Description Usage Arguments Value

View source: R/calculate_globrad.R

Description

Uses day of year (doy) and latitude to determine extraterrestrial solar radiation and daylength, which is then used to calculate global radiation using angström formula

Usage

1
CalcGlobRad(doy, SunHour, lat, a0 = 0.25, b0 = 0.5)

Arguments

doy

day of year

SunHour

sunshine duration hours, same length as doy

lat

latitude in decimal degrees

a0

angström parameter a, defaults to 0.25

b0

angström parameter b, defaults to 0.5

Value

a sequence of global radiation in MJ m^-2 d^-1 with the length of doy
