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

The TROPOMI Aerosol Layer Height product focuses on retrieval of vertically localised aerosol layers in the free troposphere, such as desert dust, biomass burning aerosol, or volcanic ash plumes. The height of such layers is retrieved for cloud-free conditions. Height information for aerosols in the free troposphere is particularly important for aviation safety. Scientific applications include radiative forcing studies, long-range transport modelling and studies of cloud formation processes. Aerosol height information also helps to interpret the UV Aerosol Index (UVAI) in terms of aerosol absorption as the index is strongly height-dependent.
The aerosol layer 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.
