Solar Radiation

Calculates the hourly solar radiation (direct+diffuse+reflected) for a DEM integrated over on year

File Information

Solarradiation.m is used to calculate the solar radiation for a digital elevation model integrated over one year. Radiation is calculated depending on latitude, elevation, horizon shading, slope, aspect, time of year and hour of the day (day length/season) and ground reflectance.
Temporal resolution of radiation calculation over sunshine hours can be set freely (1 hour default).
The script follows the approach by Kumar et al (1997). Simple unweighed 4 nearest neighbour gradient calculation is used and relief shading is not accounted for.

a GIS environment. Int.J.Geogr.Info.Sys. 11(5), 475-497
