Ground-based fixed (urban, central Poland)

Warsaw site is a ground-based fixed, urban site in central Poland located in a city-center area with flat terrain. It covers 300 m² of indoor and outdoor laboratories hosting a large variety of instruments for characterizing the status, structure, dynamics, and composition of the atmosphere.

The site is characterized by fog during spring and autumn, large differences in mean temperatures between winter (-10 °C) and summer (+24 °C), relatively long periods with clear sky (mainly between April and September), frequently occurring Cirrus or deep-convection clouds in summer and presence of water and mixed-phase clouds in all seasons, low clouds dominate in colder months (November to February). There are periods with strong winds, while typical wind speed is of 3.5 m/s.

Observations of aerosol and clouds in urban areas using remote sensing techniques in a synergic way. Observations at Warsaw site show influences mainly from traffic, less form industry and constructions, with influence of domestic heating with fossil fuels and biomass burring sources in the city, and agriculture fields in the surrounding rural areas. The long-range transport of smoke and mineral particles affects the site both in upper air, and also in certain meteorological conditions can penetrate the Planetary Boundary Layer, affecting the air quality.
