Every verified plume, on the map

Each point is a real observation where a monitoring system verified a plume: EMIT granules confirmed by both IMEO and Carbon Mapper, and Sentinel-2 and Landsat 8/9 scenes annotated by IMEO MARS. Filter by sensor or country, and select a point for its details and for satellite image products preview. The plume bank has no geographic reference, so it is not on the map.

Plume bank / Single

methaneset-bank

Precomputed WRF-LES column enhancements across solar and wind geometry, at a reference rate of 3000 kg/h. A quality-filtered subset of the simulation grid: the raw 3D cubes are published separately as methaneset-bank-les, so new observation geometries can be projected.
