Short summary

TROPOMI aboard Sentinel-5P satellite provides methane (CH₄) measurements with exceptional temporal and spatial resolution. The study describes a series of improvements developed to retrieve CH₄ from TROPOMI. The updated CH₄ product features (among others) a more accurate a posteriori correction derived independently of any reference data. The validation of the improved data product shows good agreement with ground-based and satellite measurements, which highlights the quality of the TROPOMI CH₄.
