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)
