Subject:
TWP/SKYRAD/C1 - UVB Data questionable/incorrect due to uncontrolled sensor temperature
DataStreams:twpskyrad60sC1.b1, twpskyrad20sC1.a1
Description:
The UVB was not temperature controlled to 25C as required
to ensure accurate data.  UVB data should ONLY be used after 
checking both the bit_data and twpskyrad20sC1.a1 uvb_temp
or inst_down_uvb_temp.  UVB data where the UVB temperature
was outside the range of 24-26C should not be used.
Suggestions: 
Use all UVB data from Manus with caution, checking the inst_down_uvb_temp info in the 

twpskyrad20sC1.a1 data stream to ensure the temperature was maintained within the valid 
range of 24-26C.
