ATMOSPHERIC STABILITY AND ATMOSPHERIC CIRCULATION IN ATHENS, GREECE

In the evaluation and study of atmospheric pollution reference is alwa ys made to the stability criteria. These criteria, usually represented as functions of different meteorological data such as wind speed and direction, temperature, solar radiation, etc., play a very important r ole in the investigation of different parameters that affect the build up of pollution episodes mainly in urban areas. In this paper an atte mpt is made to evaluate the atmospheric-stability criteria based on me asurements obtained from two locations in and nearby Athens. The atmos pheric stability is then examined along with the other meteorological parameters.
