OpenRadiation: Open Sky Solar Radiation

In solrad: Calculating Solar Radiation and Related Variables Based on Location, Time and Topographical Conditions

Description

This function returns open sky solar radiation (in W/m2) for a given day of year and location.

Usage

OpenRadiation(DOY, Lat, Lon, SLon, DS, Elevation)

Arguments

DOY	Day of year
Lat	Latitude (in degrees)
Lon	Longitude in degrees
SLon	Standard longitude (based on time zone) in degrees
DS	Daylight saving in minutes
Elevation	Elevation of the site in meters

Examples

#Calculating open sky solar radiation for two consecutive days on 45 degree latitude and
# 10 degree longitude and at 100 m altitude.

DOY <- seq(0, 2, .05)

Sopen <- OpenRadiation(DOY, Lat = 45, Lon=10, SLon=10, DS=0, Elevation = 100)
#Note: only the difference between Lon and SLon matters not each value

plot(DOY, Sopen)
