The TROPOMI instrument aboard the SENTINEL-5P space craft is a nadir-viewing, imaging spectrometer covering wavelength bands between the ultraviolet and the shortwave infra-red. TROPOMI's purpose is to measure atmospheric properties and constituents. It is contributing to monitoring air quality and providing critical information to services and decision makers.
The instrument uses passive remote sensing techniques by measuring the Top Of Atmosphere (TOA) solar radiation reflected by and radiated from the earth and its atmosphere. The four spectrometers of TROPOMI cover the ultraviolet (UV), visible (VIS), Near Infra-Red (NIR) and Short Wavelength Infra-Red (SWIR) domains of the electromagnetic spectrum, allowing operational retrieval of the following trace gas constituents: Ozone (O3), Nitrogen Dioxide (NO2), Sulfur Dioxide (SO2), Formaldehyde (HCHO), Carbon Monoxide (CO) and Methane (CH4).
Local equator crossing time of the ascending node is 13:30. Daily observations are binned onto a regular latitude-longitude grid.
Within INPULS, innovative algorithms and processors for the generation of Level 3 and Level 4 products, improved data discovery and access technologies as well as server-side analytics for the users are developed.
Period: February 2018 - ongoing
Horizontal resolution: 0.09 degrees x 0.09 degrees
Attention: Since 01.08.2023, the S5P L3 data has been generated with the new UMAS: 4.1.0 processor. Therefore, only this data is available in the WMS. The "old" data are still available in the download service until July 31, 2023. From 01.08.2023 the new data is available.
