Subject:	NSA/GNDRAD/C1 - Incorrect calibration coefficients
DataStreams:	nsagndrad20sC1.a0, nsagndrad20sC1.a1, nsagndrad60sC1.b1, nsagndradC1.00
Description:	BarrowC1, Gndrad. On Aug 11th the PSP-US was changed out and the Campbell program was changed to reflect this. However, an old program that uses the 4 coefficient PIR cal factors was used. The PIR-UIR was not changed out, however, the logger program coeffs reverted back to the 4 Coeffcients. The Eppley PIR-UIR coefficients for this S/N 30168F3 are : K0=0.0, K1(aka k)=.25253, K2= 1.0, K3=-4, Kr=0.0.

Subject:	NSA/MFRSR/C1 - Minor shading problem

Description:	There was a very minor shading problem when the instrument resumed banding after solar midnight. This only affected a small portion of each day; not more than two hours after the instrument resumed banding after solar midnight. 7/9 is the best example of the problem. The boundaries of this DQR are a little loose as the often cloudy conditions make it difficult to precisely say when the problem stopped. Maintenance was performed on 9/5, but the problem was not visible sometime before that.

Subject:	NSA/METTWR/C1 - All data from 10m Level Missing
DataStreams:	nsamettwr4hC1.b1
Description:	The winch that lowers the tower booms failed. Manual testing of the motor and winch allowed the booms to be lowered briefly and then raised back into position. A heavy freezing rain/icing event added extra weight to the booms. This extra weight was suspected as the cause as to why the 10m boom became disconnected. After a new motor was installed and all booms were lowered and re-raised the 10m level came back on line.

Subject:	NSA/METTWR/C1 - 40m Wind Direction Data Suspect
DataStreams:	nsamettwr4hC1.b1
Description:	The 40m wind direction data was suspect due to icing on the vane or a failing shafter heater or a combination of both. The affected data can be easily seen on comparison plots with other levels data or by checking the standard deviation of the 40m wind direction. Any standard deviation of less than 0.10 degrees for the 40m level suggest a sluggish/ice affected sensor.
Measurements:	nsamettwr4hC1.b1: 40m Vector Averaged Wind Direction(WD40M_DU_WVT) Standard Deviation of 40m Vector Averaged Wind Direction(WD40M_SDU_WVT)

Subject:	NSA/METTWR/C1 - 20m RH Data Questionable
DataStreams:	nsamettwr4hC1.b1
Description:	The 20m RH data was questionable at times. When the data appeared to be poor was when the 2m and 20m agreed better than the 20m and the 40m and/or 10m.
Measurements:	nsamettwr4hC1.b1: Standard Deviation of 20m Calculated Dew Point(DP20M_STD) Standard Deviation of 20m Calculated Vapor Pressure(VP20M_STD) Standard Deviation of 20m Relative Humidity(RH20M_STD) 20m Average Relative Humidity(RH20M_AVG) 20m Average Calculated Vapor Pressure(VP20M_AVG) 20m Average Calculated Dew Point(DP20M_AVG)
