    I have a Davis Vantage Vue that reads high too when in full sun. Non aspirated, and well over 10 years old, so that may be part of the issue, but has read high for as long as I remember. 

    But regarding aspiration, not a single temp/rh sensor (66 in total) operated by the NJWxNet is aspirated, but they don't have that problem. Aspiration is good, but not essential; perhaps has more to do with sensor design or just a biased sensor.

    What type of equipment do they use at those njwxnet stations if you're familiar?  I assume it's just observers with their own pws.

    Sometimes I match surrounding stations but yes it is in direct sun.

    Problem with alot of the pws with the sun shining on the shield....aspirated is the way to go but they are expensive.

    This why the meso sites can’t be trusted 

    Yeah don't know when it became acceptable to use rooftop stations as official but several in the local mesonets are. Of course we have the problem of improperly sited pws also.

  4. August finished here with a -0.7° temp departure...As for the summer...with June's negative departure and July's positive, the 3 month period finished very close to normal for my station. Rainfall totaled 15.41" which is a bit above normal.
