The Tropospheric Monitoring Instrument (TROPOMI) is the single instrument on board the Copernicus Sentinel-5 Precursor (S-5P) satellite. S-5P is scheduled for a mission of seven years after launch and will monitor the composition of the atmosphere across the globe. It is a precursor mission for the Sentinel-5 missions within the ESA Copernicus program. 

The SWIR channel observes infrared light from 2305 to 2385 nm wavelength, with its main aims to retrieve the total columns of methane (CH4) and carbon-monoxide (CO). In order to provide the most reliable data, it is vital to monitor the health of the SWIR instrument and continuously review the calibration data used in processing the raw data. Results of this monitoring are published here. In addition, reports and technotes relevant to the SWIR calibration and health can be downloaded from this website.

Monitoring results for the UV, UVIS and NIR channels, as well as detailed information of the housekeeping data of the entire instrument can be found at the TROPOMI portal.

Disclaimer. Currently, this site is still underdevelopment. The website will be fully operation during the operational phase (E2). Any constructive feedback is greatly appreciated.
