Subject:	NSA/MFRSR/C1 - Shadowband misalignment

Description:	There is a minor shading issue at high zenith angles (0530 - 1630 UTC). Due to extremely persistent cloudy conditions, maintenance was not attempted until 20090811. Cloudy conditions persisted, and it was never clear from the data if the instrument was shading properly at high zenith angles. Therefore, the DQR end date is listed as the time maintenance was performed.

Subject:	NSA/MET/C1 - 2m RH values incorrect
DataStreams:	nsametC1.b1, nsatwrC1.b1
Description:	The new t/rh probe installed during annual calibrations and checks began to exhibit readings that were biased high compared to the Chilled Mirror Hygrometer. In high RH conditions the sensor would consistently report RH values in excess of 105%. Comparisons to the other tower levels also suggested that the 2m level RH data is suspect.

Subject:	NSA/QCRAD/C1/C2 - error in qc flags
DataStreams:	nsaqcrad1longC1.c1, nsaqcrad1longC2.c1
Description:	In the qc_down_short_diffuse_hemisp field, QC failures from the test indicated by bit_13, "data failed tracker off test", were set incorrectly as bit_9, "GSW2SumSW (93 > SZA > 75 and SumSW > 50; GSW/SumSW < 0.85 or GSW/SumSW > 1.15)". Solar tracker failures are correctly indicated in the aqc_down_short_diffuse_hemisp field. In the qc_short_direct_normal field, QC failures from the test indicated by bit_10, "data failed tracker off test", were set incorrectly as bit_9, "GSW2SumSW (93 > SZA > 75 and SumSW > 50; GSW/ SumSW < 0.85 or GSW/SumSW > 1.15)". Solar tracker failures are correctly indicated in the aqc_short_direct_normal field. This is a software problem in the VAP that impacts all dates for which a solar tracker failure occurred prior to 20100608 for each facility. The 19990821 start date was chosen because the DQR system can not link multiple start/end date/times with multiple facilities within the same report. As a result, the latest start date corresponding to C2 was chosen. The actual start dates for which this problem could have occurred for each facility are as follows: C1: 19980215 C2: 19990821 Please note that if a solar tracker failure is not indicated by the aqc_down_short_diffuse_hemisp and/or aqc_short_direct_normal fields you can ignore this DQR.
