AI-Generated Summary
The Urban Climate Observatory (UCO) Berlin is a long-term, open scientific infrastructure operated by the Chair of Climatology at Technische Universität Berlin. Led by Dr Fred Meier, the UCO serves integrative research on urban weather, climate, and air quality, providing the detailed environmental data needed for evidence-based urban planning and climate adaptation in Berlin.
The observatory comprises three complementary measurement components. The Urban Climate Observation Network (UCON) uses automatic weather stations for ground-level measurements of atmospheric variables including air temperature, relative humidity, air pressure, global radiation, wind, and precipitation at various locations across Berlin. Since 2015, the network has been supplemented by systematically collecting freely available data from Netatmo citizen weather stations, creating a crowdsourced monitoring layer with high spatial granularity.
Meteorological towers at locations including Rothenburgstraße and the TU Berlin Campus Charlottenburg quantify the turbulent exchange of sensible heat, water vapour, and carbon dioxide using eddy-covariance systems at various heights. Radiation sensors record short-wave and long-wave radiation fluxes, providing detailed energy balance data for different urban surface types.
Ground-based remote sensing instruments study the urban boundary layer in three dimensions. Doppler wind LiDAR, microwave radiometers, and ceilometers measure vertical profiles of wind speed and direction, air temperature, water vapour, clouds, and aerosols. An X-band Doppler weather radar with dual-polarisation capability is currently under construction.
For smart city practitioners, the UCO is relevant because it provides the granular, long-term environmental data that underpins urban heat island mapping, air quality modelling, green infrastructure planning, and climate adaptation strategies. Its integration of citizen science data demonstrates how community participation can enhance scientific monitoring networks.
