  • Effect of sea breeze on air pollution in the Greater Athens Area. Part I: Comparison between field measurements and mesoscale model simulation for the MEDCAPHOT campaign


Field measurements and numerical results are used to explain the impact of the sea breezes on the photochemical smog episodes observed in Athens during the MEDCAPHOT campaign (September 12-14, 1994). The code used in this study is TVM/LCC, a prognostic mesocale model coupled with the chemical mechanism LCC. The model results are compared with ground, light detection and ranging (LIDAR) and aircraft measurements. The three days presented two characteristic summertime flow patterns for the Athens region. During September 12th and 13th, a strong synoptic wind from the north prevented the sea breeze formation and reduced the ozone levels. On September 14th, the weaker synoptic forcing allowed sea breeze development. High ozone concentration values occurred north and east of Athens.
