Sentinel-5P Aerosol Optical Depth

This map is based on PRE-OPERATIONAL Sentinel-5P L2 products. It may get updated at any point without advance notice, and long term availability is not guaranteed.

About Aerosol Optical Depth

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

The Sentinel-5P Aerosol Optical Thickness (AOT) product was designed to monitor the daily global spatial distribution of aerosols in the Earth’s atmosphere. Together with the S5P Aerosol Index and S5P Aerosol Layer Height product it constitutes the suite of global aerosol products that can be used to monitor and analyse the spatial and temporal distribution of naturally and anthropogenically emitted aerosols such desert dust plumes, volcanic ash, sea salt, industrial pollution, etc.

About this S5P-PAL map

The maps shown on this site have been based on the latest pre-operational Sentinel-5P Aerosol Optical Thickness Level-2 products (L2__AER_OT), available from the S5P-PAL data portal . The readme file of this product can be found here.

The Copernicus Sentinel-5P aerosol optical thickness measurements were first filtered based on 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.
