Subject:
SGP/SIRS/E8  - Reprocessing Notice (RID 291)
DataStreams:sgpsirsE8.b1, sgpsirsE8.00
Description:
See below for details of reprocessing that was completed on 20150929.  Original 
DQR category: 4 (Red, Incorrect).

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

During the pyrgeometer instrument (PIR) changeout a datalogger program was loaded with 
incorrect calibration coefficients for the shortwave instruments.  The affected measurements 
(instruments) were: downwelling diffuse (8-48), upwelling shortwave (PSP), direct normal 
(NIP) and downwelling shortwave (PSP)

Recalculate irradiances by determining original mV signal and reapplying the correct 
calibration coefficients.  For each one minute irradiance value perform the following 
calculations by instrument:
DD(corrected) = (DD/107.24)*116.37
US(corrected) = (US/113.19)*121.78
NIP(corrected)= (NIP/120.17)*122.47
DS(corrected) = (DS/118.46)*122.34
