TrenchR (version 1.1.1)

diurnal_radiation_variation: Hourly Solar Radiation

Description

The function estimates hourly solar radiation (W m^-2 hr^-1) as a function of daily global solar radiation (W m^-2 d^-1). Based on Tham2010;textualTrenchR and AlRawahi2011;textualTrenchR.

Value

numeric hourly solar radiation (W m^-2).

Arguments

doy

numeric the day of year.

S

numeric solar radiation (W m^-2 d^-1).

hour

numeric hour (0-24).

lon

numeric longitude (degrees).

lat

numeric latitude (degrees).
