Subject:	TWP/MWR/C3 - Sun in field of view of radiometer
DataStreams:	twpmwrlosC3.b1, twpmwrtipC3.a1
Description:	Each day around local noon (2-3 AM UTC), there is an increase in the brightness temperature due to the sun being in the field of view of the radiometer.

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.
Measurements:	twpmwrtipC2.a1: 23.8 GHz sky signal(tipsky23) 31.4 GHz sky signal(tipsky31) twpmwrtipC1.a1: Total water vapor along zenith path using tip-derived brightness temperatures(vaptip) Total liquid water along zenith path using tip-derived brightness temperatures(liqtip) 23.8 GHz sky brightness temperature derived from tip curve(tbskytip23) 31.8 GHz sky brightness temperature derived from tip curve(tbskytip31) twpmwrlosC1.b1: Averaged total liquid water along LOS path(liq) 23.8 GHz sky signal(sky23) Sky brightness temperature at 31.4 GHz(tbsky31) 31.4 GHz sky signal(sky31) MWR column precipitable water vapor(vap) Sky brightness temperature at 23.8 GHz(tbsky23) twpmwrlosC2.b1: Sky brightness temperature at 31.4 GHz(tbsky31) 31.4 GHz sky signal(sky31) 23.8 GHz sky signal(sky23) Averaged total liquid water along LOS path(liq) MWR column precipitable water vapor(vap) Sky brightness temperature at 23.8 GHz(tbsky23)
