Projektinformation
Beskrivning (abstrakt)
The Enviro-PEEX(Plus) overall objectives are to analyze importance of the meteorology-chemistry-aerosols interactions and feedbacks and to provide a way for development of efficient techniques for on-line coupling of weather prediction and atmospheric chemical transport via process-oriented parameterizations and feedback algorithms, which will improve the numerical weather prediction, climate and atmospheric composition forecasting in the PEEX domain.
The project tasks include modelling and analysis: (i) for case studies with physical and chemical weather downscaling forecasting to evaluate sensitivity of aerosol effects on meteorology, atmospheric composition and climate; (ii) for episodes for weather, climate and air quality applications to evaluate possible effects; and (iii) for testing parameterizations, meteorological and chemical initial and boundary conditions, and chemical data assimilation. The ECMWF computational resources with data archives will be used to experiment with developed components of the modelling systems and evaluate their performance and sensitivity, intensive testing and validation.
The expected application areas and expected results are for improving: (i) coupling of aerosols and chemistry aiming towards better description of aerosols and relevant microphysical processes, and their effect on radiative fluxes and clouds; (ii) understanding and ability in prediction of chemical and physical processes related to the formation and growth of atmospheric particles; (iii) weather prediction with short-term feedbacks of aerosols and chemistry on meteorological variables; and (iv) atmospheric composition forecasting with two-way feedbacks between aerosols/chemistry and meteorology.
The Universities and research organizations from Finland, Denmark, Italy, Russia, Turkey, and Ukraine participate in this project led by the UHEL-INAR.
