Ultrathin Tropical Tropopause Clouds (UTTCs) : I. Cloud morphology and occurrence [PDF]

, 2003
Subvisible cirrus clouds (SVCs) may contribute to dehydration close to the tropical tropopause. The higher and colder SVCs and the larger their ice crystals, the more likely they represent the last efficient point of contact of the gas phase with the ice

NICP: Dense normal based point cloud registration [PDF]

, 2015
In this paper we present a novel on-line method to recursively align point clouds. By considering each point together with the local features of the surface (normal and curvature), our method takes advantage of the 3D structure around the points for the ...
