SGP/SIRS/C1 - NIP failure
DataStreams:sgpsirs20sC1.a0, sgpsirsC1.b1
Description:
The short_direct_normal (NIP instrument) cable failed during this time period.	Data are 
not recoverable.

Users can derive an estimate of direct normal values using the following formula:
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 - NIP Failure
