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. There is also evidence of a possible small cold bias
in the temperature data. An exit calibration will characterize severity when the sensor
In general, the relative humidity may have been subject to drift during this time. The
manufacturer characterizes sensor drift at <1% / year.
