Sentinel5PTROPOMI

Sentinel-5P TROPOMI is an instrument on board the European Space Agency's Sentinel-5 Precursor (Sentinel-5P) satellite, launched in October 2017. TROPOMI stands for TROPOspheric Monitoring Instrument. Its primary mission is to map atmospheric pollutants globally with unprecedented detail and accuracy. It observes Earth's atmosphere in the ultraviolet, visible, near-infrared, and shortwave infrared parts of the electromagnetic spectrum. This allows TROPOMI to measure the concentrations of various trace gases, including nitrogen dioxide (NO2), sulfur dioxide (SO2), ozone (O3), carbon monoxide (CO), methane (CH4), and aerosols. These measurements are crucial for understanding air quality, climate change, and atmospheric processes. The data collected by TROPOMI is freely available to researchers and the public, contributing significantly to scientific research and environmental monitoring efforts worldwide. Its high spatial resolution, of up to 3.5 by 5.5 kilometers, enables the identification of pollution sources at a city or even industrial level. This makes Sentinel-5P TROPOMI a vital tool for policy makers and environmental agencies in their efforts to combat air pollution and mitigate its impacts.
