  1. Integrated Activity 3(IA3) meeting regional to local modelling Carlos Borrego, Ana Isabel Miranda, Helena Martins, Joana Ferreira, Alexandra Monteiro, Liliana Salmin, Ana Margarida Costa and Anabela Carvalho University of Aveiro (UAVR/GEMAC) Portugal 21-23 June 2004, Paris

  2. Aveiro region University of Aveiro - PORTUGAL University of Aveiro Europe Portugal

  3. UAVR (GEMAC)what we do... Validation of localscale models Physical Simulation LOCAL SCALE 102 m - 104 m LOCAL SCALE MODELS AIR QUALITY AND METEOROLOGICAL DATA MESOSCALE MODELS MESOSCALE 104 m – 106 m Mesoscale Models Validation Meteorological Campaigns GLOBAL SCALE GEMAC in the internet: http://www.dao.ua.pt/gemac/default.htm

  4. UAVR in ACCENT • air quality modelling validation long-term simulation forecast • applied models CHIMERE CAMx VADIS
