Subject:	TWP/MWR/C1/C2 - Sun in the field of view
DataStreams:	twpmwrlosC1.b1, twpmwrlosC2.b1, twpmwrtipC1.a1, twpmwrtipC2.a1
Description:	Every day between around noon local time (usually between 1 and 2 AM UTC time) there is an increase in the brightness temperatures due to the sun in the field of view of the radiometer. The effect lasts less than an hour around local noon (usually between 1 and 2 AM UTC time). The effect appears as a smooth increase and decrease in brightness temperature.

Subject:	TWP/MWR/C1 - Rain events not flagged
DataStreams:	twpmwrlosC1.b1, twpmwrtipC1.a1
Description:	On some occasions the rain flag did not flag data during likely rain events. Users should carefully examine the data to ensure that they are not contaminated by rain. Also examine the brightness temperature qc variables.
