Subject:
SGP/SIRS/E12 - Failed ventilator fan
DataStreams:sgpsirsE12.b1, sgpsirs20sE12.a0
Description:
Ventilator fan for the downwelling shortwave hemisheric failed during this time period.  
The thermal effects of daytime heating will skew the radiometric measurements of the 
thermopile instrument.
Suggestions: 
No known correction can be applied.  Disregard this data or use with caution.
Measurements:sgpsirs20sE12.a0:
  • Instantaneous Downwelling Hemispheric Shortwave, Pyranometer Thermopile Voltage(inst_global)

sgpsirsE12.b1:
  • Downwelling Shortwave Hemispheric Irradiance, Ventilated Pyrgeometer, Standard
    Deviation(down_short_hemisp_std)
  • Downwelling shortwave hemispheric irradiance, pyranometer, maxima(down_short_hemisp_max)
  • Downwelling Shortwave Hemispheric Irradiance, Pyranometer, Minima(down_short_hemisp_min)
  • Down-welling unshaded pyranometer voltage(down_short_hemisp)
