SWDN_2_PAR R Documentation
downward shortwave radiation to PAR
Description
calculate photosynthetically available radiation (PAR) from incident
downward shortwave radiation (SWDN)
Usage
SWDN_2_PAR(SWDN)
Arguments
SWDN
numeric vector; downward shortwave radiation (W m-2)
Details
uses the mean result from Britton and Dodd (1976) table I. Averages the
tables two values for Apr-May together, then averages all bimonthly
averages.
Value
numeric vector containing PAR values (umol m-2 s-1)
