3D reconstruction of tropospheric cirrus clouds

In this paper, we present a series of results from stereo-imagery of cirrus clouds in the troposphere. These clouds are either of natural origin or are created by aircraft exhausts. They are presently considered to be a major cause for the climate change. Two observation campaigns were conducted in France in 2013 and 2014. The observing sites were located in Marnay (47 circle 17'31.5'' N, 5 degrees 44'58.8'' E; altitude 275 m) and in Mont Poupet (46 degrees 58'31.5'' N, 5 degrees 52'22.7'' E; altitude 600 m). The distance between both sites was 36 km. We used numeric CMOS photographic cameras. The image processing sequence included a contrast enhancement and a perspective inversion to obtain a satellite-type view. Finally, the triangulation procedure was used in an area that is a common part of both fields of view. (C) 2016 COSPAR. Published by Elsevier Ltd. All rights reserved.
