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: > **[HERMESv3, a stand-alone multi-scale atmospheric emission modelling framework...](https://www.geosci-model-dev.net/12/1885/2019/gmd-12-1885-2019.html)** > > Abstract. We present the High-Elective Resolution Modelling Emission System version 3 > (HERMESv3), an open source, parallel and stand-alone multi-scale atmospheric > emission modelling framework that computes gaseous and aerosol emissions for > use... The code and a user guide is available in the following git repository: > **[Earth Sciences / hermesv3\_gr](https://earth.bsc.es/gitlab/es/hermesv3_gr)** > > Earth Sciences Gitlab 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 Marc ---

Dear @Catalyst2682, You can find a user guide of the tool in the wiki of the HERMESv3\_GR gitlab repository: [https://earth.bsc.es/gitlab/es/hermesv3\_gr/wikis/user\_guide](https://earth.bsc.es/gitlab/es/hermesv3_gr/wikis/user_guide) There is also a benchmark case to ensure that the installation process was successful: [https://earth.bsc.es/gitlab/es/hermesv3\_gr/wikis/examples/benchmark](https://earth.bsc.es/gitlab/es/hermesv3_gr/wikis/examples/benchmark) ---
