TrenchR (version 1.1.1)

monthly_solar_radiation: Average Monthly Solar Radiation

Description

The function estimates average monthly solar radiation (W m^-2 d^-1) using basic topographic and climatic information as input. Cloudiness is stochastically modeled, so output will vary between functional calls. Based on Nikolov1992;textualTrenchR.

Usage

monthly_solar_radiation(lat, lon, doy, elev, T_a, hp, P)

Value

numeric average monthly solar radiation (W m^-2).

Arguments

lat

numeric latitude (degrees).

lon

numeric longitude (degrees).

doy

numeric day of year (1-366).

elev

numeric elevation (meters).

T_a

numeric mean monthly air temperature (C).

hp

numeric mean month relative humidity (percentage).

P

numeric total monthly precipitation (mm).
