The data directory contains the following gzipped tarfiles, all of which should be downloaded.
| Contents of directory data: | Description |
|---|---|
| 40r1/ | Contains OpenIFS versions based on Cycle 40 Release 1 of IFS. |
| Info |
|---|
These files are the same for all OpenIFS experiments. To save space for multiple users, it's recommended they are placed somewhere central and not copied to each user run directory. The sample job scripts provided assume that links are created from these files to the user run directory. We suggest creating a directory ifsdata somewhere and unpacking the files there. |

| Filename | Size | Description |
|---|---|---|
| <version>/ifsdata_climatology_<version>.tgz | 15Mb | Contains the various long-lived gases and aerosol climatologies used by the model. Unpacks into a directory called climate. |
| <version>/ifsdata_<version>_climate.tar.gz | 2.5Gb | Contains ozone climatology for all supported horizontal and vertical resolutions, including full and reduced Gaussian grid versions. For example, unpacks into two directories, 40 and 40r1. The files in 40r1 link to the files in 40 but allow for model version specific changes. n.b. On some systems, this file is too big for gzip to uncompress. In which case download the specific resolutions you need. |
| <version>/ifsdata_<version>_climate_t*.tar.gz | varies | These files do not need to be downloaded if you download the above ifsdata_<version>_climate.tar.gz. These contain the same data but split one file per horizontal resolution. If you want to save space, you can download just the resolutions you intend working with. |
| <version>/ifsdata_rtables_<version>.tar.gz | <1Mb | Contains namelists defining the supported grid resolutions for the radiation scheme. File name suffix refers to the type of grid and last 3 digits refers to the horizontal resolution. Unpacks to a directory: rtables. |
| <version>/ifsdata_vtables_<version>.tar.gz | <1Mb | Contains namelists defining the coefficients for the supported vertical resolutions. File name suffix refers to the number of levels. Unpacks to a directory: vtables. |
