The spheRlab is an R package with numerous functions related to spherical geometry. The package is intended in particular for analysis and plotting of geophysical unstructured-grid data, for example data produced by the Finite Element (or volumE) Sea-ice Ocean Model (FESOM).
The original development of spheRlab has been driven by personal technical needs to be addressed while working with unstructured-grid data in the context of climate model development and research. The package content is in particular shaped by data produced by the Finite Element (or volumE) Sea-ice Ocean Model (FESOM) of the Alfred Wegener Institute (AWI), and a combined usage with the Climate Data Operators (CDO).
