AVIRIS: Cal/Val<br />
<strong>Science</strong> Focus: Carbon Cycle & Ecosystems<br />
Sponsor: D. Wickland, <strong>NASA</strong> HQ<br />
Location: U.S. and Canada<br />
From June 5 through August 14,<br />
<strong>2008</strong>, a total of 20 AVIRIS science<br />
flights were flown on the ER-2,<br />
totaling 92.7 flight hours. It included<br />
a deployment to Westover ARB,<br />
MA, for the month of July. Other data sites<br />
included areas in central and southern<br />
California, Michigan, Wisconsin, Maryland and<br />
Minnesota. AVIRIS data was also collected<br />
over experiment sites in British Columbia,<br />
Alberta, Saskatchewan, Manitoba, Ontario,<br />
and Québec, Canada.<br />
The series of AVIRIS flights were initiated with<br />
an in-flight spectral, radiometric, spatial, and<br />
uniformity calibration and characterization of<br />
the AVIRIS imaging spectrometer. The science<br />
data gathered over experiment sites included<br />
characterization of forest functional types and<br />
their role in mediating ecosystem response<br />
to environmental change, carbon cycling,<br />
vegetation nitrogen status and surface albedo,<br />
field validation with seepage from marine,<br />
urban and submerged city sources, and live<br />
fuel moisture retrieval for Southern California<br />
fire danger assessments.<br />
<strong>Science</strong> data was successfully gathered over<br />
all requested experiment sites by the ER-<br />
2 team. AVIRIS scientists included Philip<br />
Dennison, Dar Roberts, Scott Ollinger, and<br />
Phil Townsend. The AVIRIS instrument<br />
is managed by JPL (Instrument Manager:<br />
Michael Eastwood, Chief Scientist: Robert<br />
Green).<br />
