The aim of this study is to demonstrate that different methods of remote sensing for evaluating air pollution over urban area (Timisoara city), by using LIDAR combined with Sun Photometer data, completed with satellite images (Modis - Moderate Resolution Imaging Spectro-radiometer), are recommended for the extended understanding of complex phenomenon in the free atmosphere, further for quality of life and particularly for the determination of aerosols. These particles play a huge role in the energetic equilibrium of the different layers. Modis has the capability to monitor the air pollution over land, especially urban areas, which is the main source of aerosol particles caused by industry and urban traffic. LIDAR measurements offer a good temporal resolution and are considered limited only by the weather conditions (rain, snow or very cloudy days) compared with Sun Photometer, which is limited to daylight hours, but has the ability to identify the exact height of the aerosol layers. The advantage of the sun photometer is that it is able to indicate the optical parameters of the aerosols in the investigated area.

To reduce the air pollution and the deposition of pollutants which may lead to adverse impact upon public health and the environment, according the Gothenburg Protocol and the Directive 2001/81/EC on national emission ceilings for certain atmospheric pollutants (known as NEC Directive), the national emission ceilings were established for each Party and Member State concerned, representing the maximum amount of a substance which may be emitted annually at the national level. Actually, at the international and European level, the air quality policy framework is under review, in order to set the national emission ceilings by 2020 and to extend the environmental objective on long term till 2030, by coordination between air quality and climate change policies. In this context, the projections of national emissions of certain atmospheric pollutants - sulphur dioxide (SO2), nitrogen oxides (NOx) and fine particulate matter (PM2.5) - by 2030, represent a strategic tool for respecting the reporting requirements and also for assuring the Romania's technical support in the negotiations process for the NEC Directive review. The projections of emissions of certain atmospheric pollutants at the national and sectoral level involves the collection and processing the historical data, the identification of specific policies and measures included or planned to be included in the national legislation, setting the socio-economic development premises and modelling the evolution of emissions by 2030. The analyzed scenarios for emission projections were the scenario without measures and scenario with existing measures. The results of projections of emissions of certain atmospheric pollutants at the national and sectoral level were compared with the national emission ceilings by2020 and with the proposed ceilings by 2030.
