The authors present measurements of boundary layer properties during the first Lagrangian observation period of the Atlantic Stratocumulus Transition Experiment (ASTEX), June 1992. In this experiment a column of air was tracked for 48 hours as it moved south-westward over water with increasing sea surface temperatures. The authors use the NCAR Electra and MRF C-130 aircraft data to study the cloud evolution during this Lagrangian. From the aircraft data the authors analyzed the turbulence, radiation and micro-physical processes in this cloud-topped atmospheric boundary layer. The authors use initialized analysis fields of the ECMWF to obtain the large scale flow structure: flow fields, temperature, subsidence, etc.
