Subject:
SGP/THWAPS/C1 - THWAPS C1 miscalibrated
DataStreams:sgpthwapsC1.b1, sgpthwapsC1.a1
Description:
Power outages apparently led to the THWAPS HMP233 temperature and RH sensor
being replaced at C1.  The power went out at 0340 on 3/9 was restored at
0635 and went out again at 2025.

The new HMP233 appears to be incorrectly calibrated and all temperature
data since its installation are wrong.  If I am correct about the nature
of the calibration problem, the true average temperature can be recovered
from that recorded by a linear conversion, but I don't think its worth the
trouble.
