Near Real-Time Aerosol Predictions During the First Citizen Observatory Campaign in Greece
by Athanasopoulou, E. and Speyer, O. and Apostolopoulou, S. and Papageorgiou, S. and Amiridis, V. and Gerasopoulos, E.
Abstract:
This study complements the results from the first citizens' observatory campaign focusing on aerosol monitoring in 11 European cities (including Athens) during September 2015 (iSPEX-EU project). Instantaneous columnar aerosol measurements, obtained by citizens with their mobiles, are currently under process to produce aerosol optical thickness data. In parallel, high-resolution model simulations (COSMO-ART) near real-time were performed over Greece. Supplementary data from the regulatory AQ network of Athens reveal low surface PM2.5 values over Athens—reproduced by the model application—with prolonged and frequent Saharan dust intrusions. The direct radiative effects of low PM2.5 concentrations are calculated up to −16 W m−2 at the urban core, with a subsequent temperature decrease up to −0.4 K (surface values).
