I would appreciate it if someone could tell me what is going on with my station.
I have included the reports below for 01-16-2005 and 01-17-2005. I compared the
barometer readings with OAK, SFO, SJO, and HWD and don't appear to be more than
.02 or .03 inches difference between them most of the time. I know I have a
problem with dewpoint. The humidity is always about 20% higher than everyone
else around me but, don't know if it is a problem with the sensor or where it's
located. Where the wind is concerned, I calibrated the sensor with a compass so
I don't understand why this is showing up in error.
Also, I am at 10 ft. elevation and set my barometer with HWD which is at 46 ft.
elevation. If their barometric pressure is at 30.30 in., should it be the same
for my location or do I need to adjust it differently?
Any help would be appreciated. Thanks.
Harold

Note that times are in UTC. The values displayed are 'Observed (error)'
The error value is 'analysis - observed'. I.e. if your observed value is higher
than the computed value, then the error will be negative. You have to pick out
the reading that is in error. The row with the time of 'Smry' is a daily summary
and the data is 'mean(standard deviation)' for each observation during that
day.
