TWP/GNDRAD/C1 - PIR and IRT: surface temperature comparison
DataStreams:twpgndrad60sC1.b1, twpgndrad60sC1.a1, twpgndrad20sC1.a1
Description:
The GNDRAD continues to look nominally OK. The daily average irradiances
are about what is expected. The comparison of the downward facing IRT and
the calculated brightness temperature from the downward facing PIR show
agreement within and average of about 0.5O C. About 19981206, the daily
average agreement suddenly seems to have gotten better. We should note
to monitor this in the next data package.
