GCPEx addressed shortcomings in the GPM snowfall retrieval algorithm by collecting microphysical properties, associated remote sensing observations, and coordinated model simulations of precipitating snow. The POSS is a bi-static X-band Doppler radar designed by Environment Canada. The POSS measures a signal whose frequency is proportional to the particle Doppler velocity and whose amplitude is proportional to the particle scattering cross-section. Its measurements can be used to provide information regarding precipitation occurrence, type, rate, and raindrop size distribution.", "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%2FPOSS%2FDATA201", "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=gpmpossgcpex", "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/poss_EC/browse/CARE/gcpex_poss_pr_20120229_EC_CARE-TNE.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/gpmpossgcpex/gpmpossgcpex_dataset.html", "format": "HTML", "mediaType": "text/html", "title": "View documentation related to this dataset"}, {"@type": "dcat:Distribution", "description": "Description of the POSS post processed \u00bf\u00bf\u00bfPR\u00bf\u00bf\u00bf file Updated Feb. 11 2013", "downloadURL": "https://ghrc.nsstc.nasa.gov/pub/fieldCampaigns/gpmValidation/gcpex/poss_EC/doc/POSS_Documentation_for_PR_files_130211.doc", "format": "DOC", "mediaType": "application/msword", "title": "View the primary investigator's documentation for this dataset"}, {"@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/poss_EC/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": "C1979685182-GHRC_DAAC", "issued": "2013-09-03", "keyword": ["atmosphere", "earth-science", "precipitation", "radar", "spectral-engineering"], "landingPage": "https://doi.org/10.5067/GPMGV/GCPEX/POSS/DATA201", "language": ["en-US"], "modified": "2025-03-31", "programCode": ["026:001"], "publisher": {"@type": "org:Organization", "name": "NASA/MSFC/GHRC"}, "spatial": "-79.93 44.18 -79.64 44.23", "temporal": "2012-01-15T00:00:00Z/2012-03-01T23:59:59Z", "theme": ["GCPEx", "geospatial"], "title": "GPM GROUND VALIDATION ENVIRONMENT CANADA (EC) PRECIPITATION OCCURRENCE SENSOR SYSTEM (POSS) GCPEX V1"}
