HourAngle: Solar Hour Angle

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

Description

This function returns solar hour angle for a given day of year, and location.

Usage

HourAngle(DOY, Lon, SLon, DS)

Arguments

DOY	Day of year
Lon	Longitude in degrees
SLon	Standard longitude (based on time zone) in degrees
DS	Daylight saving in minutes

Examples

#Calculating solar hour angle for two consecutive days

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

h <- HourAngle(DOY, Lon=0, SLon=0, DS=60)
#Note: only the difference between Lon and SLon matters not each value

plot(DOY, h)
