The overall aim of this project is to improve substantially the parameterisation of sea spray particulate fluxes for a wide range of environmental conditions. To meet US Navy needs for more accurate predictions of aerosol loadings, the underlying physical and chemical processes determining aerosol formation and evolution in the maritime environment must be defined. Progress is already being mad...

Accurate prediction of regional and global scale aerosol phenomena is crtical to military operations, especially over regions of interests such as Middle East. For this reason, the US Navy developed the first operational global aerosol model in the world. Yet the forecast accuracy is limited by lack of observations over ocean and other data-poor areas. The long-term goal of this study is to imp...

The variation of aerosol properties under polluted air masses advection was studied in a semi-rural site in South Italy, by means of SEM-EDX analysis performed on particles collected on 13-stages impactor filters. Radiometric measurements, HYSPLIT back-trajectories and NAAPS maps helped to choose four measurement days of polluted air mass circulation, two of them collected in the warm season (3...

Wildfire occurrence and severity in the Mediterranean region during summer season is increasing, being favoured by climate change-induced conditions (i.e., drought, heatwaves). Moreover, additional natural sources frequently impact this region, particularly Saharan dust intrusions. This study focuses on combined effect of wildfires air quality central Basin (CMB) 2017, an exceptional year for f...

Abstract. We present an Arctic aerosol optical depth (AOD) climatology and trend analysis for 2003–2019 spring summertime periods derived from a combination of multi-agency reanalyses, remote-sensing retrievals, ground observations. This includes the U.S. Navy Aerosol Analysis Prediction System ReAnalysis version 1 (NAAPS-RA v1), NASA Modern-Era Retrospective Research Applications, 2 (MERRA-2),...

Abstract. In a companion paper (Xian et al., 2022, part 1 of the study), we present an Arctic aerosol optical depth (AOD) climatology and trend analysis for 2003–2019 spring summertime periods derived from combination reanalyses, remote-sensing retrievals, ground observations. Continued previous discussion as second study, report statistics trends AOD extreme events using U.S. Navy Aerosol Anal...
