1 Integrated use of remote sensing and Lidar techniques for the study of air pollution and optical properties of the atmosphere in Cyprus > > The project ILATIC "Integrated use of remote sensing and lidar techniques for the study of air pollution and optical properties of the atmosphere In Cyprus" (PENEK/0311/05) is co-funded by the Republic of Cyprus and the European Regional Development Fund of the European Union through the Research Promotion Foundation. REPUBLIC OF CYPRUS EUROPEAN UNION

2 > PARTNERS > GENERAL This project concerns the study of aerosol optical properties of the atmosphere in Cyprus using remote sensing and lidar techniques. It is a 30-month project commenced in April HO: CUT Department of Civil Engineering and Geomatics (HO) - Cyprus University of Technology PA1: NKUA Department of Environmental Physics-Meteorology, National and Kapodistrian University of Athens (NKUA: PA1) PA2: NOA The Institute for Environmental Research and Sustainable Development (IERSD) PA3: NTUA The LASER REMOTE SENSING UNIT (LRSU) INOVATION-ORIGINALITY: In Cyprus there are both anthropogenic and natural source of air pollution. Aerosols are produced from the industrial activities as well as from the Saharan desert during the dust intrusion happening all year long. Despite the frequent desert dust transportation, other sources affect the study area. A statistical analysis of vertical aerosol optical properties that have never happened in Cyprus will comprise not only a reliable tool for the scientific community but also for the governmental authorities in order to approve the main origin of air pollution in Cyprus. The overall objective of this proposal is the creation of database concerning the optical characteristics of aerosols using ground-based measurements and remote sensing data as well as the seasonal evolution of Planetary Boundary Layer depending on the meteorological conditions, in order to retrieve an algorithm appropriate for monitoring particle pollution and extracting information for the atmospheric properties. These atmospheric properties will comprise the basic tool for the atmospheric corrections in the remote sensing imagery. Specifically will be created a database taking in account either overall column aerosol properties or vertical distribution of them. PA4: CDM Cyprus Department of Meteorology Ilatic >1 Ilatic >2

Development of a statistical significant database for the aerosol optical properties concerning not only the ground-based data but the vertical distribution of them, for the first time in Cyprus. 2. Assessment of the PBL height retrieved from lidar and HALO profiling. 3. Retrieval of the PBL height under different meteorological conditions using classification techniques. 4. Statistical analysis (annual variation) of Planetary Boundary Layer (PBL) and Dust Layer (DL) using lidar data. 5. Development of a new integrated algorithm for the continuous monitoring of particulate pollution and retrieving atmospheric parameters necessary for the satellite atmospheric corrections.

9 > CREATE Campaign: Cyprus Regional Experiment on Aerosol Transport and Exchange 44 days simultaneous measurements in the coastal area of Limassol (August - October 2013) During the CREATE Campaign the comprehensive measurements from HALO and Limassol depolarization lidar provided a perfect data set in order to determine the structure and the evolution of PBL and FT within a typical day, for the analysis of aerosol distribution under the influence of sea breeze effect and the better understanding of the PBL dynamics. Additionally the campaign s dataset gave useful information and knowledge for aerosol/cloud interaction processes.
