Subject:
SGP/SIRS/E10 - Reprocessing Notice (RID 290)
DataStreams:sgpsirsE10.b1, sgpsirsE10.00
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 SGP/SIRS/E10 and each one minute irradiance value perform the 
following calculations by instrument:
DD(corrected) = (DD/107.24)*114.63
US(corrected) = (US/113.19)*117.46
NIP(corrected)= (NIP/120.17)*119.26
DS(corrected) = (DS/118.46)*122.78
