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

# NOT RUN {
#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)
# }
