A new version of the CY40T1 export codes was released on April 24, 2017.

This version includes a number of fixes + Alaro-v1b changes. The companion PDF file describes the set of technical code changes that have entered the MF GIT repository while building this new source code version. The former, first export branch was based on CY40T1_bf.05 (see the article). The new version of based on CY40T1_bf.07.

On the side of the Alaro CMC, a specific documentation about v1b has been written. See also the set of two namelists for Alaro v1a and v1b.

On the side of the Arome CMC, apart from code fixes, this export version has been validated for Arome-France 3D-VAR and was found bit-reproducible with respect to the previous version (including all operational types of observations, and tested for one network).
The Aladin forecast model configuration also basically is not changed.

For the local installation, it is very highly recommended a FULL installation of the code, not an incremental one (w/r to the first export). Indeed, several changes affect modules and codes that possibly create compile dependencies. Therefore, it seems much safer to install the full new version in one go.

For this purpose, the full source code is available in the tar-package available on "hendrix": martinezs/pub/src/arp/cy40/cy40t1_bf.07.tar.gz

Namelists and const files for Arome-France are kept unchanged w/r to the previous version. For reminder, they can be found at: /home/martinezs/pub/export/cy40t1_bf.05 (see details).
