AVIRIS is an acronym for the Airborne
Visible InfraRed Imaging
Spectrometer. AVIRIS is a world class instrument in the
realm of Earth Remote Sensing. It 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. In a
nutshell, 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
The role of the
Jet Propulsion Laboratory
in the AVIRIS project is threefold:
- Principal investigator
- Instrument in-house design,
fabrication, testing, and calibration
- Ground processing algorithms,
software development, and data distributions
