Ethylene (C2H4) point-sources detected by the IASI infrared satellite instrument (2008-2020).

This dataset includes the super-sampled IASI 0.01° × 0.01° C₂H₄ HRI dataset in GeoTIFF format and the catalogue of the identified and categorized C₂H₄ point-sources in kml format (C2H4_HRI_pointsources.zip). It also includes the super-sampled IASI C₂H₄ total columns used to calculate the emission fluxes from the analyzed point-sources (C2H4_column_pointsources.zip) and the source data needed to reproduce the figures (C2H4_SourceData.zip). The code to calculate the C₂H₄ HRI from IASI spectra and to retrieve the C₂H₄ total columns is provided (C2H4_codes.zip), along with the artificial neural network used for the retrievals, instructions and example data. The codes of the oversampling, wind rotation and supersampling are available in the paper of Clarisse et al. (2019) at https://doi.org/10.5194/amt-12-5457-2019.
