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!
