The work is organized in six major tasks covering review of instrument requirements, set-up of the airborne and ground-based components, their testing during intensive campaigns and data analysis. Two observation campaigns focusing on greenhouse gases, gaseous pollutants and aerosols will be organized in order to assess the RAMOS capability to respond fast and to provide independent valuable data for satellite mission’s validations. One of the campaigns, focus on NO2, SO2, H2CO and aerosols, will study the city influence on gaseous pollutants and agriculture area influence much more pollutant free. While the second campaign focusing on greenhouse gases will demonstrate both the capability to use the Romanian Atmospheric Observation System in unfamiliar conditions and the lower limit of the measurements techniques.
