Subject:
SGP/SIRS/E4 - Dirt on Dome
DataStreams:sgpsirsE4.b1, sgpsirsE4.00, sgpsirs20sE4.a0
Description:
The downwelling shortwave hemispheric radiation data are suspect.  The PSP dome appears to 
have been very dirty, especially during times when the sun angles were low.
Suggestions: 
use of specified data not recommended
Measurements:sgpsirs20sE4.a0:
  • Instantaneous Downwelling Hemispheric Shortwave, Pyranometer Thermopile Voltage(inst_global)

sgpsirsE4.00:
  • (Raw data stream - documentation not supported)
more
sgpsirsE4.b1:
  • Downwelling Shortwave Hemispheric Irradiance, Pyranometer, Minima(down_short_hemisp_min)
  • Downwelling Shortwave Hemispheric Irradiance, Ventilated Pyrgeometer, Standard
    Deviation(down_short_hemisp_std)
  • Downwelling shortwave hemispheric irradiance, pyranometer, maxima(down_short_hemisp_max)
  • Down-welling unshaded pyranometer voltage(down_short_hemisp)
