This imagery was collected as part of the Surface Biology and Geology High-Frequency Time Series (SHIFT) campaign which occurred during February to May, 2022, with a follow up activity for one week in September. The SHIFT campaign leveraged NASA's AVIRIS-NG facility instrument to collect VSWIR data at approximately a weekly cadence across a broad study area, enabling traceability analyses related to the science value of VSWIR revisits. This campaign will generate precise, high-frequency data on plant communities collected over nearly 1,656 square kilometers across Santa Barbara County, California, US, and nearby coastal Pacific waters. AVIRIS-NG is a pushbroom spectral mapping system with high signal-to-noise ratio (SNR), designed and toleranced for high performance spectroscopy. AVIRIS-NG measures reflected radiance at 5-nm intervals in the Visible to Shortwave Infrared (VSWIR) spectral range from 380-2510 nm. The AVIRIS-NG sensor has a 1 milliradian instantaneous field of view, providing altitude dependent ground sampling distances from 20 m to sub-meter range. The AVIRIS-NG L2A data are provided in ENVI binary format, which includes a flat binary file accompanied by a header (.hdr) file holding metadata in text format.", "distribution": [{"@type": "dcat:Distribution", "downloadURL": "https://search.earthdata.nasa.gov/search?q=SHIFT_AVIRISNG_L2A_refl_2376&ac=true", "format": "BIN", "mediaType": "application/octet-stream"}, {"@type": "dcat:Distribution", "downloadURL": "https://doi.org/10.3334/ORNLDAAC/2376", "format": "HTML", "mediaType": "text/html"}, {"@type": "dcat:Distribution", "downloadURL": "https://daac.ornl.gov/SHIFT/guides/SHIFT_AVIRISNG_L2A_refl_Fig1.jpg", "format": "JPEG", "mediaType": "image/jpeg"}, {"@type": "dcat:Distribution", "downloadURL": "https://data.ornldaac.earthdata.nasa.gov/public/shift/SHIFT_AVIRISNG_L2A_refl/comp/SHIFT_AVIRISNG_L2A_refl.pdf", "format": "PDF", "mediaType": "application/pdf"}, {"@type": "dcat:Distribution", "conformsTo": "http://www.isotc211.org/2005/gmi", "description": "The metadata's original source.", "downloadURL": "https://cmr.earthdata.nasa.gov/search/concepts/C3255170754-ORNL_CLOUD.iso19115", "format": "ISO", "mediaType": "text/xml", "title": "Original Metadata"}], "identifier": "10.3334/ORNLDAAC/2376", "keyword": ["earth-science-infrared-wavelengths-spectral-engineering-reflected-infrared", "earth-science-surface-radiative-properties-land-surface-reflectance"], "license": "https://www.usa.gov/government-works", "modified": "2026-04-06", "programCode": ["026:000"], "publisher": {"@type": "org:Organization", "name": "ORNL_DAAC"}, "spatial": "[[{\"WestBoundingCoordinate\":-120.643,\"NorthBoundingCoordinate\":34.8994,\"EastBoundingCoordinate\":-117.847,\"SouthBoundingCoordinate\":33.8561}],\"CARTESIAN\"]", "temporal": "2022-02-24/2022-05-29", "theme": ["Earth Science"], "title": "SHIFT: AVIRIS-NG L2A Unrectified Surface Reflectance Version 1"}
