Keeping the tradition of having specialists in air quality modeling, the Atmospheric Sciences Department from the São Paulo University will realize from 23 to 27 February 2015, a new workshop providing a close interaction between specialists, users and people interested in acquire skilless on WRF-Chem, CMAQ, SMOKE and SPRAY modeling. Following the Workshop, from 02 to 06 March 2015, the Department will offer a summer course related to "Atmospheric Modeling (physical and chemical theoretical development)".

The workshop will start with all participants in a common room. In the Monday morning will be given three lectures introducing CMAQ, SMOKE and SPRAY models. The common class will continue with WRF (Weather Research and Forecast), an important and widely used meteorological model, providing prognostics of the atmosphere state, and, also, interpolations of preexisting meteorological data. After this general class, the students will continue working with the modeling system they chose in the inscription.

One group will follow with WRF-Chem, the fully coupled ''online'' Weather Research and Forecasting/Chemistry model to simulate chemistry and aerosols from cloud to regional scales. WRF-Chem has been developed by NOAA with contributions from NCAR, PNNL, EPA, and university scientists.

Othe group will deal with U.S. EPA's Community Multi-scale Air Quality - CMAQ model and SMOKE (Sparse Matrix Operator Kernel Emissions). The first is a powerful open-source computational tool used by several institutions and research groups, for air quality management and study. The second primarily is an emissions processing system designed to create gridded, speciated, hourly emissions for input into CMAQ and a variety of other air quality models.

The third option will be SPRAY, a three-dimensional lagrangian particle dispersion model initially developed by the "Centro Ricerca Ambiente e Materiali da ENEL (Ente Nazionale per Energia Elettrica)" and by the "Istituto di Cosmo-Geofisica del Consiglio Nazionale di Richerca (Italy)", and still developed by the Arianet S.r.l.. This code reproduces the transport, dispersion, dry and wet deposition and radioactive decay of airborne chemically inert species released in meteorological complex conditions, often marked by spatial and temporal inhomogeneities of the meteo-diffusive variables.

Besides given an opportunity of discussing air quality models in general, this workshop was planned to provide an effective contact of the participants with recognized system of models, introducing or improving their ability of operating them. In addition, the summer course following the workshop, will be an opportunity to improve Atmospheric Modeling knowledge.

Subscriptions to the workshop will be accepted until February 18th, 2015, through the emails: ivwaqm@gmail.com
