How Does Ground Clutter Affect CloudSat Snowfall Retrievals Over Ice Sheets?
International audience CloudSat has provided the first spaceborne snowfall observations in polar regions. Nevertheless, CloudSat retrievals may be affected by ground clutter even if the snowfall rate at the surface is estimated from the reflectivity measured at about 1200 m above land/ice surface. I...
