CNRM Open Source Site

The Wiki contains information on the installation and usage of the MDSSFTD tool. Furthermore, the inputs and outputs are detailed here.

The CNRM is happy to release the open source version of the MDSSFTD code that allows to calculate the solar radiation incident on the surface based on SEVIRI/MSG observations.

Dear Crocus users,

The cen branch (stable branch for Crocus users) has just been updated with numerous modifications including:

- merge with all technical modifications of SURFEX v8.1 master branch : http://www.umr-cnrm.fr/surfex//spip.php?rubrique151

- merge of various new developments which can optionnally be activated :

Multiphysical system ESCROC (Ensemble System Crocus). Documentation: https://opensource.umr-cnrm.fr/projects/snowtools_git/wiki/Multiphysics
Explicit representation of impurities : https://opensource.umr-cnrm.fr/projects/snowtools_git/wiki/Explicit_representation_of_impurities
Snow management in ski resorts: https://opensource.umr-cnrm.fr/projects/snowtools_git/wiki/Crocus-RESORT
Modification of radiation corrections on explicit slopes: https://opensource.umr-cnrm.fr/projects/snowtools_git/wiki/Radiation_on_slopes
Add topographic metadata in diagnostic files: https://opensource.umr-cnrm.fr/projects/snowtools_git/wiki/Output_diagnostics
Coupling of Crocus snowpack model with Multiple Energy Balance scheme for snow-vegetation interactions (documentation not yet available)
MEPRA expert system for avalanche hazard diagnostic (documentation not yet available)
SYTRON scheme for erosion/accumulation of drifted snow in the massif geometry (documentation not yet available)

The main technical consequence for standard users is that the namelists from version 8 are no longer supported. Users must adapt their namelists from this version 8.1 example: https://opensource.umr-cnrm.fr/projects/snowtools_git/repository/revisions/master/entry/DATA/OPTIONS_V8.1_NEW_OUTPUTS_NC.nam

Note also that the results of standard applications on slopes are likely to be affected by the changes in the radiations parameterization. There was not any modification in the main snowpack scheme itself.

Note that we will ask all users to update their code in case of bugs in older versions.
(git pull and new compilation)

If despite all our tests, you meet troubles with this new version, please report them through the support interface: https://opensource.umr-cnrm.fr/projects/snowtools_git/issues/new

This new release is the result of a long work from many contributors, including a major investment of Rafife Nheili for merging.

Thank you
Matthieu

Dear Crocus users,

The main branch for Crocus users was renamed "cen" instead of the complex name "lafaysse_fromV8trunk_withmeb".

To be able to receive the next updates, all of you who installed this branch must do the following command to refer to the new remote name :

git branch lafaysse_fromV8trunk_withmeb --set-upstream origin/cen

Then, optionnally, you can also rename your local branch name for consistency with:

git branch -m lafaysse_fromV8trunk_withmeb cen
