Data were collected as part of the Delta-X Spring and Fall 2021 deployments that occurred from 2021-03-27 to 2021-04-06 and from 2021-08-18 to 2021-08-25. Additionally, L2 data from flights flown specifically to capture the Significant Event of Hurricane Ida are provided.  This includes 56 files from flights conducted following Hurricane Ida from 2021-09-23 to 2021-09-25. Hurricane Ida made landfall over this region on 2021-08-29. AVIRIS-NG is a pushbroom spectral mapping system with a high signal-to-noise ratio (SNR) designed for high performance imaging spectroscopy. AVIRIS-NG measures the wavelength range from 380 nm to 2510 nm with 5-nm sampling resolution. For this dataset, spatial resolution varies from 3.8-5.4 meters. For this campaign, the AVIRIS-NG instrument was deployed on the Dynamic Aviation King Air B200 platform. This dataset represents one part of a multisensor airborne sampling campaign conducted by different aircraft teams for the Delta-X Campaign. Data are provided in ENVI file 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/C2430019879-ORNL_CLOUD.iso19115", "format": "ISO", "mediaType": "text/xml", "title": "Original Metadata"}, {"@type": "dcat:Distribution", "downloadURL": "https://daac.ornl.gov/DELTAX/guides/DeltaX_L2_AVIRIS_Reflectance_Fig1.jpg", "format": "JPEG", "mediaType": "image/jpeg"}, {"@type": "dcat:Distribution", "downloadURL": "https://data.ornldaac.earthdata.nasa.gov/public/deltax/DeltaX_L2_AVIRIS_Reflectance/comp/DeltaX_L2_AVIRIS_Reflectance.pdf", "format": "PDF", "mediaType": "application/pdf"}, {"@type": "dcat:Distribution", "downloadURL": "https://data.ornldaac.earthdata.nasa.gov/public/deltax/DeltaX_L2_AVIRIS_Reflectance/comp/Hurricane_Ida_file_list.txt", "format": "TXT", "mediaType": "text/plain"}, {"@type": "dcat:Distribution", "downloadURL": "https://deltax.jpl.nasa.gov/", "format": "BIN", "mediaType": "application/octet-stream"}, {"@type": "dcat:Distribution", "downloadURL": "https://doi.org/10.3334/ORNLDAAC/1988", "format": "HTML", "mediaType": "text/html"}, {"@type": "dcat:Distribution", "downloadURL": "https://search.earthdata.nasa.gov/search/granules?p=C2430019879-ORNL_CLOUD", "format": "BIN", "mediaType": "application/octet-stream"}], "identifier": "10.3334/ORNLDAAC/1988", "keyword": ["earth-science-geomorphic-landforms-processes-land-surface-coastal-landforms", "earth-science-infrared-wavelengths-spectral-engineering-reflected-infrared", "earth-science-surface-radiative-properties-land-surface-reflectance", "earth-science-surface-water-terrestrial-hydrosphere-surface-water-features", "earth-science-visible-wavelengths-spectral-engineering-visible-imagery"], "license": "https://www.usa.gov/government-works", "modified": "2026-06-22", "programCode": ["026:000"], "publisher": {"@type": "org:Organization", "name": "ORNL_DAAC"}, "spatial": "[\"CARTESIAN\", [{\"WestBoundingCoordinate\": -91.6389, \"NorthBoundingCoordinate\": 29.85, \"EastBoundingCoordinate\": -89.5899, \"SouthBoundingCoordinate\": 29.0248}]]", "temporal": "2021-03-27/2021-09-25", "theme": ["Earth Science"], "title": "Delta-X: AVIRIS-NG L2 Surface Reflectance, MRD Louisiana, 2021"}
