Ozone measurements at the mountain station Zavižan (Croatia) for 1997–2000

Abstract

Analysis of ozone concentrations measured at Zavižan, Croatia's highest altitude meteorological station (1594 m a.s.l.), during the spring and summer months of 1997–2000 shows that the actual new Croatian Air Quality standards are severely exceeded. Implication of this and similar findings from other elevated sites call for additional consideration of ozone behaviour at high altitudes in defining ozone standards.
