Subject:	NIM/MFRSR/S1 - Shading problem
DataStreams:	nimmfrsrS1.a0, nimmfrsrS1.b1
Description:	A shading problem was first noticed in Aug data. Subsequent careful examination of prior data indicate it may have begun in early July. Because of the near constant dusty conditions, it is difficult to determine exactly when it started. As such a loose start date of 7/1/2006 is given to this DQR. There is reasonable evidence of shading issues in the second half of July. The hours in question are between 1430 and 1700 UTC. Mentor suggests avoiding data during these hours. Maintenance on 10/25 resolved the problem.

Subject:	NIM/SKYRAD/M1 - Tracker inoperative
DataStreams:	nimskyradM1.00, nimskyrad20sM1.a0, nimskyrad60sM1.b1
Description:	Starting on 9/12 the NIM radiometer tracker drifted enough due to sinking supports and a drifting clock that the direct normal measurments (NIP) and the downwelling hemispheric diffuse shortwave measurments (8-48) were adversely affected in the afternoon hours. The shortwave hemispheric global instrument (PSP) and downelling hemispheric longwave shaded1 and shaded2 (PIR) are unaffected by this problem. The tracker problem greatly affected direct measurements and affected the diffuse measurement to a lesser extent. There are no redundant measurements for these instruments. However, during this time range the data collected before local noon (aprox 1140GMT) for all shortwave Skyrad instruments appear to be good.

Subject:	NIM/MFRSR/M1 - Shading problem
DataStreams:	nimmfrsrM1.00, nimmfrsrM1.a0, nimmfrsrM1.b1
Description:	The start time for this shading problem is very loose. Due to the near constant dusty conditions, it is very difficult to ascertain exactly when a shading problem begins. There are subtle hints of it in early to mid Oct, but it isn't until the end of the month when we can say with some certainty that there is a shading issue. Maintenance on 11/27/2006 resolved the problem.

Subject:	NIM/MWRP/M1 - Reprocess: K-band calibration drift
DataStreams:	nimmwrpM1.b1
Description:	During October and November there was a drift in the K-Band calibration of the MWRP. This resulted in brightness temperatures that are too high. New calibration coefficients were derived from the median value of the noise diode temperature for the months of October and November.
