Convert from photosynthetically active to shortwave radiation
Source:R/convert_PAR_to_SW.R
convert_PAR_to_SW.Rd
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)).
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).
Examples
convert_PAR_to_SW(par=400, coef=0.47)
#> [1] 188
convert_PAR_to_SW(unitted::u(1000, "umol m^-2 s^-1"))
#> unitted numeric (W m^-2)
