Subject:	SGP/MFRSR/C1 - Out-of-band filter leakage
DataStreams:	sgpmfrsrC1.a0, sgpmfrsrC1.b1, sgpmfrsrlangleyC1.c1, sgpmfrsrlangplotC1.c1
Description:	Testing of the batch of centrovision filters being used in the MFRSR C1 instrument indicate that the first four filters leak 'out of band' light. The leakage for each filter is (1)415nm 3%, (2)500nm 1-2%, (3)615nm 1-2%, (4)673nm 3%. Acceptable leakage is less than 0.5%. This leakage causes an error in the irradiance values (too high) at these four wavelengths and the optical depths calculated using this data will be too high.

Subject:	SGP/MFR10M/C1 - Data discontinuities
DataStreams:	sgpmfr10mC1.a0, sgpmfr10mC1.b1
Description:	There is a discontinuity in the data (all channels) just after 1500 UTC on June 27, 2003 and again, just before 1930 UTC on Jan 20, 2005. There is nothing unusual in the temp or volt data. At these times the tower was lowered for cleaning so the initial assumption was the instrument was dirty, and a cleaning resulted in the discontinuity. This theory doesn't hold up well though as the tower is lowered for instrument cleaning regularly and these are the only two times in the past few years that a discontinuity coinciding with a lowering of the tower has resulted. Also, down pointing instruments are also not prone to collecting dust and dirt. This instrument is located on the E13 SIRS tower and the down pointing PSP does not show a discontinuity at either time, which further discounts the dirty instrument theory. Site operations were asked to check the instrument mount to see if it was loose possibly causing the instrument to change its position, and they reported that the mount seemed secure and stable. So as of now, the cause of this issue is a mystery. Compare with other down pointing instruments to help ascertain if data on one side of the discontinuity or the other are "better." Perform an error analysis to determine if this would introduce a significant error in the role the data stream plays in a user's research.

Subject:	SGP/MFRSR/C1 - Incorrect alltime units
DataStreams:	sgpmfrsrC1.b1
Description:	Units of alltime_hemisp_broadband and alltime_hemisp_narrowband_filter(N) are incorrect. They should be counts. A low priority reprocessing task has been submitted to correct this metadata error.
