The D3R was developed by a government-industry-academic consortium with funding from NASA's Global Precipitation Measurement (GPM) Project. It operates at the ku (13.91 GHz \u00b1 25 MHz) and ku (35.56 GHz \u00b1 25 MHz) frequencies covering a fixed range from 450 m to 39.75 km. The instrument's data are available in netCDF-4 format with browse imagery available in PNG format.", "distribution": [{"@type": "dcat:Distribution", "conformsTo": "http://www.isotc211.org/2005/gmi", "description": "The metadata's original source.", "downloadURL": "https://cmr.earthdata.nasa.gov/search/concepts/C1981506869-GHRC_DAAC.iso19115", "format": "ISO", "mediaType": "text/xml", "title": "Original Metadata"}, {"@type": "dcat:Distribution", "downloadURL": "http://dx.doi.org/10.5067/GPMGV/IPHEX/DATA101", "format": "HTML", "mediaType": "text/html"}, {"@type": "dcat:Distribution", "downloadURL": "http://pmm.nasa.gov/science/ground-validation/D3R", "format": "BIN", "mediaType": "application/octet-stream"}, {"@type": "dcat:Distribution", "downloadURL": "https://ghrc.earthdata.nasa.gov/browseui/#pub/gpmd3riphx__1/browse/", "format": "BIN", "mediaType": "application/octet-stream"}, {"@type": "dcat:Distribution", "downloadURL": "https://ghrc.earthdata.nasa.gov/browseui/#pub/gpmd3riphx__1/browse/2014-05-01/ka_clutterfilter_off/iphex_d3r_ka_20140501_184519_01_rhi_291az_zdb.png", "format": "PNG", "mediaType": "image/png"}, {"@type": "dcat:Distribution", "downloadURL": "https://ghrc.earthdata.nasa.gov/browseui/#pub/gpmd3riphx__1/docs/Chandra_D3R_igarss_2010.pdf", "format": "PDF", "mediaType": "application/pdf"}, {"@type": "dcat:Distribution", "downloadURL": "https://ghrc.earthdata.nasa.gov/browseui/#pub/gpmd3riphx__1/docs/Vega_D3R_igarss_2010.pdf", "format": "PDF", "mediaType": "application/pdf"}, {"@type": "dcat:Distribution", "downloadURL": "https://ghrc.earthdata.nasa.gov/browseui/#pub/gpmd3riphx__1/docs/gpmd3riphx_dataset.pdf", "format": "PDF", "mediaType": "application/pdf"}, {"@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", "downloadURL": "https://ghrc.nsstc.nasa.gov/home/field-campaigns/iphex", "format": "BIN", "mediaType": "application/octet-stream"}, {"@type": "dcat:Distribution", "downloadURL": "https://search.earthdata.nasa.gov/search/granules?p=C1981506869-GHRC_DAAC", "format": "BIN", "mediaType": "application/octet-stream"}], "identifier": "10.5067/GPMGV/IPHEX/D3R/DATA101", "keyword": ["earth-science-precipitation-atmosphere-liquid-precipitation", "earth-science-radar-spectral-engineering-doppler-velocity", "earth-science-radar-spectral-engineering-radar-reflectivity"], "license": "https://www.usa.gov/government-works", "modified": "2026-06-22", "programCode": ["026:000"], "publisher": {"@type": "org:Organization", "name": "NASA/MSFC/GHRC"}, "spatial": "[\"CARTESIAN\", [{\"WestBoundingCoordinate\": -81.9632, \"NorthBoundingCoordinate\": 35.1959, \"EastBoundingCoordinate\": -81.9631, \"SouthBoundingCoordinate\": 35.1959}]]", "temporal": "2014-05-01/2014-06-15", "theme": ["Earth Science"], "title": "GPM GROUND VALIDATION DUAL-FREQUENCY DUAL-POLARIZED DOPPLER RADAR (D3R) IPHEX"}
