Several mountain ranges and a portion of the Amur River are visible
in this set of MISR images of Russia's far east Khabarovsk region.
The images were acquired on May 13, 2001 during Terra orbit 7452.
The view from MISR's 70-degree forward-looking camera is at the top
left; the 26-degree forward-looking view is at the top right. The
larger image at the bottom is a stereo "anaglyph" created using
the cameras at two intermediate angles. To view the stereo image in
3-D you need red/blue glasses with the red filter placed over
your left eye. All of the images are oriented with north to the
left to facilitate stereo viewing. Each image covers an area about
345 kilometers x 278 kilometers.
The Amur River, in the upper right, and Lake Bolon, at the top
center, are most prominent in the 26-degree view due to sunglint
(mirror-like reflection of the Sun's rays by the water). The Amur
River valley is a primary breeding ground for storks and cranes and
a stopover for large numbers of migratory birds. About 20% of the
Amur wetlands are protected by official conservation measures, but
human development has converted large portions to agricultural
uses. Other notable features in these images are several mountain
chains, including the Badzhal'skiy to the left of center and the
Bureiskiy in the lower left.
Smoke plumes from several forest fires can be seen. They are
especially apparent in the 70-degree view where the smoke's
visibility is accentuated, in part, by the long slant path through
the atmosphere. The largest plumes are in the lower left and upper
right, with some smaller plumes above and to the right of the image
centers. In the upper images the hazy region in the vicinity of
these smaller plumes has the appearance of low-altitude smoke, but
depth perception provided by the stereo anaglyph shows that it is
actually a distinct layer of high-altitude cirrus clouds. Whether
the cirrus is related to the fires is uncertain. It is possible,
however, for the fires have to have heated the lower atmosphere
enough to create bubbles of hot air. As such bubbles rise, they can
force stable, nearly saturated air above to move even higher,
triggering the formation of ice clouds. Visualization of other
three-dimensional characteristics of the scene, such as the
intermediate-altitude layer of cumulus clouds along the left side,
is made possible by the stereo imagery.
