It is derived from Level 2, the Moderate Resolution Imaging Spectroradiometer (MODIS) Deep Blue aerosol products Collection 6.1 from Terra (MOD04_L2). The dataset covers the monthly mean from 2000 to 2022.\n\nThe FDS is calculated as the number of days per month when the daily dust optical depth is greater than a threshold optical depth (e.g., 0.025) with two quality flags: the lowest (1) and highest (3). It is advised to use flag 1, which is of lower quality, over dust source regions, and flag 3 over remote areas or polluted regions. Eight thresholds (0.025, 0.05, 0.1, 0.25, 0.5, 0.75, 1, 2) are saved separately in eight files.\n\nIf you have any questions, please read the README document first and post your question to the NASA Earthdata Forum (forum.earthdata.nasa.gov) or email the GES DISC Help Desk (gsfc-dl-help-disc@mail.nasa.gov).", "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/C3372183277-GES_DISC.iso19115", "format": "ISO", "mediaType": "text/xml", "title": "Original Metadata"}, {"@type": "dcat:Distribution", "downloadURL": "https://acdisc.gesdisc.eosdis.nasa.gov/data/DustStorm/MODFDS_MON_GLB_L3.1/", "format": "BIN", "mediaType": "application/octet-stream"}, {"@type": "dcat:Distribution", "downloadURL": "https://acdisc.gesdisc.eosdis.nasa.gov/data/DustStorm/MODFDS_MON_GLB_L3.1/doc/README_MODIS_FDS_Ginoux_v1_20250326.pdf", "format": "PDF", "mediaType": "application/pdf"}, {"@type": "dcat:Distribution", "downloadURL": "https://cmr.earthdata.nasa.gov/virtual-directory/collections/C3372183277-GES_DISC/temporal", "format": "BIN", "mediaType": "application/octet-stream"}, {"@type": "dcat:Distribution", "downloadURL": "https://disc.gsfc.nasa.gov/datacollection/MODFDS_MON_GLB_L3_1.html", "format": "HTML", "mediaType": "text/html"}, {"@type": "dcat:Distribution", "downloadURL": "https://disc.gsfc.nasa.gov/information/howto", "format": "BIN", "mediaType": "application/octet-stream"}, {"@type": "dcat:Distribution", "downloadURL": "https://docserver.gesdisc.eosdis.nasa.gov/public/project/Images/MODFDS_MON_GLB_L3.1.jpg", "format": "JPEG", "mediaType": "image/jpeg"}, {"@type": "dcat:Distribution", "downloadURL": "https://search.earthdata.nasa.gov/search/granules?p=C3372183277-GES_DISC", "format": "BIN", "mediaType": "application/octet-stream"}], "identifier": "10.5067/97NBV5RAIPB2", "keyword": ["earth-science-aerosols-atmosphere-aerosol-optical-depth-thickness", "earth-science-aerosols-atmosphere-dust-ash-smoke"], "license": "https://www.usa.gov/government-works", "modified": "2026-06-22", "programCode": ["026:000"], "publisher": {"@type": "org:Organization", "name": "NASA/GSFC/SED/ESD/TISL/GESDISC"}, "spatial": "[\"CARTESIAN\", [{\"WestBoundingCoordinate\": -175, \"NorthBoundingCoordinate\": 79.9, \"EastBoundingCoordinate\": 174.9, \"SouthBoundingCoordinate\": -80}]]", "temporal": "2000-01-01/2022-12-31", "theme": ["Earth Science"], "title": "Monthly Frequency of Dust Storm over Land for Varying Intensities, Based on MODIS Terra Deep Blue Level 2 Aerosol Products MOD04_L2 Collection 6.1, on a Global 0.1 by 0.1 Degree Grid, Level 3 Version 1 (MODFDS_MON_GLB_L3) at GES DISC"}
