SGP/SIRS/E24 - Reprocessing Notice (RID 257)
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).

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

During the PIR coefficient change from 4/coeffs to 1/coeff, the downwelling diffuse 
hemispheric instrument (Eppley 8-48) coefficient was inadvertently changed to 122.85 and should 
have been 112.85 W/m2/mV. 

Perform the following calculation to correct the data, DD=downwelling diffuse instrument:  

  DD(new)[W/m2]=( DD(old)[W/m2]/122.85[W/m2\mV] )* 112.85[W/m2/mV]
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)
