Email: harry@env.meteo.noa.gr Abstract The present study estimates the atmospheric stability for the Athens area based on Pasquill's formulation. The results are limited to examining the stability categories during the months of January (mid-winter term) and July (mid- summer term). These stability classes are examined from a 44-year database consisting of hourly values of wind speed and direction, solar insolation and cloud cover. This data is regularly recorded at the National Observatory of Athens located near the city centre. The results of the work consist of diagrams with mean monthly stability class values during January and July in the period 1953-1996 and the mean
