Subject:	GRW/SKYRAD/M1 - Short direct normal questionable
DataStreams:	grwskyrad20sM1.a0, grwskyrad60sM1.b1
Description:	Starting on 05/08/2010 values of short_direct_normal from the NIP instrument were reading low (up to 50W/m2). This was most apparent during sunny/partly sunny periods. The values spontaneously returned to normal on 5/14 with no Ops intervention. Data system checks after that date revealed no apparent problems with instruments or datalogger. The problem has not recurred. Only the short_direct_normal values during this time period are suspect. If direct normal values are needed they can be re-constructed using the following relationship for each minute of data: down_short_hemisp = short_direct_normal * cos(zenith angle) + down_short_diffuse_hemisp

Subject:	GRW/MFRSR/M1 - Shadowband Misalignment
DataStreams:	grwmfrsrM1.a0, grwmfrsrM1.b1
Description:	A shading problem was first evident on 20100508. It affecte data between 0930 and 1600. On 20100523 an attempt was made to adjust the band that was unsuccessful. The shading issue was shifted to the afternoon. Additional maintenance was performed on 20100525. This mostly resolved the issue, though a minor shading problem was noted between 1500 and 2000 on 20100525. Subsequent days are too cloudy to ascertain any problems. The next day with enough clear stretches to pass judgment was 20100610, when no problem was observed. So, all things considered, this DQR ends on 20100525 at 2000 UTC.

Subject:	GRW/NFOV/M1 - Data over-ranging
DataStreams:	grwnfov2chM1.b1
Description:	The 673nm channel was over-ranging at times around local solar noon, with some measured values either failing the MAX QC limit or reporting as missing (-9999). Data that fail the QC limit, and obviously missing values, should not be used.
