Three-dimensional atmospheric data are provided at three-hour intervals for 35 sigma levels extending from the surface to 50 hPa.\n\nAlso known as the Model for Atmospheric Transport and Chemistry in Asia (MATCHA), the data comprise a wide range of variables intended to help assess the impacts of aerosols on the cryosphere in the HMA region, including: concentrations of black/brown carbon and other light absorbing particles (LAPs), broken out by source region; longwave/shortwave heating rates due to LAPs; wet/dry deposition of LAPs; precipitation and hydrological data; and meteorological state variables.\n\nThe simulation was generated using a fully coupled, regional chemistry-climate model (WRF-Chem-CLM-SNICAR), constrained by aerosol optical depth (AOD) and carbon monoxide (CO) satellite observations acquired by the Moderate Resolution Imaging Spectroradiometer (MODIS) and Measurements Of Pollution In The Troposphere (MOPITT) instruments, respectively.", "distribution": [{"@type": "dcat:Distribution", "description": "Direct download via HTTPS protocol.", "downloadURL": "https://n5eil01u.ecs.nsidc.org/HMA/HMA2_MATCHA.001/", "format": "HTML", "mediaType": "text/html", "title": "Download this dataset"}, {"@type": "dcat:Distribution", "description": "Includes a user's guide, supplemental documents like ATBDs and academic papers, How Tos, FAQs, etc.", "downloadURL": "https://doi.org/10.5067/CG4OT8DJX2Z7", "format": "HTML", "mediaType": "text/html", "title": "View documentation related to this dataset"}, {"@type": "dcat:Distribution", "description": "NASA's newest search and order tool for subsetting, reprojecting, and reformatting data.", "downloadURL": "https://search.earthdata.nasa.gov/search?q=HMA2_MATCHA+V001", "format": "HTML", "mediaType": "text/html", "title": "Download this dataset through Earthdata Search"}, {"@type": "dcat:Distribution", "description": "Provides access to data, documentation, tools, citation information, support, and other resources.", "downloadURL": "https://doi.org/10.5067/CG4OT8DJX2Z7", "format": "HTML", "mediaType": "text/html", "title": "This dataset's landing page"}, {"@type": "dcat:Distribution", "description": "Search and filter data files using a map-based interface", "downloadURL": "https://nsidc.org/data/data-access-tool/HMA2_MATCHA/versions/1/", "format": "HTML", "mediaType": "text/html", "title": "Download this dataset"}, {"@type": "dcat:Distribution", "description": "Search results for publications that cite this dataset by its DOI.", "downloadURL": "https://scholar.google.com/scholar?q=10.5067%2FCG4OT8DJX2Z7", "format": "HTML", "mediaType": "text/html", "title": "Google Scholar search results"}], "identifier": "C3084467669-NSIDC_ECS", "issued": "2003-01-01", "keyword": ["aerosols", "atmosphere", "atmospheric-radiation", "earth-science", "national-geospatial-data-asset", "ngda"], "landingPage": "https://doi.org/10.5067/CG4OT8DJX2Z7", "language": ["en-US"], "modified": "2025-03-31", "programCode": ["026:001"], "publisher": {"@type": "org:Organization", "name": "NASA NSIDC DAAC"}, "spatial": "44.647 4.873 138.953 57.767", "temporal": "2003-01-01T00:00:00Z/2019-08-31T23:59:59.999Z", "theme": ["geospatial"], "title": "High Mountain Asia 12 km Modeled Estimates of Aerosol Transport, Chemistry, and Deposition Reanalysis, 2003-2019 V001"}
