TROPOMI (TROPOspheric Monitoring Instrument)

Missions → Sentinel-5P (Precursor) (Operational)

Nadir-viewing UV-VIS-NIR-SWIR pushbroom imaging spectrometer aboard Sentinel-5P for daily global atmospheric composition measurements, including ozone, NO2, SO2, CO, CH4, formaldehyde, aerosols, and clouds.

Sensor

TROPOMI is the TROPOspheric Monitoring Instrument flown on Sentinel-5P for daily global atmospheric composition observations ^[1]^[2]. It is a nadir-viewing passive optical pushbroom imaging spectrometer spanning ultraviolet, visible, near-infrared, and shortwave-infrared wavelengths from 270 to 2385 nm ^[1]^[2]. The instrument separates its measurements into UV-VIS, NIR, and SWIR channels, with about 2600 spectral samples across the combined system ^[1].

For buyers evaluating atmospheric trace-gas coverage, TROPOMI is built around broad daily daylight mapping rather than narrow tasking. Its pushbroom swath is about 2600 km, supporting daily global coverage from the Sentinel-5P orbit ^[1]^[2]. Near nadir, non-SWIR products are sampled at about 7 x 3.5 km, while SWIR products are about 7 x 7 km ^[1]. The measurement set supports ozone, nitrogen dioxide, sulphur dioxide, carbon monoxide, methane, formaldehyde, aerosol, and cloud products ^[2]^[3].

The instrument was designed and built by Airbus Netherlands, TNO, and SRON.^[3]. TROPOMI is suited to users who need global atmospheric screening, emissions monitoring, and continuity with operational trace-gas products from a public Sentinel mission, with product interpretation tied to the spectral channel and ground-pixel differences between UV-VIS, NIR, and SWIR retrievals ^[1]^[2].

UV-VIS nadir spectroscopyvia Sentinel-5P (Precursor)
TROPOMI products include tropospheric NO2 and SO2 column retrievals from nadir UV-VIS observations.
SWIR absorption - global screeningvia Sentinel-5P (Precursor)
TROPOMI includes a SWIR channel at 2305-2385 nm and retrieves CO and CH4 using shortwave-infrared absorption.
