description Sentinel-5P Overview

Sentinel-5 Precursor (Sentinel-5P) is an environmental satellite operated by the European Space Agency (ESA) as part of the Copernicus Programme. Launched on a Rockot vehicle from Plesetsk Cosmodrome in 2017, it was designed to monitor global atmospheric composition. The satellite's primary instrument, Tropomi (TROPOspheric Monitoring Instrument), provides daily, high-resolution data on trace gases such as nitrogen dioxide, ozone, and methane. It bridges the data gap between the Envisat mission and the future Sentinel-5.

help Sentinel-5P FAQ

What does the P stand for in Sentinel-5P?

The P stands for Precursor, because the satellite was designed as a predecessor to the full Sentinel-5 atmospheric mission. Sentinel-5P is part of the European Union's Copernicus Earth observation programme.

When and where was Sentinel-5P launched?

Sentinel-5P launched on October 13, 2017, from the Plesetsk Cosmodrome in Russia. A Rockot launch vehicle carried the satellite into orbit.

What instrument does Sentinel-5P use to measure air pollution?

Its main instrument is TROPOMI, a spectrometer designed to map atmospheric trace gases. Measurements include nitrogen dioxide, ozone, formaldehyde, sulfur dioxide, methane, carbon monoxide, and aerosols.

How is Sentinel-5P different from a weather satellite?

Sentinel-5P focuses on atmospheric composition rather than producing ordinary cloud and temperature forecasts. Its TROPOMI data support air-quality monitoring, ozone studies, greenhouse-gas research, and climate analysis.
