      abstract     = {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 phase and, hence, the last
                      dehydrating step, before the air enters the stratosphere.
                      The first simultaneous in situ and remote sensing
                      measurements of SVCs were taken during the APE-THESEO
                      campaign in the western Indian ocean in February/March 1999.
                      The observed clouds, termed Ultrathin Tropical Tropopause
                      Clouds (UTTCs), belong to the geometrically and optically
                      thinnest large-scale clouds in the Earth's atmosphere.
                      Individual UTTCs may exist for many hours as an only 200-300
                      m thick cloud layer just a few hundred meters below the
                      tropical cold point tropopause, covering up to 10(5) km(2).
                      With temperatures as low as 181 K these clouds are prime
                      representatives for defining the water mixing ratio of air
                      entering the lower stratosphere.},
