NSA/MFR10m/C2 - Head heater failed
DataStreams:nsamfr10mC2.b1, nsamfr10mC2.00
Description:
When the Atqasuk MFR10m was reinstalled Mar 29 2002,
the head heater failed to operate and the head
temperature followed ambient

April 20 2002, the problem was corrected and the head
temperature is now operating in the normal range

NSA/MFR10M/C2  - Head temp out of tolerance
DataStreams:nsamfr10mC2.00, nsamfr10mC2.b1
Description:
Beginning on 06/03, the 415 nm channel appears to be erratic or noisy at times, which does 
not coincide with the other channels.  Maintenance on 07/02 corrected this problem.

head_temp readings occasionally spike or are erratic, especially between 1500 and 2000 
UTC.  On 06/17, head_temp readings became ambient due to a bad signal cable connection.  
Maintenance on 07/02 ended this problem as well.

Due to the head_temp readings becoming largely out of tolerance, all channel readings 
should be considered questionable, especially after 06/17.

NSA/MFR10M/C1 - Shadowband misaligned
DataStreams:nsamfr10mC1.a0, nsamfr10mC1.b1
Description:
During the period 19980327-19980416, the latitude and longitude entered into the MFR10m 
and used by the instrument software to control shadowband placement was incorrect.  This 
resulted in a slight shading problem.  Users should be aware of the problem and use the 
data during this period with caution.

The internal lat and lon were corrected on 19980416, but the shadowband was not properly 
aligned.  This resulted in a more pronounced shading problem.  The alignment was corrected 
on 19980424.  Data during this period should also be used with caution.

NSA/MFR10M/C1 - Channel 415 noise
DataStreams:nsamfr10mC1.a0, nsamfr10mC1.b1
Description:
There are some very minor downward spikes in the 415 channel that were first noticed in 
the daytime data on 9/7/2006.  They occur throughout Sept and less into Oct/Nov.  The 
instrument was pulled on 11/22 and will be examined over the winter.  The spikes really are 
very minor, and at times only appear as minor bulges when the plot is expanded to a very 
large scale.

NSA/MFR10M/C1 - Instrument rotated skyward to check calibration
DataStreams:nsamfr10mC1.a0, nsamfr10mC1.b1
Description:
For purposes of checking the calibration stability, the GNDMFR at the NSA Barrow was 
turned upside down for two days (19990413-19990414).  So instead of looking at the ground, 
this instrument was pointed toward the zenith. 

When the GNDMFR was turned outside down and compared with the MFRSR data, very good 
agreement between the two data streams was observed.  This indicates that both instruments' 
calibrations are remaining stable.

Subject:
NSA/MFR10M/C1 - Instrument rotated skyward to check calibration
DataStreams:nsamfr10mC1.a0, nsamfr10mC1.b1
Description:
On 19990609 at about 16:10 LST the instrument was flipped upside down so that it was 
pointed directly at the zenith to assess the calibration stability of the both the MFR10m and 
the MFRSR.

This test revealed agreement between the two instruments that ranged from 0.5 to 2.5%, 
depending on the wavelength channel under consideration. The average "error" is 1.5%.  This 
is reasonably good agreement between the two instruments, and there is no evidence of 
gross calibration problems.

The test ended on 19990610 at about 11:30 LST, at which time the MFR10m
was positioned to point towards the ground.
