Installing the OpenIFS-AC sources
We recommend to create a new installation for OpenIFS/AC. This will preserve your original OpenIFS installation and will allow you to use the standard (meteorological) model and the atmospheric composition model interchangeably.
Installing the model sources and building the model (including acceptance tests) requires 3-4 GB of disk space. The additionally required climatological data packages are not yet included; their installation is described below and will require further disk space.
Method 1: We recommend to create a new installation for OpenIFS/AC. This will preserve your original OpenIFS installation and will allow you to use the standard (meteorological) model and the atmospheric composition model interchangeably.
To proceed you should:
- create a new home for the OpenIFS/AC installation, e.g. a directory called
openifs-ac. - change into your new directory and unpack therein the original OpenIFS model sources: tar xvzf oifs43r3v2.tgz
- in a second step, in the same folder unpack the OpenIFS/AC sources: tar xvzf openifs-ac.43r3.v1.tgz

Note that some files of the original model will be replaced. It is therefore essential to install the original OpenIFS 43r3v2 sources first before installing the OpenIFS/AC sources. |
Method 2: Alternatively, in order to convert the standard OpenIFS model to OpenIFS/AC the additional software package for composition needs to be installed into an existing OpenIFS installation. We recommend to create first a backup of your original installation before proceeding.
For the conversion you should:
- change into your $OIFS_HOME directory where OpenIFS is installed: cd $OIFS_HOME
- in this directory extract the downloaded source package: tar xvzf openifs-ac.43r3.v1.tgz
