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)
Field tech reports the datalogger program was corrected on 4/27/04. Archive data review
shows this was not the case and the corrected datalogger program was uploaded sometime
late day 5/4/04. The end date for this DQR was chosen to be 5/5/04 0000 the first full day
of the correct datalogger program.
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)*123.27
US(corrected) = (US/113.19)*127.75
NIP(corrected)= (NIP/120.17)*126.69
DS(corrected) = (DS/118.46)*126.56 |
