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 |
