  1. Inverse Problems and Earth System ModelingChallenges and opportunities in the Americas…The French connection Laura Gallardo Jaime Ortega Axel Osses LGK Dic 2005

  2. Contents • Our group on Earth System Modeling and Inverse Problems • Challenges and opportunities in the Americas, e.g., SAEMC • The French connections and possibilities • Concrete examples and products • Summary LGK Dic 2005

  3. Chemical weather forecast…Kalman filter • Aerosol-cloud-climate interactions…IP and integral equations • Downscaling of climate change scenarios…Boundary conditions • Stratosphere-troposphere exchange…Discontinuities Earth System Modeling and Inverse Problems LGK Dic 2005

  4. Project$ • Urban Mobile Emissions in South American Cities (UMESAM, 2004-2005)…South American Emissions, Megacities, and Climate (SAEMC, 2006-2010) • A Europe-South America Network for Climate Change Assessment and Impact Studies (EU-CLARIS, 2004-2007) • CODELCO-IM2, 2004/2005:Design of an emission survey and control system • ECOS (3+2) • INRIA-CONICYT(1) • FONDECYT (3) LGK Dic 2005

  5. South American Megacities • SA M-cities concentrate population (75%), environmental problems and resources • M-cities are global change drivers • This issue can merge efforts and strenghten the region (Science-Policy) LGK Dic 2005

  6. South American Emissions, Megacities, and Climate (SAEMC, 2006-2010, 640 kUS$ ) • Emissions scenarios estimate and evaluation. • Dynamical down-scaling of climate change scenarios • Implementation of a pilot chemical weather forecast network • Prospective characterization of aerosols inside and downwind South American megacities LGK Dic 2005

  7. To take over the world! SAEMC –Participants and connections LGK Dic 2005

  8. IGAC SSC Meeting, October 2005 IGAC Task activity on South American M-cities from 2006? LGK Dic 2005

  9. CPTEC Chemical weather forecast • Brazil/CPTEC is the leading weather center in South America • We aim at establishing a regional network for operational chemical weather forecast • We start with a pilot activity linking CPTEC and the Chilean Weather Office (DMC) • DMC will be using POLYPHEMUS, a French model LGK Dic 2005

  10. Axel…examples LGK Dic 2005

  11. S ... • We have established at the CMM a multidisciplinary research group working on IP and ESM • Inverse modeling for source determination and data assimilation are active research areas • There are strong (South) American, and European connections, as expressed in several projects. • South American Emissions, Megacities, and Climate (SAEMC, 2006-2010) will provide a solid basis for research and international collaboration • CNRS and INRIA have played a key role for our work, and we expect to count on that support in the next future LGK Dic 2005
