There is one-to-one correspondence between this product and the dark current master data files, the difference is the working product data have been filtered.\n\nThe data were originally created on IBM 360 machines and archived on magnetic tapes. The data have been restored from the tapes and are now archived on disk in their original IBM binary file format. Each file contains about one orbit of data from the nighttime descending node. The data files consist of 140 4-byte word records which are blocked with up to 25 records. The average size of an orbit file is 375 kB.\n\nThis product was previously available from the NSSDC with the identifier ESAC-00054 (old ID 70-025A-05I).", "distribution": [{"@type": "dcat:Distribution", "downloadURL": "https://docserver.gesdisc.eosdis.nasa.gov/public/project/Images/BUVN4L1DCW_001.png", "format": "PNG", "mediaType": "image/png", "title": "Get a related visualization"}, {"@type": "dcat:Distribution", "description": "Access the dataset landing page from the GES DISC website.", "downloadURL": "https://disc.gsfc.nasa.gov/datacollection/BUVN4L1DCW_001.html", "format": "HTML", "mediaType": "text/html", "title": "This dataset's landing page"}, {"@type": "dcat:Distribution", "description": "Access the data via HTTPS.", "downloadURL": "https://acdisc.gesdisc.eosdis.nasa.gov/data/Nimbus4_BUV_Level1/BUVN4L1DCW.001/", "format": "HTML", "mediaType": "text/html", "title": "Download this dataset through a directory map"}, {"@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=BUVN4L1DCW", "format": "HTML", "mediaType": "text/html", "title": "Download this dataset through Earthdata Search"}, {"@type": "dcat:Distribution", "description": "README Document", "downloadURL": "https://acdisc.gesdisc.eosdis.nasa.gov/data/Nimbus4_BUV_Level1/BUVN4L1DCW.001/doc/README.BUVN4L1DCS.001.pdf", "format": "PDF", "mediaType": "application/pdf", "title": "View this dataset's read me document"}, {"@type": "dcat:Distribution", "description": "Nimbus 4 BUV User's Guide", "downloadURL": "https://docserver.gesdisc.eosdis.nasa.gov/repository/Mission/Nimbus/3.3_Product_Documentation/3.3.5_Product_Quality/N4_BUV_UsersGuide_19780013751.pdf", "format": "PDF", "mediaType": "application/pdf", "title": "View this dataset's user's guide"}, {"@type": "dcat:Distribution", "description": "Nimbus 4 User's Guide", "downloadURL": "https://docserver.gesdisc.eosdis.nasa.gov/repository/Mission/Nimbus/3.3_Product_Documentation/3.3.5_Product_Quality/NimbusIVUG.pdf", "format": "PDF", "mediaType": "application/pdf", "title": "View this dataset's user's guide"}, {"@type": "dcat:Distribution", "description": "Nimbus 4 Data Catalog", "downloadURL": "https://docserver.gesdisc.eosdis.nasa.gov/repository/Mission/Nimbus/3.3_Product_Documentation/3.3.5_Product_Quality/DataCatalogNimbus4.tar.gz", "format": "GZ", "mediaType": "application/gzip", "title": "View documentation related to this dataset"}, {"@type": "dcat:Distribution", "description": "BUV Dark Current Study: Master Data and Working Data", "downloadURL": "https://docserver.gesdisc.eosdis.nasa.gov/repository/Mission/Nimbus/3.4_Mission_Calibration/3.4.2_Calibration_Data/N4_BUV_DCS_Format.pdf", "format": "PDF", "mediaType": "application/pdf", "title": "View documentation related to this dataset"}, {"@type": "dcat:Distribution", "description": "BUV Dark Current Study: Data Filtering", "downloadURL": "https://docserver.gesdisc.eosdis.nasa.gov/repository/Mission/Nimbus/3.4_Mission_Calibration/3.4.1_Calibration_Method/N4_BUV_DarkCurrent_DataFiltering.pdf", "format": "PDF", "mediaType": "application/pdf", "title": "View documentation related to this dataset"}, {"@type": "dcat:Distribution", "description": "N4 BUV Inventory", "downloadURL": "https://docserver.gesdisc.eosdis.nasa.gov/public/project/Nimbus/N4_BUV_Inventory.xlsx", "format": "HTML", "mediaType": "text/html", "title": "View documentation related to this dataset"}], "identifier": "C1273652163-GES_DISC", "issued": "2015-12-03", "keyword": ["earth-science", "spectral-engineering", "ultraviolet-wavelengths"], "landingPage": "https://cmr.earthdata.nasa.gov:443/search/concepts/C1273652163-GES_DISC.html", "language": ["en-US"], "modified": "2025-04-01", "programCode": ["026:001"], "publisher": {"@type": "org:Organization", "name": "NASA/GSFC/SED/ESD/GCDC/GESDISC"}, "spatial": "-180.0 -80.1 180.0 80.1", "temporal": "1970-04-10T00:00:00Z/1971-12-16T23:59:59.999Z", "theme": ["Nimbus", "geospatial"], "title": "BUV/Nimbus-4 Dark Current Study Working Data V001 (BUVN4L1DCW) at GES DISC"}
