Abstract. Secondary inorganic aerosols (SIA) are major components of fine particulate matter (PM2.5), having substantial implications for climate and air quality in an urban environment. In this study, a state-of-the-art thermodynamic model has been coupled to the source dispersion photochemistry city-scale chemistry transport EPISODE-CityChem, able simulate pollutants on horizontal resolution 100 x m2, determine equilibrium between gas aerosol phases over Greater Area Athens, Greece, year...
Abstract In this study we present a methodological framework to obtain statistically downscaled high resolution climate projections over the Attica region in Greece. The relies on construction of local daily gridded dataset for temperature variables (maximum, minimum and mean temperatures) precipitation sums. To aim, mosaic data that includes observations derived from ground stations simulation, performed by Weather Research Forecasting (WRF) model, 1 year (1995) are blended using various...
Abstract. Land–atmosphere interactions govern the process of dust emission and transport. An accurate depiction these physical processes within numerical weather prediction models allows for better estimating spatial temporal distribution burden characterisation source recipient areas. In presented study, ECMWF-IFS (European Centre Medium-Range Weather Forecast – Integrated Forecasting System) outputs, produced with without assimilation Aeolus quality-assured Rayleigh–clear Mie–cloudy...

In this study, a state-of-the-art thermodynamic model has been coupled to the source dispersion photochemistry city-scale chemistry transport EPISODE–CityChem, which is able simulate pollutants at horizontal resolution 100 m×100 m, determine equilibrium between gas aerosol phases over greater Athens area,...
The attachment of positive and negative ions to settling spherical dust particles is studied. A novel 1D numerical model has been developed parameterize the charging process in presence a large-scale electric field. able self-consistently calculate modification atmospheric ion densities particles, consequent alteration electrical conductivity Moreover, estimates acquired charge on calculates force that applied them. Using observed size distributions, we find can acquire range 1–1,000...
Fine aerosol particles (PM2.5) in the mediterranean, urban area of Athens (Gr) during a contemporary year free anthropogenic activity restrictions (2019) is focus this study. The numerical atmospheric model system used (WRF/ Episode-CityChem) can describe local conditions (in 1 km resolution), with additional features to represent canyon pollutant dispersion and photochemistry intra-urban scale (100 m resolution). An extensive evaluation both models’ performance assessed through...
Windblown dust plays a crucial role in the Earth system, impacting climate, ecosystems, human activities, and health. The spatiotemporal evolution of plumes during transport is determined by wind, primary driver emission. In this study, we utilize outputs from ECMWF-IFS, assimilating quality-assured Aeolus wind profiles, to initialize simulations with WRF-Chem model. aim assess impact observations on modeling desert cycle. Focusing ASKOS/JATAC campaign September 2021 near Cabo Verde,...
<p>The available state-of-the art Regional Climate Model (RCM) simulations from the Euro-Cordex initiative have an horizontal resolution of about 12km which although is adequate for assessing regional climate change impacts still coarse studying in urban environment such as Greater Athens Area (GAA). To this aim we propose a hybrid dynamical-statistical downscaling approach that produces high resolution, order 1km, projections two future periods and under RCP scenarios. produce...
