BALTRAD

Welcome to this “cookbook”, where “recipes” are collected. This is intended to constitute a documentation reference collection of data processing algorithms. Each algorithm recipe is documented in a standardized way, enabling them to be coded as part of the BALTRAD code base or an external system. The important thing is that the community can focus this effort in a harmonized way.
