Next-Generation Airborne Visible/Infrared Imaging Spectrometer

The NASA Airborne Visible/Infrared Imaging Spectrometer (AVIRIS) has been in operation since 1989 acquiring contiguous spectral measurements between 380 and 2510 nm for use by a range of terrestrial ecology science investigations related to: (1) pattern and spatial distribution of ecosystems and their components, (2) ecosystem function, physiology and seasonal activity, (3) biogeochemical cycles, (3) changes in disturbance activity, and (4) ecosystems and human health. While AVIRIS continue to make unique and significant science contributions, such as its deployment to the Gulf of Louisiana in May 2010 for the assessment of the amount of oil spilled by the offshore well, the need for a new sensor to share AVIRIS’ workload and to eventually replace AVIRIS is inevitable. Indeed, since the late summer of 2009 a new NASA Earth Science airborne sensor called the Next Generation Airborne Visible/Infrared Imaging Spectrometer (AVIRISng) is being developed by JPL through the funding support from the American Recovery and Reinvestment Act (ARRA). The technical and programmatic oversights of the AVIRISng development is provided by NASA’s Earth Science Technology Office (ESTO).

Similar to its predecessor, the AVIRIS-NG is being designed to be compatible with a broad array of possible aircraft platforms, such as NASA’s ER-2 jet, the Twin Otter turboprop, B200 King Air, and NASA’s Gulfstream III and V.
