AVIRIS-NG is an acronym for the Airborne Visible InfraRed Imaging Spectrometer - Next Generation. AVIRIS-NG has been developed to provide continued access to high signal-to-noise ratio imaging spectroscopy measurements in the solar reflected spectral range. AVIRIS-NG is expected to replace the AVIRIS-Classic instrument that has been flying since 1986.
AVIRIS-NG measures the wavelength range from 380 nm to 2510 nm with 5 nm sampling. Spectra are measured as images with 600 cross-track elements and spatial sampling from 0.3 m to 4.0 m from a Twin Otter platform. In the future, a high altitude platform is expected to be available. AVIRIS-NG has better than 95% cross-track spectral uniformity and >= 95% spectral IFOV uniformity.
