Subject:
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)
