SENTINEL-5 Overview

SENTINEL-5, launched in 2020,  is ESAs fifth mission as part of the Copernicus Programme.  Like its predecessor SENTINEL-4, it is focused on monitoring the climate and air quality – providing data on a wide range of areas, from pollutants such as NO2 to the state of the Ozone layer.

S4 v S-5

One of the most obvious differences between S-4 and S-5 is the enormous difference in their orbit. SENTINEL-4 orbits at nearly 36,000km (Geostationary or geosynchronous equatorial orbit GEO). however S-5  orbits at 800km. The two missions have similar instruments onboard, with the former using 3 bands and the latter using 7 bands (details below).

SENTINEL-5 – Technical Details

The main areas it will be monitoring are:

O3, NO2, SO2, HCHO, CHOCHO

It can also provide data on CO, CH4, and stratospheric O3 with daily global coverage for climate, air quality, and ozone/surface UV applications.

SENTINEL-5  Spectral bands:

UV-1 (270-300nm), UV-2 (300-370nm), VIS (370-500nm), NIR-1 (685-710nm), NIR-2 (745-773nm), SWIR-1 (1590-1675nm) and SWIR-3 (2305-2385nm).
