Sentinel 5

The Copernicus Sentinel-5 Precursor mission, focused on monitoring Earth's atmosphere, consists of a single satellite equipped with the TROPOspheric Monitoring Instrument (TROPOMI).

This mission bridges the gap in global atmospheric data between the retired ENVISAT and AURA missions and the upcoming Sentinel-5 mission. TROPOMI's main objective is to deliver daily global observations of key atmospheric components that are essential for monitoring air quality, tracking the ozone layer, and studying climate change.

Level 2 data products include total column measurements for ozone, sulfur dioxide, nitrogen dioxide, carbon monoxide, and formaldehyde, as well as tropospheric ozone columns, vertical ozone profiles, and information on clouds and aerosols. Since April 2018, Level 2 data has been available to enhance air quality forecasts and monitor atmospheric composition. COPSI platform contains ozone data.

The Sentinel-5P Level 2 O3 data refers to processed and derived datasets obtained from the Sentinel-5P satellite mission that focuses on measuring and analyzing the concentration and distribution of ozone in the Earth’s atmosphere. Researchers and scientists utilize this data for various purposes, that includes monitoring and assessing ozone depletion, particularly in regions like the polar areas, where the ozone layer is crucial. Additionally, the data aids in air quality monitoring, enabling the evaluation of ozone pollution control measures and understanding of pollution sources.
