Reminder! The CHIMERE chemistry-transport model is a free-to-download model under the GNU General Public License (since 2000). This means that the development team provides the model, the corresponding documentation, subsequent bugfixes and version updates and all necessary inputs for a test run. We would like to kindly remind the users that while the development team tries their best to respond to issues arising in the model in its original form we will not respond to issues occurring after user-made modifications in the source code. If you encounter issues after modifying the source code, it is recommended to run the model in its original form before contacting the development team.

If you would like to contact the developers please follow the instructions here.
