Analisi dei modelli validi per lo studio dei processi di deposizione secca e sui dati meteo previsionali dell’ECMWF

Risultato della ricerca: Book

Abstract

The DEIM's research group in collaboration with ENEA –C.R. Bologna, has performed the following activities: "Analysis of models to study dry deposition processes of pollutants in atmosphere onto urban surface", and "Preliminary study of compatibility between ECMWF forecast data and CALMET model". Regarding the first activity, a dry deposition model, based on electrical analogy, is developed to analyze complex phenomena,such as inertial impact processes and wind turbulence effects, that influence the transport of pollutants in the interface between urban canopy and quasi-laminar sublayer.The model allows the deposition rate assessment for particles with different diameters and various atmospheric conditions. A validation activity is performed by using some experimental data reported in literature for several Italian cities.With regard the second activity, the work is aimed to verify the compatibility of ECMWF forecast data with CALMET.This is a necessary step to build the CALMET data set input. Some empirical correlations as reported in literature as been identified to this purpose.It is to be noted that the ECMWF does not provide land use data and average cells height, required for CALMET modeling. Such data can be obtained through some pre-processors included in the CALMET software package
