Methanol (CH3OH), acetylene (C2H2), and propylene (C3H6) point-sources detected by the IASI infrared satellite instrument (2007-2023).

This dataset includes the super-sampled IASI 0.01° × 0.01° CH3OH, C2H2, C3H6, and SO2 HRI dataset in GeoTIFF format and the catalogue of identified and categorized point-sources of CH3OH, C2H2, and C3H6 in kml format. The oversampling, wind rotation and supersampling prorcedure and codes are available in the paper of Clarisse et al. (2019) at https://doi.org/10.5194/amt-12-5457-2019.
