SGP/NIMFR/C1 - Intermittent noise, 500nm
DataStreams:sgpnimfrC1.a0, sgpnimfrC1.b1, sgpnimfrlangleyC1.c1, sgpnimfrlangplotC1.c1
Description:
Values of direct_normal_narrowband_filter2 (500 nm) were erratic at times, likely the 
result of a poor connection in the signal.  The erratic behavior is last seen on 20081101, 
before the connectors were cleaned.
Measurements:sgpnimfrC1.b1:
  • Direct Normal Narrowband Irradiance, Filter 2(direct_normal_narrowband_filter2)
  • Narrowband Direct Horizontal Irradiance, Filter 2(direct_horizontal_narrowband_filter2)
sgpnimfrlangleyC1.c1:
  • optical depth for the Direct Narrowband Filter2(barnard_optical_depth_filter2)
  • Langley regression Io, adjusted to 1AU, Barnard, Direct Narrowband Filter2(barnard_solar_constant_sdist_filter2)
  • optical depth for the Direct Narrowband Filter2(michalsky_optical_depth_filter2)
  • percentage of initial points used in final linear fit for the Direct Narrowband

  • solar constant corrected for solar distance for the Direct Narrowband Filter2(michalsky_solar_constant_sdist_filter2)
  • standard deviation around regression line for the Direct Narrowband Filter2(michalsky_standard_deviation_filter2)
  • Langley regression Io, Michalsky, Direct Narrowband Filter2(michalsky_solar_constant_filter2)

  • number of points used in final linear fit for the Direct Narrowband Filter2(barnard_number_points_filter2)
  • rejection flag for Direct Narrowband Filter2(michalsky_badflag_filter2)
  • rejection flag for Direct Narrowband Filter2(barnard_badflag_filter2)
  • error in optical depth (slope) of final linear fit for the Direct Narrowband
