rayExt: calculation of extraterrestrial radiation

In frimane/SolMultinomClass: Solar Radiation Classification Using Nonparametric Multinomial Mixture Modeling

Description

function that calculates the extraterstrial radiation knowing the latitude, longitude and the time-step wanted

Usage

rayExt(phi = 0, lg = 0, tStep = 300)

Arguments

phi	latitude of the considered site
lg	longitude of the considered site
tStep	time-step wanted, gived by second (example: for 5min; tStep = 300)

Value

An object of class matrix, each line represents one day and each column represents one time-step

Examples

# calculate the extraterrestrial radiation for a given site (latitude = 15, longitude = 15)
# with a time-step of 1 minute
matr <- rayExt(phi = 15, lg = 15, tStep = 60) 

# plot a random day example
plot(1:(60*24), matr[sample(1:366, 1), ], type = "l")
