These data were collected by a Riegl Q1560 scanning LiDAR and an ITRES CASI-1500 imaging spectrometer , both part of the NASA Airborne Snow Observatory (ASO), during two separate periods, February 8-9, 2016 and March 29-30, 2016. A previous September 2014 flight was used to obtain no-snow measurements used for deriving snow depth. The data are provided in GeoTIFF format.", "distribution": [{"@type": "dcat:Distribution", "downloadURL": "https://search.earthdata.nasa.gov/search?q=gpmasoolyx", "format": "BIN", "mediaType": "application/octet-stream"}, {"@type": "dcat:Distribution", "downloadURL": "http://dx.doi.org/10.5067/GPMGV/OLYMPEX/DATA101", "format": "HTML", "mediaType": "text/html"}, {"@type": "dcat:Distribution", "downloadURL": "http://olympex.atmos.washington.edu/", "format": "BIN", "mediaType": "application/octet-stream"}, {"@type": "dcat:Distribution", "downloadURL": "https://ghrc.earthdata.nasa.gov/browseui/#pub/gpmasoolyx__1/docs/gpmasoolyx_dataset.pdf", "format": "PDF", "mediaType": "application/pdf"}, {"@type": "dcat:Distribution", "downloadURL": "https://doi.org/10.1016/j.rse.2016.06.018", "format": "BIN", "mediaType": "application/octet-stream"}, {"@type": "dcat:Distribution", "downloadURL": "https://doi.org/10.1175/JHM-D-17-0076.1", "format": "BIN", "mediaType": "application/octet-stream"}, {"@type": "dcat:Distribution", "downloadURL": "https://dx.doi.org/10.1109/TGRS.2006.890412", "format": "BIN", "mediaType": "application/octet-stream"}, {"@type": "dcat:Distribution", "downloadURL": "https://dx.doi.org/10.1175/BAMS-D-16-0182.1", "format": "BIN", "mediaType": "application/octet-stream"}, {"@type": "dcat:Distribution", "downloadURL": "https://ghrc.nsstc.nasa.gov/home/field-campaigns/olympex", "format": "BIN", "mediaType": "application/octet-stream"}, {"@type": "dcat:Distribution", "downloadURL": "https://ghrc.nsstc.nasa.gov/home/about-ghrc/citing-ghrc-daac-data", "format": "BIN", "mediaType": "application/octet-stream"}, {"@type": "dcat:Distribution", "conformsTo": "http://www.isotc211.org/2005/gmi", "description": "The metadata's original source.", "downloadURL": "https://cmr.earthdata.nasa.gov/search/concepts/C1979129209-GHRC_DAAC.iso19115", "format": "ISO", "mediaType": "text/xml", "title": "Original Metadata"}], "identifier": "10.5067/GPMGV/OLYMPEX/LIDAR/DATA101", "keyword": ["earth-science-cryospheric-indicators-climate-indicators-snow-depth", "earth-science-land-use-land-cover-land-surface-land-use-land-cover-classification", "earth-science-topography-land-surface-terrain-elevation-digital-elevation-terrain-model-dem", "earth-science-visible-wavelengths-spectral-engineering-visible-imagery"], "license": "https://www.usa.gov/government-works", "modified": "2026-04-06", "programCode": ["026:000"], "publisher": {"@type": "org:Organization", "name": "NASA/MSFC/GHRC"}, "spatial": "[\"CARTESIAN\",[{\"WestBoundingCoordinate\":-124.185,\"NorthBoundingCoordinate\":48.0909,\"EastBoundingCoordinate\":-123.129,\"SouthBoundingCoordinate\":47.493}]]", "temporal": "2014-09-04/2016-03-30", "theme": ["Earth Science"], "title": "GPM Ground Validation Airborne Snow Observatory (ASO) OLYMPEX V1"}
