Announcement March 2008 The GEWEX Cloud System Study (GCSS) investigates cloud systems, their role in the climate system and their representation in models with a view to improving our capability to predict weather and climate using state-of the-art modeling and data assimilation systems. GCSS will hold a meeting to review and discuss "Advances in Modeling and observing Clouds and Convection" from June 2-6 2008 at Meteo-France, Toulouse, France. Key areas to be discussed at this meeting during the plenary sessions in the mornings are: New observations and recent field campaigns Tropical Convection High Resolution Modeling on Large Domains Cloud Climate Feedbacks In the afternoons there will be parallel breakout sessions of various working groups on Boundary layer clouds - contact : adrian.lock@metoffice.gov.uk Cirrus clouds - contact : dobbie@env.leeds.ac.uk Extra-tropical clouds - contact : gtselioudis@giss.nasa.gov Deep convective clouds - contact : jon.petch@metoffice.gov.uk Polar clouds - contact : pinto@ucar.edu GEWEX Pacific cross-section intercomparison (GPCI) - contact : teixeira@jpl.nasa.gov Cloud and radiation metrics - contact : robert.pincus@noaa.gov Cloud climate feedback intercomparison project (CFMIP) - contact : Sandrine.Bony@lmd.jussieu.fr Cloud microphysics - contact : Ulrike.lohmann@env.ethz.ch
