Description

CPAR is corrected photosynthetically active radiation or corrected irradiance. CPAR is often calculated as part of SeaBird's CTD processing software, which calculates CPAR (as a percent) using the following equation:

Corrected Irradiance [CPAR] = 100 * ratio multiplier * underwater PAR / surface PAR

(Ratio multiplier = scaling factor used for comparing light fields of disparate intensity, input in .con or .xmlcon file entry for surface PAR sensor; Underwater PAR = underwater PAR data; Surface PAR = surface PAR data)

[Above equation obtained from the Seasoft V2: SBE Data Processing User's Manual Software Release 7.26.8 and later]
