On the atmospheric stability in the Athens Basin

摘要

Atmospheric Stability is one of the most significant factors in studying dispersion conditions in an area. The Athens Basin is characterized by major environmental problems due to physiographic characteristics and pollution sources located in and around it. The study of Stability might give useful hints about the local circulation systems. For the study of Atmospheric Stability in Athens a data base has been constructed, from two years' measurements of stability factors, at two locations in the Athens Basin, one in the National Observatory of Athens and the other in the Nuclear Research Center "Democritos". This data base was used to create the stability classes according to Pasquill-Gifford methodology. Based on the above measurements, a mass consistent model (NOABL) was applied in Greater Athens Area in order to describe the mean flow field for some of those stability classes.
