SGP/NIMFR/E13 - NIMFR Centrovision filter leakage
DataStreams:sgpnimfrE13.a0, sgpnimfrE13.b1
Description:
Testing of the batch of centrovision filters being used in the NIMFR EF13
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.

  • Direct Normal Narrowband Irradiance, Filter 1(direct_norm_narrowband_filter1)
  • Direct Normal Narrowband Irradiance, Filter 3(direct_norm_narrowband_filter3)

SGP/NIMFR/E13 - Instrument failure
DataStreams:sgpnimfrE13.00, sgpnimfrE13.a0, sgpnimfrE13.b1
Description:
Head temp values frequently dropped to 0, -50, or -100 degrees Celsius.  Often this causes 
the filters to drop to values of zero (or act erratic) as well.

On 9/23 the instrument was pulled from service and the mentor found significant damage to 
the instrument due to overheating.  Instrument will be rebuilt.
