Subject:	NIM/MWR/M1 - Instrument noise problem/RF interference
DataStreams:	nimmwrlosM1.b1
Description:	Data are affected by intermittent spikes that become more frequent starting in March 2006. Spikes affect data mostly around 9 AM and 18:00 PM. The origin of the spikes is probably RF interference.
Measurements:	nimmwrlosM1.b1: sky31 23.8 GHz sky brightness temperature(tbsky23) Mean 31.4 GHz sky brightness temperature(tbsky31) Water, liquid, total along line-of-sight path(liq) sky23 Total water vapor along LOS path(vap)

Subject:	NIM/MWR/M1 - Reprocessed: Recalibration to correct for occasional overheating.
DataStreams:	nimmwrlosM1.b1
Description:	The radiometer was intermittently thermally unstable resulting in poor calibrations for four brief time periods. These data have been reprocessed to apply corrected calibrations. The affected time periods were: 20060302-20060303 20060423-20060425 20060512-20060515 20060531-20060603

Subject:	NIM/MWR/M1 - Sun in field of view of radiometer
DataStreams:	nimmwrlosM1.b1
Description:	Around 12 pm every day between 8/1 and 8/31 there is an increase in the brightness temperature due to the sun being in the field of view of the radiometer.
Measurements:	nimmwrlosM1.b1: 23.8 GHz sky brightness temperature(tbsky23) Mean 31.4 GHz sky brightness temperature(tbsky31) Water, liquid, total along line-of-sight path(liq) Total water vapor along LOS path(vap)
