data, I see a couple of things that might help on
the DP.  First tho, you need to look at the barometer.  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.

    Perhaps some of the other folks can provide some input too.. I did
not look too closely at the surrounding stations to see how they looked,
so it could possibly be some of them out of whack too.

    Hope this helps some.......

Regards,

Sam
