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.
