Subject:	SGP/MWR/C1 - Spikes in ambient temperature readings
DataStreams:	sgpmwrlosC1.b1, sgpmwrtipC1.a1
Description:	There are intermittent spikes in the Tkair temperature (T ~ 400 K). On 7/28 the sensor was cleaned and the instrument power cycled following a power outage. Readings came back to normal.
Measurements:	sgpmwrtipC1.a1: Ambient temperature(tkair) sgpmwrlosC1.b1: Ambient temperature(tkair)

Subject:	SGP/MWR/C1/E14 - Freezing rain-Incorrect rain flag
DataStreams:	sgpmwrlosC1.b1, sgpmwrlosE14.b1, sgpmwrtipC1.a1, sgpmwrtipE14.a1
Description:	Between 01/12 and 01/15 brightness temperatures show high values (Tb > 100 K) indicative of rain, however the wet_window flag is 0 (indicative of no rain). During that time there where freezing conditions with ice pellets that were not detected by the sensor. The high brightness temperatures may be due to melting ice on the window.
Measurements:	sgpmwrtipC1.a1: Water on Teflon window (1=WET, 0=DRY)(wet_window) sgpmwrlosC1.b1: Water on Teflon window (1=WET, 0=DRY)(wet_window) sgpmwrtipE14.a1: Water on Teflon window (1=WET, 0=DRY)(wet_window) sgpmwrlosE14.b1: Water on Teflon window (1=WET, 0=DRY)(wet_window)

Subject:	SGP/MWR/C1 - Increased noise in 31.4 GHz channel
DataStreams:	sgpmwrlosC1.b1, sgpmwrtipC1.a1
Description:	The 31.4 GHz channel has been showing an increased level of noise which results in increased noise in the LWP retrievals. The instrument is tipping and all other parameters seem to be in the range. The elevate noise started in May, but it seems to have become slightly worse after summer. After November the noise level seems to have gone back to normal.
Measurements:	sgpmwrtipC1.a1: 31.4 GHz sky brightness temperature derived from tip curve(tbsky31tip) Total liquid water along zenith path using tip-derived brightness temperatures(liqtip) sgpmwrlosC1.b1: Sky brightness temperature at 31.4 GHz(tbsky31) Averaged total liquid water along LOS path(liq)
