The Multi-angle Imaging SpectroRadiometer (MISR) instrument is schedul
ed for launch aboard the first of the Earth Observing System (EOS) spa
cecraft, EOS-AM1. MISR will provide global, radiometrically calibrated
, georectified, and spatially coregistered imagery at nine discrete vi
ewing angles and four visible/near-infrared spectral bands. Algorithms
specifically developed to capitalize on this measurement strategy wil
l be used to retrieve geophysical products for studies of clouds, aero
sols, and surface radiation. This paper provides an overview of the as
-built instrument characteristics and the application of MISR to remot
e sensing of the earth.
