Contiguous spectral measurements in the image domain made by the NASA Airborne Visible/Infrared Imaging Spectrometer (AVIRIS) have been used to advance a range of Terrestrial Ecology science investigation over the past two decades. Currently there are hundreds of relevant refereed journal articles. The calibrated, high signal-to-noise ratio measurements of AVIRIS are used to investigate terrestrial ecology topics 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.

We describe the current status of the AVIRIS instrument and science measurement capability in 2010 to support terrestrial ecology investigations. Selected terrestrial ecology science examples that use AVIRIS measurements are presented as well.

NASA has recently begun development of the Next Generation Airborne Visible/Infrared Imaging Spectrometer (AVIRISng). AVIRISng will exceed the spectral, radiometric and spatial measurement capabilities of AVIRIS-classic and support existing and new terrestrial ecology science. We present the science measurement characteristics of AVIRISng and development status.
