[wxqc] Dewpoints for CW5204 (John & Delta)

Wed Feb 1 15:30:15 EST 2006

I have a Lacrosse WS-2310 station which has the same problem and I
have been trying to figure out what to do. I built a home made shield
and with a constant fan drawing air across the sensors and still have
the problem. 
I don't have any answers yet. You don't want to adjust with the
software I'm told. My the sensor is located 20 feet from the house
mounted on a pole 5 feet off the ground and is located over a grass.
It says to adjust the dew point 3.3 °F higher.

Hi,

   I have a Davis Pro 2 station which I have only had for about 3
weeks now.
The analysis for the last 3 days
http://weather.gladstonefamily.net/site/C5204?tile=10;days=3#Data
shows a
significant mean error in the dewpoint readings.  I have the sensor
set a
good distance from the house mounted on a pole which is attached to a
wooden
post.  The sensor is 5 feet off the ground and located over a grass
area.
It says to adjust the dewpoint down 2.6 degrees but I really don't
want to
do this unless absolutely necessary as it would be masking the real
problem.
Does anyone have any suggestion?

Thanks,

John

Hi All:

Hey... is February 1st, time to start your 2006 climate data
collection 
and processing!

My data logging application does not really do what I want it to do so
I 
developed my own Excel spread sheet and I populate it every month.
Over 
the last several years I have developed a modest station climatology
of 
4 years by borrowing from the Baltimore-Washington Internationals
(BWI) 
station means and using the station's data as a temporary climatology 
baseline (in another 6 years I will have enough statistics to form my 
own station's stats).  I monitor BWI climate data and other area 
stations to see if my data are in the ball-park.

Here are some examples of the Excel files I have developed for 
processing my station's climate data:

CW0351 Station Summary for 2005:
http://mywebpages.comcast.net/brookevilleweather/2005_brookeville-md.x
ls

CW0351 Template file for 2006 monthly climate data:  note I added
daily 
mean max/min temperatures this year
http://mywebpages.comcast.net/brookevilleweather/2006_blank_brookevill
e-md.xls

Feel free to download the Excel templates and modify them for your 
uses.  You can find reference climate data on you local NWS Weather 
Forecast Office web page or go to the National Climate Data Center 
(NCDC) and order the closest COOP station climatology.

Local Climate "Clubs":  I belong to the Washington-Baltimore Climate 
Review (WBCR) which has a 20+ year history of documenting the DC Metro

weather, quite an impressive group run by Brian Smith 
(bgs11111 at erols.com).  Brian compiles data from 200 area stations,
plots 
the data and manually contours the data then snail-mails copies of his

analyzes every month.  I encourage everyone to see if there are any 
local climate groups to participate in!

Regards,

Dave

Dave,
  thanks for the template submission.  I have had my VP2 weather
station for about 10 months now and I have been a little disappointed
in the climate reporting features of the Weatherlink software.  I like
the overall report, but I am disappointed in that it doesn't contain
the mean temp calculation like the NWS office monthly reports do and
that I can't export the report in a tab-delimited format so I don't
have to manually re-type the information into a spreadsheet.
  I think you've inspired me to embark on a climate project for my
station!  Although I've only had my VP2 for 10 months, I've been
maintaining precipitation records for 10 years this July.  Wow, hard
to believe it's been that long!
