SGP/SIRS/C1 - SW direct normal data drop out
DataStreams:sgpsirsC1.b1, sgpsirs20sC1.a0
Description:
NIP cable had failed during this time period.

Short_direct_normal data are not recoverable during this time period. However, it can be 
reconstructed using the following formula for each one minute data:
   short_direct_normal = (down_short_hemisp-down_short_diffuse_hemisp)/cos(zenith angle)
Measurements:sgpsirs20sC1.a0:
  • inst_direct_normal
sgpsirsC1.b1:
  • Radiation, shortwave, direct normal irradiance, 1-min avg(short_direct_normal)
  • short_direct_normal_std
  • Shortwave Direct Normal Irradiance, Pyrheliometer, Maxima(short_direct_normal_max)
  • Shortwave Direct Normal Irradiance, Pyrheliometer, Minima(short_direct_normal_min)

SGP/SIRS/C1 - Reprocessed: Upwelling shortwave
DataStreams:sgpsirsC1.b1, sgpsirs20sC1.a0
Description:
The upwelling shortwave hemispheric data were bad 20090914-20091009 due to a broken 
instrument cable.  The cable was replaced on 10/09 at 1711 GMT but the leads were reversed. The 
leads were corrected 10/19 at 2001 GMT.

The data for 20090914-20091019 have been reprocessed. The bad data from 20090914-20091009 
were set to missing in the newly available reprocessed data set. The 20091009-20091019 
data were corrected by applying a (-1) multiplier.
Measurements:sgpsirs20sC1.a0:
  • inst_up_short_hemisp
sgpsirsC1.b1:
  • Radiation, shortwave, at 10-m height, upwelling hemispheric irrad., 1-min avg(up_short_hemisp)
  • up_short_hemisp_std
  • Upwelling Shortwave Hemispheric Irradiance, Unventilated Pyranometer, Minima(up_short_hemisp_min)

SGP/SIRS/C1 - Failed Upwelling SW cable
DataStreams:sgpsirsC1.b1, sgpsirs20sC1.a0
Description:
The upwelling shortwave hemispheric (up_short_hemisp) data were missing or incorrect due 
to a bad cable.  Cable was replaced on 6/30 and the problem was resolved.
Measurements:sgpsirs20sC1.a0:
