Description: | 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 |
