Description: The primary goals of this project are to improve knowledge of the chemical composition, optical properties and source of particulate matter including the - Assessment of the chemical composition of particulate matter (PM1) and quantification of the sources contributing to the organic fraction in Romania in comparison to Switzerland and other European countries. - Integrated assessment of particulate matter concerning their optical and chemical properties combining LIDAR and in-situ measurements. The main in-situ measurement tools will be Aerodyne aerosol mass spectrometers (AMS) including the capability to measure the composition of single particles in addition to the average concentrations. A multiwavelength aethalometer and 14C analyses complement the measurements to provide high time resolution information on sulfate, nitrate, ammonium, chloride, organic matter (OM) and black carbon (BC). The sources of OM and BC will be assessed with the measurement data using advanced statistical methods. A light scattering module for the AMS and an aethalometer will be acquired in the project to complement the existing measurement capabilities in Romania. The combination of these 3 methods, including especially the single particle analyses, will be unique world-wide. The in-situ measurements will be accompanied by state-of-the art lidar systems providing information on the scattering properties of particulate matter and the vertical structure of the boundary layer and in general the vertical distribution of particles. Two field campaigns in Romania and Switzerland are planned during the project - A winter campaign in Romania and Switzerland with all instrumentation and Lidar measurements in Romania. This campaign will be coordinated with a pan-European field campaign organized by EMEP to improve the information on air pollutants for model evaluation. - A summer campaign in Romania to compare the conditions, concentrations, sources in summer and winter - A summer campaign in Switzerland including a Romanian Lidar making use of the high-altitude station Jungfraujoch for direct comparison of in-situ and remote measurements of optical properties of aerosols including in-situ chemical composition and size distribution. The project will lead to - Know-how exchange from Switzerland partners to Romania concerning AMS operation - Know-how exchange from Romania to Switzerland concerning LIDAR applications and their integration with surface measurements - Increased visibility for Romanian scientists at the European level, through participation on important field campaigns and publication of peer-reviewed articles in high-impact scientific journals. - Assessment of the vertical distribution of particulate matter and its chemical composition in two locations with different characteristics (Magurele-Romania and Payerne-Jungfraujoch in Switzerland)(...)
