AVIRIS  

DÉFINITION

  • The Airborne Visible InfraRed Imaging Spectrometer (AVIRIS) is a unique optical sensor that delivers calibrated images of the upwelling spectral radiance in 224 contiguous spectral channels (also called bands) with wavelengths from 400 to 2500 nanometers (nm). The instrument flies aboard a NASA ER-2 airplane (a U2 plane modified for increased performance) at approximately 20 km above sea level, at about 730 km/hr. AVIRIS has flown all across the US, plus Canada and Europe. The science objectives of the AVIRIS project are broad. The main objective is to identify, measure, and monitor constituents of the Earth's surface and atmosphere based on molecular absorption and particle scattering signatures. Research with AVIRIS is dominantly directed towards understanding processes related to the global environment and climate change. AVIRIS research areas include: Ecology Oceanography Geology Snow hydrology Cloud and atmospheric studies For more information on current and past mission involving AVIRIS or access to AVIRIS data, See: https://aviris.jpl.nasa.gov/
