The HERMESv3_GR emission processing system

Dear CMAS Community,

We are happy to announce the release of the High-Elective Resolution Modelling Emission System version 3 - Global Regional Module (HERMESv3_GR), an open source, parallel and stand-alone multi-scale emission processing system that calculates emissions from different sources, regions and pollutants on a user-specified global or regional grid. The user can flexibly define combinations of existing up-to-date global and regional gridded emission inventories and apply country-specific scaling factors and masks. Each emission inventory is individually processed using user-defined vertical, temporal and
speciation profiles that allow obtaining emission outputs compatible with multiple chemical mechanisms (e.g. CB05, RADM2). The selection and combination of emission inventories and databases is done through detailed configuration files providing the user with a widely applicable framework for designing, choosing and adjusting the emission modelling experiment without modifying the HERMESv3_GR source code. The generated emission fields have been successfully tested in different atmospheric chemistry models, including CMAQ at multiple spatial and temporal resolutions. Moreover, the emission core module of HERMESv3_GR is parallelized using a domain decomposition strategy, which allows
decreasing the execution time and memory consumption of the system.

HERMESv3_GR is an in-house tool fully developed by the Barcelona Supercomputing Center and is distributed free of charge under the licence GNU GPL v3.0.

A paper with a description of the system is available at GMD:

The code and a user guide is available in the following git repository:

Due to our limited time and resources, the developing team can not guarantee a regular support. Nevertheless, we will be happy to provide advice for new users.

Best wishes


Dear @marc.guevara,

Thanks for sharing this. Is there any user’s guide for this tool, please?

Thanks and kind regards.


Dear @Catalyst2682,

You can find a user guide of the tool in the wiki of the HERMESv3_GR gitlab repository:
There is also a benchmark case to ensure that the installation process was successful:

Dear @marc.guevara,

Thanks for the prompt response. I have sent you an email to join the mail listing as requested on your site. Kindly treat the request.

Thanks and regards.
