Organizers of Session C23, "Snow and Ice Surface Roughness and Remote
Sensing," announce a call for abstracts. The session will be convened at
the American Geophysical Union (AGU) Fall Meeting, 14-18 December 2009,
in San Francisco, California.

Snow and ice surface roughness plays an important role in many
cryospheric and atmospheric processes, and many environmental and
geophysical processes manifest themselves through changes in surface
roughness. For example, surface roughness influences energy flux between
terrestrial or marine ice surfaces and the lower atmosphere, wind
creates sastrugi, crevasse fields open as ice velocity changes, and sea
ice exhibits surface forms indicative of its formation and kinematics.

Contributions are invited from any area of snow and land/sea ice
research, including observational or analytical topics, statistical
analysis, phenomena at every scale, and field, aerial, and satellite
observations. A focus of the session is the relationship of surface
roughness and remote sensing observations, including active and passive
microwave data, satellite imagery, and laser and radar altimetry:
- How does snow and ice surface roughness influence the remote
sensing signal?
- What can we learn about cryospheric processes from surface
roughness and its spatial variability?

The abstract submission deadline for this and all other sessions is
Thursday, 3 September 2009, at 11:59 pm Eastern Daylight Time. To submit
an abstract, you must enter the first author's current AGU member ID and
password at: http://agu-fm09.abstractcentral.com/.
