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 - Incorrect ambient temperature readings
DataStreams:	twpmwrlosC1.b1, twpmwrtipC1.a1
Description:	Starting on 11/21 the ambient temperature readings are intermittent and have spikes. Site operators replaced the dew-blower on 12/11 and readings came back to normal

Subject:	TWP/MWR/C1 - Short periods of wrong ambient temperature
DataStreams:	twpmwrlosC1.b1, twpmwrtipC1.a1
Description:	During this month there are a few intermittent instances of bad ambient temperature readings. I will summarize here these short time ranges: 20080909 between 02:00 and 03:00 UTC 20080909 between 09:00 and 14:00 UTC Additionally the ambient temperature has short but frequent data gaps. The data gaps are very short (less than one hour). Users could interpolate missing data or use alternative sensors such as the surface meteorological data available for the site.
