AVIRIS Next Generation


The main objective of the AVIRIS-NG is to support NASA science and applications by measuring spectra as images that record the interaction of light with matter. These spectra are used to identify, measure, and monitor constituents of the Earth's surface and atmosphere.

Example science and application areas include:

  1. Ecology: composition, function, chlorophyll, leaf water, lignin, cellulose, pigments, structure, nonphotosynthetic constituents.
  2. Geology and soils: mineralogy, soil type.
  3. Coastal and Inland waters: chlorophyll, plankton, dissolved organics, sediments, benthic composition, aquatic vegetation, bathymetry.
  4. Snow and Ice Hydrology: snow cover fraction, graisize, dust, impurities, melting.
  5. Biomass Burning: subpixel temperatures and extent, smoke, combustion products.
  6. Atmosphere: water vapor, clouds properties, aerosols, absorbing gases.
  7. Environmental hazards: contaminants directly and indirectly, geological substrate.
  8. Calibration: aircraft and satellite sensors, sensor simulation, standard validation.
  9. Agriculture: crop type, crop health, nitrogen, leaf water, soil composition, soil salinity, soil carbon.
  10. Modeling: radiative transfer model validation and constraint.
  11. Algorithms: autonomous atmospheric correction, advance spectra derivation.
  12. Human infrastructure
