These data were gathered during the Investigation of Microphysics and Precipitation for Atlantic Coast-Threatening Snowstorms (IMPACTS) field campaign. IMPACTS was a three-year sequence of winter season deployments conducted to study snowstorms over the U.S Atlantic Coast (2020-2022). The campaign aimed to (1) Provide observations critical to understanding the mechanisms of snowband formation, organization, and evolution; (2) Examine how the microphysical characteristics and likely growth mechanisms of snow particles vary across snowbands; and (3) Improve snowfall remote sensing interpretation and modeling to significantly advance prediction capabilities. The EXRAD IMPACTS dataset files are available from January 25 through February 27, 2020 in HDF-5 format.", "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%2FIMPACTS%2FEXRAD%2FDATA101", "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=exradimpacts", "format": "HTML", "mediaType": "text/html", "title": "Download this dataset"}, {"@type": "dcat:Distribution", "description": "IMPACTS Field Campaign Collection DOI", "downloadURL": "http://dx.doi.org/10.5067/IMPACTS/DATA101", "format": "HTML", "mediaType": "text/html", "title": "View information related to this dataset"}, {"@type": "dcat:Distribution", "description": "EXRAD Description and Sample Measurements from the Nadir Beam", "downloadURL": "http://har.gsfc.nasa.gov/index.php?section=14", "format": "HTML", "mediaType": "text/html", "title": "View information related to this dataset"}, {"@type": "dcat:Distribution", "description": "First Flights of ER-2 X-band Radar - EXRAD", "downloadURL": "http://science.gsfc.nasa.gov/sci/content/uploadFiles/scihi_atmos_ppt/2013_4_highlights.pdf", "format": "PDF", "mediaType": "application/pdf", "title": "View information related to this dataset"}, {"@type": "dcat:Distribution", "description": "The guide document contains detailed information about the dataset", "downloadURL": "https://ghrc.nsstc.nasa.gov/pub/fieldCampaigns/impacts/EXRAD/doc/exradimpacts_dataset.pdf", "format": "PDF", "mediaType": "application/pdf", "title": "View documentation related to this dataset"}, {"@type": "dcat:Distribution", "description": "Correction of Sampling Errors in Ocean Surface Cross-Sectional Estimates from Nadir-Looking Weather Radar, Notes and Correspondence", "downloadURL": "https://doi.org/10.1175/1520-0426(1997)014%3C0203:COSEIO%3E2.0.CO;2", "format": "HTML", "mediaType": "text/html", "title": "View this dataset's publications"}, {"@type": "dcat:Distribution", "description": "The EDOP Radar System on the High-Altitude NASA ER-2 Aircraft", "downloadURL": "https://doi.org/10.1175/1520-0426(1996)013%3C0795:TERSOT%3E2.0.CO;2", "format": "HTML", "mediaType": "text/html", "title": "View this dataset's publications"}, {"@type": "dcat:Distribution", "description": "TRMM Precipitation Radar Reflectivity Profiles as Compared with High-Resolution Airborne and Ground-Based Radar Measurements", "downloadURL": "https://doi.org/10.1175/1520-0450(2001)040%3C2080:TPRRPA%3E2.0.CO;2", "format": "HTML", "mediaType": "text/html", "title": "View this dataset's publications"}, {"@type": "dcat:Distribution", "description": "Chasing Snowstorms: The Investigation of Microphysics and Precipitation for Atlantic Coast-Threatening Snowstorms (IMPACTS) Campaign", "downloadURL": "https://doi.org/10.1175/BAMS-D-20-0246.1", "format": "HTML", "mediaType": "text/html", "title": "View this dataset's publications"}, {"@type": "dcat:Distribution", "description": "Investigation of Microphysics and Precipitation for Atlantic Coast Threatening Snowstorms (Impacts): The 2022 Deployment", "downloadURL": "https://doi.org/10.1109/IGARSS46834.2022.9883693", "format": "HTML", "mediaType": "text/html", "title": "View this dataset's publications"}, {"@type": "dcat:Distribution", "description": "IMPACTS Field Campaign Project Home Page", "downloadURL": "https://ghrc.nsstc.nasa.gov/home/field-campaigns/impacts", "format": "HTML", "mediaType": "text/html", "title": "The dataset's project home page"}, {"@type": "dcat:Distribution", "description": "IMPACTS Field Campaign Micro Article", "downloadURL": "https://ghrc.nsstc.nasa.gov/home/micro-articles/investigation-microphysics-and-precipitation-atlantic-coast-threatening-snowstorms", "format": "HTML", "mediaType": "text/html", "title": "View a micro article on this dataset"}, {"@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": "C1997744595-GHRC_DAAC", "issued": "2022-03-23", "keyword": ["atmosphere", "clouds", "earth-science"], "landingPage": "https://doi.org/10.5067/IMPACTS/EXRAD/DATA101", "language": ["en-US"], "modified": "2025-03-31", "programCode": ["026:001"], "publisher": {"@type": "org:Organization", "name": "NASA/MSFC/GHRC"}, "spatial": "-90.774 32.392 -71.691 44.76", "temporal": "2020-01-25T18:19:57Z/2020-02-27T14:50:09Z", "theme": ["IMPACTS", "geospatial"], "title": "ER-2 X-Band Doppler Radar (EXRAD) IMPACTS V1"}
