Abstract
Aerosols are important elements of the atmosphere. They influence the energy balance of Earth's surface, the water cycle and the atmospheric chemical reactions. Knowing the amount, vertical distribution and optical properties of aerosols in the atmosphere is an important issue due to their complex role in radiation balance of Earth's surface. The optical properties of aerosol strongly depend on its origin and air humidity. The impact of aerosol on optical properties of the atmosphere will be estimated on the base of LIDAR and meteorological measurements. The measurements will take place on location Otlica, near Ajdovšcina. The LIDAR system was developed on Polytechnic Nova Gorica and will be improved during the project. The meteorological measurements will be taken with automatic weather station Vaisala MAWS. The path of air particles before reaching the area of measurements will be traced by using back trajectories. This will enable the estimation of aerosol origin and the investigation of potential relationship between the origin of aerosol and its impact on optical properties of the atmosphere. Simultaneously a mobile LIDAR system will be developed. It will enable the measurements of the aerosol amount and its optical properties in special conditions (strong temperature inversions, Saharan dust outbreaks, forest fires, etc.) on arbitrary locations. The main goal of our study is to establish the LIDAR measurements of optical properties of the atmosphere in relation to the vertical distribution of aerosol, and to investigate the potential relationship between aerosol origin and its influence on the optical properties of the atmosphere. The LIDAR measurements, which will continue also after the project conclusion, will be a new acquisition for ecological and meteorological measurements on the area of Slovenia.
