Subject:
SGP/MFRSR/C1 - Irradiances too high
DataStreams:sgpmfrsrC1.b1, sgpmfrsrC1.a0
Description:
After the A/D convertor lock-up was corrected on 981014, the irradiances as measured by 
the MFRSR were about 20% too high.  981018 is a particular egregious example of measured 
irradiances that are too large. Cause of the problem is not known, though suspect some 
moisture got into the instrument (this was a period of much precipitation).  After 981024, 
the MFRSR settled down and the irradiances returned to a normal range.
