This variable has a significant bias due to a conversion error: the molecular weight of carbon dioxide (CO2, 44.01 g/mol) was used instead of carbon monoxide (CO, 28.01 g/mol). To correct, simply multiply \u201cco_mmr_midtrop\u201d by 28.01/44.01. Alternatively, derive a profile of mass mixing ratio from scratch using the retrieved column density values (\u201cmol_lay/co_mol_lay\u201d) in the Level 2 files. For further questions or concerns please contact the Sounder SIPS at: sounder.sips@jpl.nasa.gov\n\nThe CLIMCAPS (Community Long-term Infrared Microwave Coupled Product System) algorithm is used to analyze data from the Cross-track Infrared Sounder/Advanced Technology Microwave Sounder (CrIS/ATMS) instruments, also known as CrIMSS (Cross-track Infrared and Microwave Sounding Suite). The CrIS/ATMS instruments used for this product are on board the Suomi National Polar-orbiting Partnership (SNPP) platform and use the Full Spectral Resolution (FSR) data. The CrIS instrument is a Fourier transform spectrometer with a total of 2211 FSR infrared sounding channels covering the longwave (645-1095 cm-1), midwave (1210-1750 cm-1), and shortwave (2000-2550 cm-1) spectral regions. The ATMS instrument  is a cross-track scanner with 22 channels in spectral bands from 23 GHz through 183 GHz.\n \nThe CLIMCAPS algorithm uses an Optimal Estimation methodology and uses an a-priori first guess to start the process. A CLIMCAPS sounding is comprised of a set of parameters that characterizes the full atmospheric state and includes a variety of geophysical parameters derived from the CrIMSS data. These include surface temperature and infrared emissivity; full atmosphere profiles of temperature, water vapor and ozone; infrared effective cloud top characteristics; carbon monoxide, methane, carbon dioxide, sulfur dioxide, nitrous oxide, and nitric acid.\n \nThis daily one degree latitude by one degree longitude level-3 product starts with level-2 retrieval products with QC values of 0 (best), 1 (good), and 2 (don't use) which are provided for each variable. Comprehensive QC accepts a retrieval if the profile is good to the surface and ensures consistent analysis across all levels and variables.", "distribution": [{"@type": "dcat:Distribution", "description": "Access the data via HTTPS.", "downloadURL": "https://sounder.gesdisc.eosdis.nasa.gov/data/SNPP_Sounder_Level3/SNDRSNIML3CDCCP.2", "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://sounder.gesdisc.eosdis.nasa.gov/opendap/SNPP_Sounder_Level3/SNDRSNIML3CDCCP.2/", "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/SNDRSNIML3CDCCP_2.html", "format": "HTML", "mediaType": "text/html", "title": "This dataset's landing page"}, {"@type": "dcat:Distribution", "description": "CLIMCAPS ATBD", "downloadURL": "https://docserver.gesdisc.eosdis.nasa.gov/public/project/Sounder/CLIMCAPS.V2.ATBD.pdf", "format": "PDF", "mediaType": "application/pdf", "title": "View this dataset's algorithm theoretical basis document"}, {"@type": "dcat:Distribution", "description": "CLIMCAPS Product User Guide:File Format and Definition", "downloadURL": "https://docserver.gesdisc.eosdis.nasa.gov/public/project/Sounder/CLIMCAPS.L3.V2.README.pdf", "format": "PDF", "mediaType": "application/pdf", "title": "View this dataset's read me document"}, {"@type": "dcat:Distribution", "description": "Sample plot of CrIS/ATMS Level 3 daily surface skin temperature (K).", "downloadURL": "https://docserver.gesdisc.eosdis.nasa.gov/public/project/Images/SNDRSNIML3CDCCP_2.png", "format": "PNG", "mediaType": "image/png", "title": "Get a related visualization"}, {"@type": "dcat:Distribution", "description": "Search results for publications that cite this dataset by its DOI.", "downloadURL": "https://scholar.google.com/scholar?q=10.5067%2FL98ZW61HG7TI", "format": "HTML", "mediaType": "text/html", "title": "Google Scholar search results"}, {"@type": "dcat:Distribution", "description": "Search the Earthdata website", "downloadURL": "https://search.earthdata.nasa.gov/search?q=SNDRSNIML3CDCCP+2", "format": "HTML", "mediaType": "text/html", "title": "Download this dataset through Earthdata Search"}], "identifier": "C1692982085-GES_DISC", "issued": "2015-11-02", "keyword": ["air-quality", "altitude", "atmosphere", "atmospheric-chemistry", "atmospheric-pressure", "atmospheric-radiation", "atmospheric-temperature", "atmospheric-water-vapor", "clouds", "earth-science", "land-surface", "ocean-temperature", "oceans", "precipitation", "surface-radiative-properties", "surface-thermal-properties"], "landingPage": "https://doi.org/10.5067/L98ZW61HG7TI", "language": ["en-US"], "modified": "2025-03-31", "programCode": ["026:001"], "publisher": {"@type": "org:Organization", "name": "Not provided"}, "references": ["https://doi.org/10.1016/S0022-4073(97)00169-6", "https://doi.org/10.1029/2005/JD007020", "https://doi.org/10.1109/TGRS.2002.808236", "https://doi.org/10.1109/TGRS.2012.2220369", "https://doi.org/10.3390/rs11101227", "https://doi.org/10.5194/amt-13-4437-2020"], "spatial": "-180.0 -90.0 180.0 90.0", "temporal": "2015-11-02T00:00:00Z/2023-02-28T00:00:00Z", "theme": ["SUOMI-NPP", "geospatial"], "title": "Sounder SIPS: Suomi NPP CrIMSS Level 3 Comprehensive Quality Control Gridded Daily CLIMCAPS Full Spectral Resolution V2 at GES DISC"}
