SGP/MET/E35 - Temperature/humidity sensor not calibrated annually
DataStreams:sgpmetE35.b1
Description:
The temperature/humidity sensor was not calibrated annually during this time, but passed 
all 6-month field calibration checks. Comparison with a nearby Mesonet site suggests the 
relative humidity may be reading low. An exit calibration will characterize severity when 
the sensor is replaced.

In general, the relative humidity may have been subject to drift during this time. The 
manufacturer characterizes sensor drift at <1% / year.
