The Offline Surface Model (HTESSEL) is provided free-of-charge and licenses are provided per institution.

The OSM can be downloaded from the ECMWF ftp site. Only licensed users are provided with the username and password to access the ftp site.

For more information, or to request a license, please email: openifs-support@ecmwf.int.

Download source code

To obtain the source code from the ftp site, change directory to the osm-htessel directory and retrieve the latest source code (filename may be different than shown):

% ftp ftp.ecmwf.int
user: openifs
cd src/osm-htessel
ls
get surf_CY40R1_control.tar.gz
bye

% tar zxf surf_CY40R1_control.tar.gz

The tarfile unpacks into a directory containing the following files (some differences may exist between versions):

% ls
compile_fcm.ksh surf

compile_fcm.ksh -- this is a script used at ECMWF to compile the OSM. It is provided for guidance only and cannot be used external to ECMWF without modification.

surf -- this directory contains all the source code and compilation scripts.
