SAGA-GIS Module Library Documentation (v2.1.3)

Module Monthly Global by Latitude

Orbital parameters used here are based on the work of Andre L. Berger and its implementation from the NASA Goddard Institute for Space Studies (GISS). Berger's orbital parameters are considered to be valid for approximately 1 million years.
