AB: We present a technique for stereoscopically retrieving altitudes of thin cirrus, smoke plumes, and stratospheric clouds viewed by the Multi-angle Imaging SpectroRadiometer (MISR) aboard the EOS-TERRA satellite. This technique differs from the operational MISR stereoscopic retrieval by using oblique perspective and revised algorithms to enhance coverage for features that may exhibit minimal texture at nadir due to homogeneous structure or limited optical depth. Stereoscopic retrievals from this technique are evaluated relative to collocated Geosynchronous Laser Altimeter System observations and operational MISR stereo product retrievals over the Antarctic during the time frame from September 29th to October 12th, 2003. Furthermore, results are applied to case studies of polar stratospheric cloud development, and lofting of smoke plumes into the stratosphere.
