icclim documentation#

Welcome to icclim documentation. icclim (Index Calculation for CLIMate) is a Python library to compute climate indices. It is built on a open source stack made of xclim, xarray, dask and of course NumPy.


icclim documentation is currently under construction. We try to follow the diataxis principles to build a comprehensive user focused documentation.

A few notes about icclim#

  1. Input datasets must be compliant to the CF convention.

  2. Currently, icclim doesn’t support spatial subsetting, i.e. it processes whole spatial area.

  3. icclim works with unsecured OPeNDAP datasets as well.

  4. icclim developer repository can be found here: cerfacs-globc/icclim


Add If you encounter a bug or an issue while using icclim, don’t hesitate to open a ticket on our github.
