Sentinel-5P Total Column CH4

This map is based on OPERATIONAL Sentinel-5P L2 products.

About Total Column CH4

This online platform uses data from the Copernicus Sentinel-5P satellite and shows the averaged methane concentrations across the globe — using weekly averaged maps.

The methane map shown here is measured by the Tropomi instrument on the Sentinel 5 Precursor satellite. More information on the Tropomi CH4 measurements and quality assessment can be found in the Product Readme file.

Data gaps are visible based on the product quality filtering and the fact that over the sea only measurements for sun-glint situations are being provided.

About this S5P-PAL map

The maps shown on this site have been based on collection 3 of the Sentinel-5P Methane Level-2 products (L2__CH4___), available from the Copernicus Data Space Ecosystem. The readme file of this product can be found here.

The Copernicus Sentinel-5P CH4 measurements were first filtered according to the recommendation in the Product Readme file (only data with a qa_value > 0.50 was used). Then the measurements are mapped on a fixed latitude-longitude grid of 4096 x 8192 pixels. The grid is turned into an EPSG:4326 geotiff file using the appropriate color scale, which is again turned into an EPSG:3857 tile map.

The maps and underlying Level-3 gridded data files were generated by S5P-PAL. The Level-3 data can be downloaded from the S5P-PAL Data Portal, or directly via the download button below the map.

This service is provided as part of the Sentinel-5P Product Algorithm Laboratory (S5P-PAL)
and contains modified Copernicus Sentinel data processed by S[&]T.
