GCPEx addressed shortcomings in the GPM snowfall retrieval algorithm by collecting microphysical properties, associated remote sensing observations, and coordinated model simulations of precipitating snow. These data sets were collected to aid in the achievement of the over arching goal of GCPEx which is to characterize the ability of multi-frequency active and passive microwave sensors to detect and estimate falling snow. The data is available only for February 20, 2012, a clear-air flight day. DC-8 Camera nadir data may be useful for determining snow cover and lake ice cover for emissivity studies. The dataset also includes, for convenience and reproducibility, aircraft navigation information and ground temperatures to aid in emissivity retrievals.", "distribution": [{"@type": "dcat:Distribution", "description": "Search results for publications that cite this dataset by its DOI.", "downloadURL": "https://scholar.google.com/scholar?q=10.5067%2FGPMGV%2FGCPEX%2FCAMERA%2FDATA102", "format": "HTML", "mediaType": "text/html", "title": "Google Scholar search results"}, {"@type": "dcat:Distribution", "description": "Files may be downloaded directly to your workstation from this link", "downloadURL": "https://search.earthdata.nasa.gov/search?q=gpmncamdc8gcpex", "format": "HTML", "mediaType": "text/html", "title": "Download this dataset"}, {"@type": "dcat:Distribution", "description": "Sample browse image", "downloadURL": "https://ghrc.nsstc.nasa.gov/pub/fieldCampaigns/gpmValidation/gcpex/dc8_camera_nadir/browse/gcpex_nadir_cameraDC8_20120220_160619.png", "format": "PNG", "mediaType": "image/png", "title": "Get a related visualization"}, {"@type": "dcat:Distribution", "description": "GCPEx Field Campaign Collection DOI", "downloadURL": "http://dx.doi.org/10.5067/GPMGV/GCPEX/DATA101", "format": "HTML", "mediaType": "text/html", "title": "View information related to this dataset"}, {"@type": "dcat:Distribution", "description": "The guide document contains detailed information about the dataset", "downloadURL": "http://ghrc.nsstc.nasa.gov/uso/ds_docs/gpmgv/gcpex/gpmncamdc8gcpex/gpmncamdc8gcpex_dataset.html", "format": "HTML", "mediaType": "text/html", "title": "View documentation related to this dataset"}, {"@type": "dcat:Distribution", "description": "AXIS 223M Network Camera specifications", "downloadURL": "https://ghrc.nsstc.nasa.gov/pub/fieldCampaigns/gpmValidation/gcpex/dc8_camera_nadir/doc/AXIS_ds_223m_32713_en_0809_lo.pdf", "format": "PDF", "mediaType": "application/pdf", "title": "View the primary investigator's documentation for this dataset"}, {"@type": "dcat:Distribution", "description": "PROGRAM - Read nadircam", "downloadURL": "https://ghrc.nsstc.nasa.gov/pub/fieldCampaigns/gpmValidation/gcpex/dc8_camera_nadir/doc/read_nadircam.pro", "format": "HTML", "mediaType": "text/html", "title": "Downloadable software applications"}, {"@type": "dcat:Distribution", "description": "The home page for the project or program which sponsored the dataset", "downloadURL": "https://ghrc.nsstc.nasa.gov/home/field-campaigns/GCPEx", "format": "HTML", "mediaType": "text/html", "title": "The dataset's project home page"}, {"@type": "dcat:Distribution", "description": "N/A", "downloadURL": "https://ghrc.nsstc.nasa.gov/pub/fieldCampaigns/gpmValidation/gcpex/dc8_camera_nadir/browse/", "format": "HTML", "mediaType": "text/html", "title": "Get a related visualization"}, {"@type": "dcat:Distribution", "description": "Instructions for citing GHRC data", "downloadURL": "https://ghrc.nsstc.nasa.gov/home/about-ghrc/citing-ghrc-daac-data", "format": "HTML", "mediaType": "text/html", "title": "View documentation related to this dataset"}], "identifier": "C1979637994-GHRC_DAAC", "issued": "2013-04-09", "keyword": ["earth-science", "land-surface", "platform-characteristics", "spectral-engineering", "surface-thermal-properties", "visible-wavelengths"], "landingPage": "https://doi.org/10.5067/GPMGV/GCPEX/CAMERA/DATA102", "language": ["en-US"], "modified": "2025-04-01", "programCode": ["026:001"], "publisher": {"@type": "org:Organization", "name": "NASA/MSFC/GHRC"}, "spatial": "-80.4001 43.4044 -67.495 47.0861", "temporal": "2012-02-20T14:06:19Z/2012-02-20T17:51:18Z", "theme": ["GCPEx", "geospatial"], "title": "GPM GROUND VALIDATION DC-8 CAMERA NADIR GCPEX V1"}
