Brightness temperatures are processed to estimate the wet troposphere content, atmospheric attenuation to backscatter, cloud liquid water, water vapor content, and wind speed coincident with each range measurement from the nadir altimeter and applied to correct for altimeter range delays caused by atmospheric effects. SWOT is a joint mission between NASA and CNES that launched on December 16, 2022. It aims to measure ocean surface topography with unprecedented resolution and accuracy, as well as map inland water bodies globally.\r\nThe interim radiometer dataset consists of discrete measurements along two tracks located approximately 30-km to the left and right of the satellite nadir. The data were processed using the Medium-accuracy (preliminary) Orbit Ephemeris (MOE) with preliminary calibrations applied. They are distributed as one file per half-orbit in netCDF4 file format with a nominal latency of < 1.5 days.", "distribution": [{"@type": "dcat:Distribution", "description": "Access the data via HTTP", "downloadURL": "https://oco2.gesdisc.eosdis.nasa.gov/data/OCO3_DATA/OCO3_L2_IMAPDOAS.11/", "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://oco2.gesdisc.eosdis.nasa.gov/opendap/OCO3_L2_IMAPDOAS.11/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/OCO3_L2_IMAPDOAS_11.html", "format": "HTML", "mediaType": "text/html", "title": "This dataset's landing page"}, {"@type": "dcat:Distribution", "description": "OCO Documentation", "downloadURL": "https://disc.gsfc.nasa.gov/information/documents?title=OCO-2+Documents", "format": "HTML", "mediaType": "text/html", "title": "View documentation related to this dataset"}, {"@type": "dcat:Distribution", "description": "OCO-3 Data Gaps", "downloadURL": "https://disc.gsfc.nasa.gov/information/documents?title=OCO-3+Known+Data+Issues", "format": "HTML", "mediaType": "text/html", "title": "View documentation related to this dataset"}, {"@type": "dcat:Distribution", "description": "OCO-3 Data Quality Statement", "downloadURL": "https://docserver.gesdisc.eosdis.nasa.gov/public/project/OCO/OCO3_L2_DQ_Statement_v10.pdf", "format": "PDF", "mediaType": "application/pdf", "title": "View documentation related to this dataset"}, {"@type": "dcat:Distribution", "description": "OCO-3 Project Home Page", "downloadURL": "https://ocov3.jpl.nasa.gov/", "format": "HTML", "mediaType": "text/html", "title": "The dataset's project home page"}, {"@type": "dcat:Distribution", "description": "Publications from the Science Team", "downloadURL": "https://ocov3.jpl.nasa.gov/science/publications/", "format": "HTML", "mediaType": "text/html", "title": "View documentation related to this dataset"}, {"@type": "dcat:Distribution", "description": "README document", "downloadURL": "https://docserver.gesdisc.eosdis.nasa.gov/public/project/OCO/README.OCO2.pdf", "format": "PDF", "mediaType": "application/pdf", "title": "View this dataset's read me document"}, {"@type": "dcat:Distribution", "description": "Software Interface Specification", "downloadURL": "https://docserver.gesdisc.eosdis.nasa.gov/public/project/OCO/SDOS_SIS_L2Fluorescence.V6.pdf", "format": "PDF", "mediaType": "application/pdf", "title": "View the primary investigator's documentation for this dataset"}, {"@type": "dcat:Distribution", "description": "This software (NASA NTR-49044) retrieves a set of atmospheric/surface/instrument parameters from a simultaneous fit to spectra from multiple absorption bands.
