The atmospheric station Lutjewad (at 6º 21’ E, 53º 24’ N) has been newly developed as an aerosol station within the Dutch Ruisdael observatory and lies on the coast of the Wadden Sea. Measurements of aerosol size distribution, chemical composition and cloud condensation nuclei are available since July 2021. Aerosol concentrations and properties showed distinct variations with air mass origin, meteorological conditions, season and time of the day. The location provides a unique opportunity to study European pollution outflow to the North Sea, which leads to strong increase in non-refractory PM_2.5 mass (on average 16.62±7.75 µg m^-3 compared to 2.52±6.19 µg m^-3 during air flow from the clean North Sector). The particle size distribution data show very frequent new particle formation events, often early in the morning hours and regularly the new particles grow to CCN sizes. This presentation will give an overview and statistical summary of the first 1.5 years of measurement at the station.
