Schimbarile climatice si calitatea aerului reprezinta principala problema globala. Teledetectia masoara
poluarea la distanta si este o tehnologie noua pentru monitorizarea poluarii aerului dezvoltata la Universitatea
„Politehnica” din Timisoara. In aceasta lucrare sunt folosite urmatoarele instrumente de teledetectie: LIDAR si
fotometru solar. Ambele sunt foarte importante si folositoare in cercetarea atmosferica, deoarece dau informatii
despre diversi parametri atmosferici, care au o rezolutie spatiala si temporala ridicata. Aceasta lucrare prezinta un
episod de poluare cu praf desertic, deasupra orasului Timisoara, in 26 aprilie 2011, provenit din regiunea de nord a
Africii. Intruziunile de praf desertic au fost observate deasupra Romaniei folosind masuratorile de la sol (cu sistemul
LIDAR si cu fotometru solar) si calculand traiectoriile maselor de aer (modelul HYPLIT).

Abstract
Climate change and air quality represent today global problems of mankind. Remote sensing witch
measurement of pollution from distance is a new and challenge technique for air pollution monitoring,
developed at the “Politehnica” University of Timi?oara. Instruments which are used in this paper are LIDAR
and sun photometer. Both instruments are very useful in atmospheric research because it provides
information on various atmospheric parameters, with high spatial and temporal resolution. This paper
presents a pollution episode with desert dust, over Timi?oara city, originated from Africa during April 26,
2011. Desert dust intrusions were observed over Romania by using ground-based measurements (from LIDAR
system and sun photometer) and air mass trajectory (HYSPLIT model).
