Altitude: Solar Altitude Angle

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

Description

This function solar altitude angle (in degrees) for a given day of year and location.

Usage

Altitude(DOY, Lat, Lon, SLon, DS)

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

Examples

#Calculating solar altitude angle for two consecutive days

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

alpha <- Altitude(DOY, Lat = 45, Lon=0, SLon=0, DS=60)
#Note: only the difference between Lon and SLon matters not each value

plot(DOY, alpha)
