TWP/GNDRAD/C1 - PIR and IRT: surface temperature comparison
DataStreams:twpgndrad20sC1.a1, twpgndrad60sC1.a1, twpgndrad60sC1.b1
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.

TWP/SKYRAD/GNDRAD/C1 - PSP: Configuration file problem
DataStreams:twpgndrad60sC1.a1, twpgndrad60sC1.b1, twpskyrad60sC1.a1, twpskyrad60sC1.b1
Description:
The following incorrect calibrations values were input into SKYRAD
and GNDRAD loggers:

This error occured because several calibration coefficients are reported
and the wrong one was used.  The 45-55 degree (solar zenith angle range)
value should be used. At approximately 02 GMT on 19990304, these numbers
were corrected.

TWP/C1 - Incorrect elevation reported in Manus Data
DataStreams:twpsmet60sC1.a1, twpsmet60sC1.b1, twpgndrad20sC1.a1, twpgndrad60sC1.a1, twpgndrad60sC1.b1
Description:
(From Bill Clements) We have been using 6m MSL as the station
elevation of Momote (Manus).  This was based on information
posted near the station barometer in the Momote Weather Service
Office.  It turns out that the official WMO station elevation
for Momote is 4m MSL and the upper air elevation is 5m MSL.

All Manus instruments except the sonde station are at 4m MSL.
The sonde launching station is at 5m MSL.
