This activity was carried out within the framework of a joint R&D Contract awarded to IIE-Mexico and Elettronica Spa-Italy by the European Community, DG XII. Surface Layer parameters were obtained using ground level measurements. The evolution of the mixing layer depth was estimated using some well-known prognostic models (Encroachment and Gryning- Batchvarova models). Mixing height estimates were compared with observed ones obtained by elevated measurements. The paper presents a short description of the meteorological campaign, the meteo processing m
