The Airborne Visible/Infrared Imaging Spectrometer - 3rd Generation (AVIRIS-3) is the third of the AVIRIS spectrometer facility instrument series and has higher signal-to-noise ratio performance than AVIRIS-Classic (AVIRIS-C) or AVIRIS-Next Generation (AVIRIS-NG). The core spectrometer of AVIRIS-3 is an optically fast, F/1.8 Dyson imaging spectrometer spanning a wide width (39.5-degree field of view). 

AVIRIS-3 started operation in 2023 and provides measurements in 285 contiguous spectral channels with wavelengths in the solar reflected spectral range (390-2500 nm) with 7.4 nm sampling.
