Subject:	NIM/MWR/M1 - Instrument noise problem/RF interference
DataStreams:	nimmwrM1.00, nimmwrlosM1.b1, nimmwrtipM1.a1
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.

Subject:	NIM/MWR/M1 - Reprocessed: Recalibration to correct for occasional overheating.
DataStreams:	nimmwrlosM1.b1, nimmwrtipM1.a1
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: Radiation, longwave, brightness temperature, 23.8 GHz(tbsky23) 31.4 GHz sky brightness temperature(tbsky31) Total liquid water along LOS path(liq) Total water vapor along LOS path(vap)
