Convert photosynthetically active radiation (PAR) to shortwave radiation (SW). Uses a fixed ratio between PAR and SW, ignoring the minor seasonal changes in this ratio (see Britton and Dodd (1976)).

Usage

convert_PAR_to_SW(par, coef = 0.473)

Arguments

par

Vector of photosynthetically active radiation (400-700 nm; umol/m^2/sec).

coef

Numerical coefficient to convert PAR (umol/m^2/sec) to SW (W/m^2). Defaults to value from Britton and Dodd (1976).

Value

Numeric vector of shortwave values with units W/m^2.

Examples

convert_PAR_to_SW(par=400, coef=0.47)
#> [1] 188
convert_PAR_to_SW(1000)
#> [1] 473
