More about us
More than half of the world's population live in cities. By 2030 this figure will rise to 70%, with Asia and Africa showing the strongest development. Cities are confronted with the following problems: anthropogenic climate change (due to the increasing emission of greenhouse gases) and the urban heat island effect (UHI - Urban Heat Island, as a result of urbanisation and changes in landscaping). These effects can either reinforce or mitigate each other. UHI and climate change both lead to higher temperatures and thus to increased thermal stress on the population, animals and plants in urban areas.
The working group "Urban Climate and Urban Monitoring Network" investigates the interaction between microclimates (temperature, humidity, precipitation and wind) and urbanisation under the influence of climate change and their impact on public health. Data from measurement campaigns, short-term stations and the Berlin city monitoring network play an important role. Remote sensing and modelling of climatological parameters in cities also play an important role. The aim is to achieve sustainable urban development and adaptation to climate change. The working group has many years of experience in the application of high-resolution climate models, which include dynamic and statistical downscaling as well as micro-climate simulations. The spatial resolution can reach up to 1m. The UHI effect is also modelled in these dimensions.
The Berlin city monitoring network consists of 11 stations distributed over the entire city area. These stations report measurement values every minute to the central office at the Institute of Meteorology. In addition, there is the data from the 24-hour weather observation at the Institute.
