Methane emissions for functional urban areas

Methane emissions estimates for Functional Urban Areas (FUAs) from Schiavina et al. (2019) providing information that links grid cells in the World Bank’s global XCH4 database to IDs for FUAs and national administrative units.The database uses information from the European Space Agency’s Sentinel-5P (S-5P) (TROPOMI) satellite platform. It downloads monthly updates for georeferenced measures of XCH4—the column-averaged, dry-air mole fraction of the gas— and filters the data for atmospheric concentration anomalies that identify local emissions. The filter uses the methodology of Hakkarainen et al. (2019). See Dasgupta, Lall and Wheeler (2023) for a detailed description.
