ABoVE: Hyperspectral Imagery from AVIRIS-NG, Alaskan and Canadian Arctic, 2017-2018
This dataset has been updated to include data collected during 2018 flights over the Arctic-Boreal Vulnerability Experiment (ABoVE) domain. The dataset provides Level 1 radiance and Level 2 surface reflectance measured by the Airborne Visible/Infrared Imaging Spectrometer-Next Generation (AVIRIS-NG) instrument. Spectra measured by AVIRIS-NG are used to identify, measure, and monitor constituents of the Earth's surface and atmosphere. Ecological applications include species composition, structure, and function; chlorophyll, leaf water, lignin, cellulose, pigment, and non-photosynthetic constituent content.
AVIRIS-NG data file sizes can be prohibitively large owing to the large number of raster bands. We created a new tutorial to show users how to work with this data in Python. The tutorial demonstrates how to extract AVIRIS-NG imagery at specific locations, plot individual bands, calculate NDVI and other vegetation indices, and save outputs.

We also offer a video tutorial showing how to find and download AVIRIS-NG data from the ABoVE campaign for your region of interest.

The Arctic-Boreal Vulnerability Experiment (ABoVE) is a NASA Terrestrial Ecology Program field campaign that links field-based, process-level studies with geospatial data products derived from airborne and satellite sensors.
