An environmental experiment over Athens urban area under sea breeze conditions
Kambezidis, D., Peppes, A. and Melas, D.
[abstract] Instrumental and technical details as well as results from ATHens Internal Boundary Layer EXperiment (ATHIBLEX) are presented in this paper. This experiment was performed during June 1989 and June-July 1990. The aim of ATHIBLEX was to study the IBL formation over Athens urban area under sea breeze conditions and its association with the city environmental problems. The results show a well established IBL over Athens basin. A slab model is adopted to estimate IBL heights at positions where no measurements were taken. The orograhic effect of Athens basin on the wind profiles is also demonstrated. u′-, v′- and w′-power spectral densities from a uvw propeller anemometer installed 4500 m downwind of the shoreline on the top of a hill 107 m a.m.s.l. exhibit the -5/3 law.
