This collection spans from March 25, 2015 to October 29, 2017. CATS, which was launched on January 10, 2015, was a lidar remote sensing instrument that provided range-resolved profile measurements of atmospheric aerosols and clouds from the ISS. CATS was intended to operate on-orbit for up to three years. CATS provides vertical profiles at three wavelengths, orbiting between ~230 and ~270 miles above the Earth's surface at a 51-degree inclination with nearly a three-day repeat cycle. For the first time, scientists were able to study diurnal (day-to-night) changes in cloud and aerosol effects from space by observing the same spot on Earth at different times each day. CATS Level 2 Layer data products contain geophysical parameters and are derived from Level 1 data, at 60m vertical and 5km horizontal resolution.", "distribution": [{"@type": "dcat:Distribution", "downloadURL": "https://cats.gsfc.nasa.gov/media/docs/CATS_Data_Products_Catalog.pdf", "format": "PDF", "mediaType": "application/pdf"}, {"@type": "dcat:Distribution", "downloadURL": "https://asdc.larc.nasa.gov/documents/cats/quality_summaries/CATS_Release_Notes6_v2.pdf", "format": "PDF", "mediaType": "application/pdf"}, {"@type": "dcat:Distribution", "downloadURL": "https://asdc.larc.nasa.gov/project/CATS-ISS", "format": "BIN", "mediaType": "application/octet-stream"}, {"@type": "dcat:Distribution", "downloadURL": "https://asdc.larc.nasa.gov/citing-data", "format": "BIN", "mediaType": "application/octet-stream"}, {"@type": "dcat:Distribution", "downloadURL": "https://asdc.larc.nasa.gov/documents/cats/guide/CATS_ATBD.pdf", "format": "PDF", "mediaType": "application/pdf"}, {"@type": "dcat:Distribution", "downloadURL": "https://asdc.larc.nasa.gov/documents/cats/quality_summaries/CATS_Release_Notes6.pdf", "format": "PDF", "mediaType": "application/pdf"}, {"@type": "dcat:Distribution", "downloadURL": "https://cats.gsfc.nasa.gov/", "format": "BIN", "mediaType": "application/octet-stream"}, {"@type": "dcat:Distribution", "downloadURL": "https://cats.gsfc.nasa.gov/data/browse/", "format": "BIN", "mediaType": "application/octet-stream"}, {"@type": "dcat:Distribution", "downloadURL": "https://search.earthdata.nasa.gov/search/granules?p=C1577484442-LARC_ASDC", "format": "BIN", "mediaType": "application/octet-stream"}, {"@type": "dcat:Distribution", "downloadURL": "https://doi.org/10.5067/ISS/CATS/L1B_D-M7.2-V3-00", "format": "HTML", "mediaType": "text/html"}, {"@type": "dcat:Distribution", "downloadURL": "https://asdc.larc.nasa.gov/documents/cats/guide/CATS_Data_Products_Catalog_R7.0.pdf", "format": "PDF", "mediaType": "application/pdf"}, {"@type": "dcat:Distribution", "downloadURL": "https://asdc.larc.nasa.gov/documents/cats/guide/CATS_Data_Products_Catalog_R6.0.pdf", "format": "PDF", "mediaType": "application/pdf"}, {"@type": "dcat:Distribution", "downloadURL": "https://earthobservatory.nasa.gov/images/84400/dust-and-clouds-dance-over-the-sahara", "format": "BIN", "mediaType": "application/octet-stream"}, {"@type": "dcat:Distribution", "downloadURL": "https://earthobservatory.nasa.gov/images/84214/blue-marble-eastern-hemisphere", "format": "BIN", "mediaType": "application/octet-stream"}, {"@type": "dcat:Distribution", "downloadURL": "https://earthobservatory.nasa.gov/images/86286/nighttime-view-of-raung-volcanic-plume", "format": "BIN", "mediaType": "application/octet-stream"}, {"@type": "dcat:Distribution", "downloadURL": "https://earthobservatory.nasa.gov/images/86218/a-slice-of-cirrus", "format": "BIN", "mediaType": "application/octet-stream"}, {"@type": "dcat:Distribution", "downloadURL": "https://asdc.larc.nasa.gov/data/CATS/L1B_D-M7.2-V3-00/", "format": "BIN", "mediaType": "application/octet-stream"}, {"@type": "dcat:Distribution", "downloadURL": "https://opendap.larc.nasa.gov/opendap/CATS/L1B_D-M7.2-V3-00/contents.html", "format": "HTML", "mediaType": "text/html"}, {"@type": "dcat:Distribution", "conformsTo": "http://www.isotc211.org/2005/gmi", "description": "The metadata's original source.", "downloadURL": "https://cmr.earthdata.nasa.gov/search/concepts/C1577484442-LARC_ASDC.iso19115", "format": "ISO", "mediaType": "text/xml", "title": "Original Metadata"}], "identifier": "10.5067/ISS/CATS/L1B_D-M7.2-V3-00", "keyword": ["earth-science-aerosols-atmosphere", "earth-science-aerosols-atmosphere-aerosol-backscatter", "earth-science-aerosols-atmosphere-aerosol-optical-depth-thickness", "earth-science-clouds-atmosphere", "earth-science-clouds-atmosphere-cloud-properties-cloud-height", "earth-science-clouds-atmosphere-cloud-properties-cloud-vertical-distribution"], "license": "https://www.usa.gov/government-works", "modified": "2026-04-06", "programCode": ["026:000"], "publisher": {"@type": "org:Organization", "name": "NASA/LARC/SD/ASDC"}, "spatial": "[\"CARTESIAN\",[{\"Boundary\":{\"Points\":[{\"Latitude\":-52,\"Longitude\":-180},{\"Latitude\":-52,\"Longitude\":180},{\"Latitude\":52,\"Longitude\":180},{\"Latitude\":52,\"Longitude\":-180},{\"Latitude\":-52,\"Longitude\":-180}]}}]]", "temporal": "2015-03-25/2017-10-29", "theme": ["Earth Science"], "title": "CATS-ISS Level 1B Day Mode 7.2 Version 3-00"}
