Rezumat
Scopul acestei lucrari este de a identifica principale zonele geografice responsabile pentru
cresterea nivelului de PM10 in doua orase (Bucuresti, Europa de Est si Szeget Europa Centrala si de Est).
Traiectoriile inapoi (modelul HYSPLIT) sunt cluster folosind metrica Mahalanobis, in scopul de a determina
care regiuni au concentratii ridicate de PM10. In aceasta lucrare au fost analizate valorile mediei zilnice de
PM10, precum si datele zilnice meteorologice luate din ambele orase pe o perioada de cinci ani (2004-2008).

Abstract
The aim of this paper is to identify the key geographical regions responsible for increase
particulate matter (PM10) levels in two cities (Bucharest, Eastern Europe; and Szeged, East-Central Europe).
Backward trajectories (HYSPLIT model) are clustered using the Mahalanobis metric in order to determine
which regions imply high PM10 concentrations. In this paper was analyzed daily mean PM10 data as well as
daily meteorological data taken for both cities for a five years period (2004-2008).
