Sentinel-5P Cloud Top Height

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

About Cloud Top Height

This online platform uses data from the Copernicus Sentinel-5P satellite and shows the daily cloud top height across the globe, as well as monthly, seasonal and yearly moving averages.

The TROPOMI instrument, single payload onboard Sentinel-5 Precursor, retrieves operationally the most important quantities for cloud correction of satellite trace gas retrievals: cloud fraction, cloud optical thickness (albedo), and cloud-top pressure (height). Cloud parameters from TROPOMI are not only used for enhancing the accuracy of trace gas retrievals, but also to extend the satellite data record of cloud information derived from oxygen A-band measurements initiated with GOME.

The cloud top height map shown here is measured by the Tropomi instrument on the Sentinel 5 Precursor satellite. The Tropomi measurements are performed in the visible part of the spectrum. More information on the Tropomi aerosol index measurements and quality assessment can be found in the Product Readme file.

About this S5P-PAL map

The maps shown on this site have been based on collection 3 of the Sentinel-5P Cloud Level-2 products (L2__CLOUD_), available from the Copernicus Data Space Ecosystem. The readme file of this product can be found here.

The Copernicus Sentinel-5P cloud top height measurements were first filtered according to the recommendation in the Product Readme file (only data with a qa_value > 0.5 was used). Then the measurements are mapped on a fixed latitude-longitude grid of 8193 x 16385 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.
