In this study, EC and OC at 4 m elevation and EC at 230 m elevation showed a similar
seasonal pattern with higher values in winter and lower values in summer. OC, measured
at 230 m height showed an opposite behavior with slightly higher values in spring and
summer, probably related to the increased contribution of secondary organic carbon
(SOC). Concentrations were generally higher at 4 m, where there was also a better
correlation between EC and OC, suggesting a greater influence of local sources near the
surface.
