“…TCAM is a part of the Gas Aerosol Modeling Evaluation System (GAMES) [7] (Figure 2) including also: the meteorological pre-processor PROMETEO, that provides TCAM all the meteorological input fields in the correct spatial-temporal resolution, starting from the output of continental scale models; the emission processor POEM-PM [8]; a boundary condition preprocessor, that computes the boundary conditions for TCAM model in the application domain starting from the simulation of continental scale models. The emission fields are estimated by POEM-PM preprocessor starting from the 2004 CTN emission inventory [9].…”

Different Data Assimilation techniques have been formalized and applied in the context of complex nonlinear models, to describe chemistry and physics of the atmosphere. In the literature the main approaches presented are based on a) statistical interpolation (SI) techniques, including optimal interpolation methods, residual kriging methods, regression, etc... and on b) variational methods, as well as ensemble methods such as Ensemble Kalman filters (EnKF). The aim of all these methods is to combine various data sources, to provide an optimal estimate of the spatial distribution of a particular pollutant, considering the uncertainties in the measurements as well as in the models. This paper presents the Ensemble Kalman Filter (EnKF) scheme used to assimilate ozone measurements from ground monitoring stations in the simulations performed by an air quality model system. The Data Assimilation scheme has been applied to Northern Italy. Results show that the methodology highly improves the ozone estimation.

“…GAMES (Gas Aerosol Modeling Evaluation System) model 19 was used in this work to have a reference about vertical distribution of gases (the model provides concentration profiles along 4km of altitude, with 11 growing thickness levels). This modeling system is made of three main modules: (a) the multi-phase Eulerian 3D photochemical model TCAM (Transport Chemical Aerosol Model 22 ; (b) the meteorological pre-processor PROMETEO; (c) the emission processor POEMPM [16] specifically designed to produce present and alternative emission scenarios.…”

A simple method to determine the vertical distribution of a pollutant gas, namely NO 2 , by means of the spectral measurements obtained with a scan-DOAS spectrometer, is presented. The developed technique can be summarized as follows: i) a series of quasi simultaneous measurements in the zenith and in others directions allowing for the determination of the Slant Column Density of NO 2 for different elevation angles; ii) an active DOAS measurement for the determination of the NO 2 concentration at the ground; iii) a set of Radiative Transfer Model (RTM) calculation of the scattering distance from the spectrometer, for a set of visibility values; iv) a recursive procedure of profile calculation starting from the first measurement and subtracting the value of NO 2 Slant Column Density (SCD) retrieved from the measurement taken at the previous angle of sight. Measurements are carried out during summer 2007 in S. Pietro Capofiume (Bologna-Italy). The vertical distribution for NO 2 obtained with the above described method has been compared with the profiles calculated with the GAMES (Gas Aerosol Modelling Evaluation System) model. The results of this comparison show some differences between the modelled and the measured profiles, probably due to box approximations in RTM calculation for measured profiles and to the large pixel grid (about 10x10 km2), for model evaluation.

The chemical and size characterisation of aerosol in northern Italy was investigated by means of transport chemical aerosol model (TCAM) multiphase model longterm simulations performed within the frame of the CityDelta-CAFE exercise. The results show a high contribution of secondary inorganic compounds, in particular far from the Milan metropolitan area and in the large rural area of the Po valley where the major chemical fractions are ammonium and nitrates. The sulphate contribution is quite similar throughout this region, with the exception of areas close to SOx point emissions. Primary PM and organic compounds fractions, on the other hand, are greater close to major urban areas, in particular the Milan metropolitan zone. This work also presents a seasonal characterisation analysis of physical and chemical aerosol features. The results show that in winter, due to domestic heating emission of NOx and low temperatures, which favour the formation of secondary nitrate and organic aerosol, the PM10 and PM2.5 concentrations are higher than those in summer, in agreement with experimental data presented in several studies focussing on the same region.
