Subject:	NSA/NIMFR/C1 - Serious Alignment/Tracker Problems
DataStreams:	nsanimfrC1.a0, nsanimfrC1.b1
Description:	Late in the evening of April 6, Barrow site had a power failure. When power was restored the tracker went to the wrong position and stopped. The tracker remained in the stopped position until April 19 14:00 when operations was restored. While the Tracker was stopped the NIMFR was pointed some place in space. Head and tube temp remained normal. Detectors were recording no signals or zero sun.

Subject:	NSA/NIMFR/C1 - Failed logger board

Subject:	NSA/NIMFR/C1 - Alignment problem
DataStreams:	nsanimfrC1.a0, nsanimfrC1.b1
Description:	NIMFR at the Barrow Site was not pointing directly at the sun because the solar tracker was not aligned correctly. As a consequence, the measured irradiances are too low. Once the alignment problem was fixed at 6/3/2004 1925 GMT, the problem was apparently solved. The NIP might similarly be affected.

DataStreams:	nsanimfrC1.b1, nsanimfrC1.a0
Description:	The sun does not rise above the horizon at the NSA sites between November and January each year. During this time period, the MFR instruments are removed and returned to PNNL for maintenance and calibration. The instruments are generally re-installed in March.

Subject:	NSA/NIMFR/C1 - Tube heater malfunction
DataStreams:	nsanimfrC1.a0, nsanimfrC1.b1
Description:	The instrument was installed after winter calibration and the tube heater was found to be operating erratically. The purpose of the heating the tube is to keep condensation from forming on the window. Though erratic, the tube temperature was generally warm enough that no condensation should have formed. There was never any evidence of this in the irradiance data. Since it is not believed to have affected the adversely, this DQR is being assigned as transparent.

Subject:	NSA/NIMFR/C1 - Instrument heater not functioning
DataStreams:	nsanimfrC1.b1, nsanimfrC1.a0
Description:	For a short period the instrument heater was not functioning. Do not use data covered by this DQR. Could look at the MFRSR, but it has been experiencing shading issues. This is a very short period of data, so not much is lost.

DataStreams:	nsanimfrC1.a0, nsanimfrC1.b1, nsanimfraod1michC1.c1, nsanimfrlangleyC1.c1
Description:	Near midnight during periods of 24hr (or near 24hr) sun, there are local obstructions that partially to completely block the direct beam, causing a reduction in instrument signal.
