Subject:	SGP/MWR/B1 - Noisy data
DataStreams:	sgpmwrlosB1.b1, sgpmwrtipB1.a1
Description:	After the instrument was returned to service, the brightness temperature data came up extremely noisy. Disregard brightness temperature data as well as PWV and LWP retrievals collected during the indicated time.
Suggestions:
Measurements:	sgpmwrtipB1.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) 31.8 GHz sky brightness temperature derived from tip curve(tbskytip31) 23.8 GHz sky brightness temperature derived from tip curve(tbskytip23) more sgpmwrlosB1.b1: Mean 23.8 GHz sky brightness temperature(tbsky23) Mean 31.4 GHz sky brightness temperature(tbsky31) Total water vapor along LOS path(vap) Averaged total liquid water along LOS path(liq) more
