Air quality in Cyprus is influenced by both local and transported pollution, including desert dust storms. We examined PM10 concentration data collected in different locations. The aim of the study is to identify the main natural sources of particulate matter PM10 in different locations of Cyprus; Nicosia, Kyrenia, Famagusta, by making some backward trajectories from these locations for the days with high concentration of PM10 at multiple heights for better interpretation of the impact of the dust arriving to Cyprus, 500 m, 1000 m, 1500 m above ground level during the year 2014. Monthly Clusters was applied as well to identify the origins and distributions of major trajectory groups. HYSPLIT (HYbrid Single Particle Lagrangian Integrated Trajectory) program was used to calculate trajectories and clusters, which is a system for computing air mass trajectories and complex dispersion and dispositions. North Africa is widely considered as the Earth's largest dust producing source, and the Sahara Desert is identified as one of the major source areas of windblown dust in the Northern Hemisphere, which was concluded in this study as well since the majority of trajectories of the days with high PM10 concentration are coming from north Africa and the Sahara Desert, with some few exceptions with different origins like the Golf area. It was also found that PM10 is transported to Cyprus more during winter which explains the high PM10 average concentrations during this season.

ABSTRACT Meteorological classification alludes to the identification of a number of distinct patterns, they can have their own effect on climate/weather-related environmental factors.
