Functions

Fdif_Neustift(doy, zeni, Rg)	Estimate the fraction of diffuse radiation.
LUTshad(solpars, timecorr, lat, elvgrid, ...)	Get the look-up-table for topographic shading for one year.
LUTsvf(elvgrid, maskgrid, slopegrid, ...)	Get the look-up-table for the sky-view-factor for one year.
calcRad(solPars, timecorr, doy, hour, lat, ...)	Gets the combined all-sky shortwave radiation (direct + diffuse).
correctRadiation(lat, lon, timezone_lon, ...)
haversine(lat1, lon1, lat2, lon2)	Get the distance between two points using the haversine formula.
