Older versions will no longer be available and are superseded by Version 11r.\n\nThe Orbiting Carbon Observatory is the first NASA mission designed to collect space-based measurements of atmospheric carbon dioxide with the precision, resolution, and coverage needed to characterize the processes controlling its buildup in the atmosphere. The OCO-3 project uses the LEOStar-2 spacecraft that carries a single instrument. It incorporates three high-resolution spectrometers that make coincident measurements of reflected sunlight in the near-infrared CO2 near 1.61 and 2.06 micrometers and in molecular oxygen (O2) A-Band at 0.76 micrometers. The three spectrometers have different characteristics and are calibrated independently. Their raw data numbers (DN) are delivered correlated in time to the Level 1B process as Level 1A products. Each band has 1016 spectral elements, although some are masked out in the L2 retrieval.This product is the input to the Level 1B process. It is depacketized raw data formatted into a standard granularity with calibrated engineering data (for both science and calibration observations), in the Sample Mode of operation.This is the retrospective processing where the calibration data is estimated from the full timeseries of data (before, during, and after the measurements), and is expected to be of slightly higher quality.", "distribution": [{"@type": "dcat:Distribution", "description": "Access the data via HTTP.", "downloadURL": "https://oco2.gesdisc.eosdis.nasa.gov/data/OCO3_DATA/OCO3_L1aIn_Pixel.11r/", "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_L1aIn_Pixel.11r/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_L1aIn_Pixel_11r.html", "format": "HTML", "mediaType": "text/html", "title": "This dataset's landing page"}, {"@type": "dcat:Distribution", "description": "Level 1A Software Interfase Specification.", "downloadURL": "https://docserver.gesdisc.eosdis.nasa.gov/public/project/OCO/SDOS_SIS_L1aIn.V7.pdf", "format": "PDF", "mediaType": "application/pdf", "title": "View the primary investigator's documentation for this dataset"}, {"@type": "dcat:Distribution", "description": "OCO-2 Data Gaps", "downloadURL": "https://disc.gsfc.nasa.gov/information/documents?title=OCO+Known+Data+Issues", "format": "HTML", "mediaType": "text/html", "title": "View documentation related to this dataset"}, {"@type": "dcat:Distribution", "description": "OCO-2 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 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": "Subset recipe using OPeNDAP", "downloadURL": "https://disc.gsfc.nasa.gov/information/howto?title=How+to+download+a+spatial+and+variable+subset+of+Level+1B+data+using+OPeNDAP", "format": "HTML", "mediaType": "text/html", "title": "View this dataset's how-to documentation"}, {"@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.
