                      for turning the scientist's dreams into viable flight
                      missions. The remote support from the meteorological
                      forecasters Peter van Velthoven and Rinus Scheele at KNMI
                      was much appreciated. We would further like to thank the
                      logistic team (Stefano Balestri and Heinz Finkenzeller) for
                      organizing and accompanying a successful and memorable
                      campaign, the Darwin RAAF base and Charles Darwin University
                      for their hospitality and logistic support, and the
                      forecasters at the BoM regional forecast center for great
                      assistance. ECMWF (in particular Adrian Simmons) is
                      acknowledged for generating tailored products and for
                      providing access to forecast data used extensively during
                      the campaign. We are grateful to Matt Wheeler (BoM) for
                      providing an analysis of equatorial wave activity during the
                      campaign. This work has been supported by the European

      abstract     = {An aircraft measurement campaign involving the Russian
                      high-altitude aircraft M55 Geophysica and the German DLR
                      Falcon was conducted in Darwin, Australia in November and
                      December 2005 as part of the European integrated project
                      SCOUT-O3. The overall objectives of the campaign were to
                      study the transport of trace gases through the tropical
                      tropopause layer (TTL), mechanisms of dehydration close to
                      the tropopause, and the role of deep convection in these
                      processes. In this paper a detailed roadmap of the campaign
                      is presented, including rationales for each flight, and an
                      analysis of the local and large-scale meteorological context
                      in which they were embedded. The campaign took place during
                      the pre-monsoon season which is characterized by a
                      pronounced diurnal evolution of deep convection including a
                      mesoscale system over the Tiwi Islands north of Darwin known
                      as "Hector". This allowed studying in detail the role of
                      deep convection in structuring the tropical tropopause
                      region, in situ sampling convective overshoots above storm
                      anvils, and probing the structure of anvils and cirrus
                      clouds by Lidar and a suite of in situ instruments onboard
                      the two aircraft. The large-scale flow during the first half
                      of the campaign was such that local flights, away from
                      convection, sampled air masses downstream of the "cold trap"
                      region over Indonesia. Abundant cirrus clouds enabled the
                      study of active dehydration, in particular during two TTL
                      survey flights. The campaign period also encompassed a
                      Rossby wave breaking event transporting stratospheric air to
                      the tropical middle troposphere and an equatorial Kelvin
                      wave modulating tropopause temperatures and hence the
                      conditions for dehydration.},
