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. This is the NASA Earth Observing System Data and Information System (EOSDIS) facility instrument archive of these data. The NASA AVIRIS-5 is a spectral mapping system that measures reflected radiance at 5-nm intervals in the Visible to Shortwave Infrared (VSWIR) spectral range from 380-2500 nm. The AVIRIS-5 sensor has a 40-degree instantaneous field of view with 1239 pixels, providing altitude-dependent ground sampling distances from 12 m to sub-meter range. This spectrometer measures radiance from surface and atmosphere and is extremely similar in design to the orbital Earth Surface Mineral Dust Source Investigation (EMIT) spectrometer. 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. In addition, ancillary files for each flight line are provided, including a quick look image in TIFF format and text files in YAML format that document processing algorithms and parameters used during production. AVIRIS-5 supports NASA Science and applications in many areas including plant composition and function, geology and soils, wetlands and aquatic ecosystems, greenhouse gas mapping, and calibration of orbital platforms.
