Santis

The vCluster santis is dedicated to Climate and Weather applications. It includes the following:

  • EXCLAIM : Project for ICON-based km-scale climate simulations
  • Projects by C2SM community members
  • User lab projects in climate and weather domains

User Environments (uenvs)

uenv Description
icon/25.2:v3 Build and run ICON
netcdf-tools/2025:v1 Pre- and post-processing tools

You can find the most important commands when working with uenvs on the CSCS Docs pages .

netcdf-tools

The netcdf-tools uenv provides a set of CLI tools and GUI tools frequently used in climate and weather workflows, including cdo, ncview, ncdump and others.

It is recommended that the netcdf-tools uenv is loaded with the --view=netcdf argument to instantly access all of the tools that are shipped with this uenv:

uenv start --view=netcdf netcdf-tools/2025:v1

The software is now available, e.g.:

which cdo
# /user-environment/env/netcdf/bin/cdo

More information about the netcdf-tools uenv can be found at the CSCS Docs page .

Pre-release uenvs

User environments that are not (yet) part of the official CSCS uenv registry can be found in the following folder:

/capstor/store/cscs/userlab/cwd01/leclairm/uenvs/images
uenv Description
/capstor/store/cscs/userlab/cwd01/leclairm/uenvs/images/climtools_25.2.sqfs Like netcdf-tools but with additional software such as git-lfs and eccodes
/capstor/store/cscs/userlab/cwd01/leclairm/uenvs/images/climtools_25.2_v2.sqfs Like netcdf-tools but with additional software such as git-lfs, eccodes and icontools
/capstor/store/cscs/userlab/cwd01/leclairm/uenvs/images/sirocco_25.9.sqfs Sirocco

Note that the climtools uenvs should also be loaded with the --view=modules argument.
