Description Usage Arguments Value Note References See Also Examples

View source: R/ssd2rad.R

Description

The function converts values of sunshine duration (in hours) to global radiation (in J/m2/s).

Usage

1
ssd2rad(S, doy, a = 0.25, b = 0.5, rho = 50.29)

Arguments

S

Sunshine duration (hours)

doy

Julian day (for northern hemisphere only)

a, b, rho

site specific conversion parameters, must be fitted to measured data.

Value

Estimated value of global radiaton in J/m2/s.

Note

Don't forget to fit the function parameters to site specific values!
