Local and regional air pollution characteristics in Cyprus: A long-term trace gases observations analysis.

Observations of key gaseous trace pollutants, namely NO, NO, CO, SO and O performed at several curb, residential, industrial, background and free-troposphere sites were analyzed to assess the temporal and spatial variability of pollution in Cyprus. Notably, the analysis utilized one of the longest datasets of 17 years of measurements (2003-2019) in the East Mediterranean and the Middle East (EMME). This region is considered a regional hotspot of ozone and aerosol pollution.
