Downwelling Irradiance of PAR (Ed_PAR)

Input

  1. Downwelling irradiance (Ed) for each wavelength. If coming from an OCR504 (four wavelengths), the remaining wavelengths must be estimated from a clear sky model.

Ancillary Requirements

  1. Clear sky modeled downwelling irradiance.

MATLAB m-file

ComputePAR.m

Output

Downwelling irradiance of PAR in units of micro einsteins per meter square per second, Ed_PAR.
