Subject:
SGP/MWR/B5 - Mixer temp unstable
DataStreams:sgpmwrlosB5.b1, sgpmwrtipB5.a1
Description:
The radiometer mixer temperature was unstable during this time interval. The instability 
will slightly affect calibration.  On 8/21, the instrument was sent to the vendor for 
repair.

June and July data are suspect, the calibration may be slightly incorrect. August data 
should not be used.
