The files here are infilling databases. They are used for the 'infilling' step of simple climate model assessment. This involves inferring emissions of one species (e.g. HFC32) based on emissions of another species (e.g. CO2) and relationships between these two species seen in other scenarios. For more details about infilling, see Lamboll et al., 2020.

The database is provided in three different formats. The versions of the scenarios used to compile this database is provided in the versions.json file.

The database was derived using the code in this repository: https://github.com/iiasa/emissions_harmonization_historical. The filenames are composed of identifiers related to the processing of each of the different input data sources. To identify the exact meaning of these identifiers, please see the processing code in https://github.com/iiasa/emissions_harmonization_historical.
