The sole payload on Sentinel-5P is the TROPOspheric Monitoring Instrument (TROPOMI), which is a nadir-viewing 108 degree Field-of-View push-broom grating hyperspectral spectrometer, covering the wavelength of ultraviolet-visible (UV-VIS, 270nm to 495nm), near infrared (NIR, 675nm to 775nm), and shortwave infrared (SWIR, 2305nm-2385nm). Sentinel-5P is the first of the Atmospheric Composition Sentinels and is expected to provide measurements of ozone, NO2, SO2, CH4, CO, formaldehyde, aerosols and cloud at high spatial, temporal and spectral resolutions.\n\nThe TROPOMI retrieval of total and tropospheric NO2, is based on the DOMINO approach, a DOAS retrieval, a pre-calculated air-mass factor (AMF) look-up table, and a data assimilation/chemistry transport model for the separation of the stratospheric and tropospheric contributions to the NO2 column. It also include many retrieval developments of the European Quality Assurance for Essential Climate Variables (QA4ECV) project.", "distribution": [{"@type": "dcat:Distribution", "description": "Access the data via HTTPS.", "downloadURL": "https://tropomi.gesdisc.eosdis.nasa.gov/data/S5P_TROPOMI_Level2/S5P_L2__NO2___.1", "format": "HTML", "mediaType": "text/html", "title": "Download this dataset through a directory map"}, {"@type": "dcat:Distribution", "description": "Access the data via the OPeNDAP protocol.", "downloadURL": "https://tropomi.gesdisc.eosdis.nasa.gov/opendap/S5P_TROPOMI_Level2/S5P_L2__NO2___.1/contents.html", "format": "HTML", "mediaType": "text/html", "title": "Use OPeNDAP to access the dataset's data"}, {"@type": "dcat:Distribution", "description": "Access the dataset landing page from the GES DISC website.", "downloadURL": "https://disc.gsfc.nasa.gov/datacollection/S5P_L2__NO2____1.html", "format": "HTML", "mediaType": "text/html", "title": "This dataset's landing page"}, {"@type": "dcat:Distribution", "description": "S5P TROPOMI Data Collection Summary", "downloadURL": "https://disc.gsfc.nasa.gov/information/glossary?title=Sentinel-5P", "format": "HTML", "mediaType": "text/html", "title": "View this dataset's product history"}, {"@type": "dcat:Distribution", "description": "Search results for publications that cite this dataset by its DOI.", "downloadURL": "https://scholar.google.com/scholar?q=10.5270%2FS5P-s4ljg54", "format": "HTML", "mediaType": "text/html", "title": "Google Scholar search results"}, {"@type": "dcat:Distribution", "description": "Use the Earthdata Search to find and retrieve data sets across multiple data centers.", "downloadURL": "https://search.earthdata.nasa.gov/search?q=S5P_L2__NO2____1", "format": "HTML", "mediaType": "text/html", "title": "Download this dataset through Earthdata Search"}, {"@type": "dcat:Distribution", "downloadURL": "https://docserver.gesdisc.eosdis.nasa.gov/public/project/Images/S5P_OFFL_L2__NO2____1.png", "format": "PNG", "mediaType": "image/png", "title": "Get a related visualization"}], "identifier": "C1442068511-GES_DISC", "issued": "2017-05-05", "keyword": ["atmosphere", "atmospheric-chemistry", "earth-science"], "landingPage": "https://doi.org/10.5270/S5P-s4ljg54", "language": ["en-US"], "modified": "2025-07-17", "programCode": ["026:001"], "publisher": {"@type": "org:Organization", "name": "NASA/GSFC/SED/ESD/GCDC/GESDISC"}, "spatial": "-180.0 -90.0 180.0 90.0", "temporal": "2018-04-30T00:41:24Z/2022-01-17T00:00:00Z", "theme": ["Sentinel-5P", "geospatial"], "title": "Sentinel-5P TROPOMI Tropospheric NO2 1-Orbit L2 7km x 3.5km V1 (S5P_L2__NO2___) at GES DISC"}
