Abstract

Evaluation of PBL parameters from GPS-MET data L. Beccaceci*, R. Cocci GrifonP & G. Passerini^ 1 General Impianti S.r.l. Mole di Maiolati (AN), Italy ^Dipartimento di Energetica, Ancona University, Ancona, Italy Abstract GPS-MET is a meteorological analysis tool based on the Global Positioning System network of satellites. In the troposphere, GPS-MET data can be used to describe the vertical profiles of main meteorological variables. Data from a GPS occupation measurement system can lead to significant improvements in air pollution studies since, basically, meteorological pre-processors of dispersion models must be initialised with temperature, moisture, mixing height, and wind data. Amongst these, the mixing height, namely the thickness of the boundary layer, is one of the most important parameters governing the dispersion of atmospheric pollutant The aim of this paper is to describe the methods which can be used to evaluate PBL parameters from GPS-MET data. 1 Introduction Studies
