SGP/SIRS/E24 - Reprocessing Notice (RID 216)
DataStreams:sgpsirs20sE24.a0, sgpsirsE24.b1, sgpsirsE24.00
Description:
See below for details of reprocessing that was completed on 20160127.  Original 
DQR category: 4 (Red, Incorrect).

-----------------------------------------------------------

Calibration coefficient for the downwelling diffuse measurement (8-48 B&W Eppley 
instrument) was incorrect after the instrument replacement 8/18/2005.

Affected downwelling diffuse irradiance data can be corrected:
Irr(corr) = Irr(uncorr) / 122.85 * 112.85 (or a overall multiplier of .9186)
Suggestions: 
Measurements:sgpsirsE24.b1:
  • Downwelling shortwave diffuse hemispheric irradiance, pyranometer, maxima(down_short_diffuse_hemisp_max)
  • Downwelling Shortwave Diffuse Hemispheric Irradiance, Pyranometer, Standard
    Deviation(down_short_diffuse_hemisp_std)
  • Downwelling Shortwave Diffuse Hemispheric Irradiance, Pyrgeometer, Minima(down_short_diffuse_hemisp_min)
  • Downwelling Shortwave Diffuse Hemispheric Irradiance, Ventilated Pyranometer(down_short_diffuse_hemisp)

sgpsirsE24.00:
  • (Raw data stream - documentation not supported)
more
sgpsirs20sE24.a0:
  • Instantaneous uncorrected downwelling shortwave diffuse, shaded pyranometer
    thermopile voltage(inst_diffuse)
