ABoVE: Hyperspectral Imagery AVIRIS-NG, Alaska, Canada, and Iceland, 2017-2022, V3

Overview

Description

This dataset provides a replacement of previously published Level 2 surface reflectance ABoVE AVIRIS-NG files as well as previously unpublished L1 radiance and L2 reflectance for 2021 and 2022. AVIRIS-NG is the Airborne Visible/Infrared Imaging Spectrometer-Next Generation instrument. Measurements were conducted during flights over the Arctic-Boreal Vulnerability Experiment (ABoVE) domain during summer months from June to August in 2017, 2018, 2019, 2021, and 2022. In this Version 3, the L2 reflectance files for all years were processed (or reprocessed if previously published) with an updated and consistent reflectance algorithm. For years 2018 and 2019, Level 1 radiance data are unchanged from the V2 files and provided in this V3. Flights in 2021 occurred over Iceland. AVIRIS-NG measures reflected radiance in 425 bands at 5-nanometer (nm) intervals in the visible to shortwave infrared spectral range between 380 and 2510 nm. Measurements are radiometrically and geometrically calibrated and provided at approximately 5-meter spatial resolution. The data include flight lines covering areas of interest to the ABoVE campaign over much of Alaska and western Canada. These data will allow researchers to characterize ecosystem structure and function near the height of the growing season. This dataset represents one part of a multi-sensor airborne sampling campaign conducted by eleven different aircraft teams for ABoVE. The imagery data are provided in ENVI format along with a RGB composite image for each flight line and shapefiles showing imagery boundaries.
