ORNL DAAC Data Release - Airborne Visible/InfraRed Imaging Spectrometer - 5th Generation (AVIRIS-5)

[ORNL - mtdonova]

The Oak Ridge National Laboratory Distributed Active Archive Center (ORNL DAAC) released new datasets for the Airborne Visible/InfraRed Imaging Spectrometer - 5th Generation (AVIRIS-5) facility instrument collection. These datasets include files that support the Western Diversity Time Series (WDTS) field investigation, the Tokyo Field Campaign (Tokyo-FC), and the Geological Earth Mapping Experiment (GEMx).

The Airborne Visible/InfraRed Imaging Spectrometer - 5th Generation (AVIRIS-5) is an imaging spectrometer developed at NASA's Jet Propulsion Laboratory (JPL) and built for flight on NASA airborne platforms. It is the latest version of NASA AVIRIS spectrometers, following AVIRIS-C, AVIRIS-NG, and AVIRIS-3. AVIRIS-5 has 0.5 to 13 meter ground-sampling spatial resolution and is compatible with the ER-2, B-200, Gulfstream, and other airborne platforms. The spectrometer is identical in design to the Earth Surface Mineral Dust Source Investigation (EMIT) spectrometer that flies on the International Space Station (ISS).

AVIRIS-5 L1B Calibrated Radiance, Facility Instrument Collection
This dataset contains Level 1B (L1B) calibrated radiance images as well as observational geometry and illumination parameters from the Airborne Visible / Infrared Imaging Spectrometer-5 (AVIRIS-5) instrument. For each flight line, two file types are included: calibrated radiance (RDN) and orthocorrected observation geometry and illumination (ORT) in netCDF format. Both file types include a geolocation lookup table (GLT) for georeferencing pixels in UTM and geographic coordinates.

AVIRIS-5 L2A Orthocorrected Surface Reflectance, Facility Instrument Collection
This dataset contains Level 2A (L2A) surface reflectance images from the Airborne Visible / Infrared Imaging Spectrometer-5 (AVIRIS-5) instrument. Surface hemispherical directional reflectance was derived from calibrated radiance using an optimal estimation algorithm. For each flight line, two file types are included: orthocorrected surface reflectance (RFL_ORT) and orthocorrected reflectance uncertainty (UNC_ORT) in NetCDF format.

AVIRIS-5 L2B Greenhouse Gas Enhancements, Facility Instrument Collection
This dataset contains Level 2B (L2B) enhancements of greenhouse gases (GHG) derived from imagery collected by the Airborne Visible / Infrared Imaging Spectrometer-5 (AVIRIS-5) instrument. Products include methane and carbon dioxide enhancements, each with per-pixel uncertainties and sensitivities to the background. Concentrations are estimated from radiance measurements enhanced using a column-wise adaptive matched filter approach, which searches each pixel's radiance spectrum for deviations that are characteristic of a GHG's absorption spectrum. GHG data are provided in cloud optimized GeoTIFF (COG) format.

All three collections include quicklook images and text files in YAML format that document processing algorithms and parameters used during production.
