METEOROLOGICAL CONDITIONS PREVAILING DURING THE HYGRA-CD CAMPAIGN IN THE ATHENS BASIN: AN OVERVIEW
The HygrA-CD campaign was planned in the Greater Athens Area (GAA), Greece during summer 2014, when air mass convection is very likely to take place, as the atmosphere is still not totally dry. At this specific period of the year, we observed several Saharan dust outbreak events over Athens (i.e., synoptic winds from the south), but also air masses carrying mixtures of urban/continental and marine aerosols, due to the influence of the Etesian winds to the wind circulation in GAA (synoptic winds from the northeast).
In the present work, a general overview is given of the meteorological conditions prevalent during the field campaign. The main regimes present were Saharan dust events, Etesian wind flows, and continental transports. The overview includes a combination of remote sensing and in-situ observations, along with simulations from a mesoscale meteorological model (Advanced Weather Research and Forecasting, WRF-ARW).
