Abstract

The diurnal variation of the Planetary Boundary Layer (PBL) structure and of the vertical profiles of the suspended particlates attenuation coefficient, are presented for the case of a semi-rural area near the north-eastern exit of the Athenian basin. These data were obtained using a ground-based LIDAR system operating at 355 nm and 532 nm, during the MEDCAPHOT-TRACE Campaign in the summer of 1994. The LIDAR system was pointing vertically and was operated during various air pollution (low up to severe photochemical episodes) and meteorological conditions (synoptic flow circulation, land-, and sea-breeze circulation). The LIDAR data are intercompared with meteorological and photochemical pollution data obtained by an instrumented aircraft overflying the Athens basin.
