# User inputs You can download the different files by clicking the download button below, or suggest edits by filling in a form. For any question or remark about this data, please contact the maintainers of _mescal_ (for example, matthieu.souttre@polymtl.ca). ## Mapping between ESM technologies and LCI datasets The mapping file links the ESM technologies, resources and vectors with LCI datasets. Here, we present a generic mapping between typical ESM technologies, resources and vectors, with LCI datasets from [ecoinvent 3.10.1](https://support.ecoinvent.org/ecoinvent-version-3.10.1) (cut-off), complemented with additional datasets from [premise](https://github.com/polca/premise) (see [this notebook](https://github.com/matthieu-str/mescal/blob/master/dev/import_premise_db.ipynb)) and [carculator_truck](https://github.com/Laboratory-for-Energy-Systems-Analysis/carculator_truck) (see [this notebook](https://github.com/matthieu-str/mescal/blob/master/dev/carculator.ipynb)). The table below has the following columns: - **Name**: Name of the ESM technology, resource or vector. - **Type**: Type of the LCI dataset (operation, construction, resource or flow). - **Product**: Name of the corresponding LCI dataset product. - **Activity**: Name of the corresponding LCI dataset activity.
## Unit conversion factors The previous mapping file goes with a set of unit conversion factors to convert ESM technology, resource and vector physical units to LCI dataset units. The table below has the following columns: - **Name**: Name of the ESM technology, resource or vector. - **Type**: Type of the LCI dataset (operation, construction, resource or flow). - **Value**: Conversion factor value. - **LCA unit**: Unit used in LCI datasets. - **ESM unit**: Unit used in ESM. - **Assumptions & Sources**: Any assumptions made or sources used to determine the conversion factor.
## Energy System Model The technologies and resources presented in the mapping files above correspond to those used in the Energy System Model (ESM). The table below has the following columns: - **Name**: Name of the ESM technology. - **Flow**: Name of the ESM resource or vector. - **Amount**: Amount of resource or vector used/produced by the technology (positive for production, negative for consumption).
## Mapping between ESM vectors and CPC categories When removing double-counted flows in LCI datasets, we identify flows based on their correspondence to CPC categories. Therefore, each ESM vector is mapped to one or more CPC categories. The table below has the following columns: - **Vector**: Description of the ESM vector. - **CPC**: List of corresponding CPC categories.
