CliSAP successfully finished in 2018. Climate research continues in the Cluster of Excellence "CLICCS".

HUSCO-Hamburg Urban Soil Climate Observatory (2010-2016, project completed)

A Monitoring Network to Determine the Influence of Urban Soils on Hamburg´s Local Climate

One of ten recording stations: Sealed-soil areas warm urban climates.
More evaporation: Green areas have a cooling effect.
Water balance: Soil characteristics influence water flows.

Every city has its own climate. And not only the geographical location but the city itself is an essential factor – for example, how closely packed the buildings are, or the extent of soil sealing. Green areas are especially important: Lawns, parks and streetside trees can cool urban climates. In the CliSAP research project HUSCO (Hamburg Urban Soil Climate Observatory, running from 2010 to 2016), meteorologists and soil scientists worked together to better understand the interplay between soil and atmosphere in urban contexts.

To do so, they especially focussed on the influence of the soil water balance in a variety of typical urban structures, e.g., sealed-soil inner cites, green areas and residential areas, on their immediate surroundings. The researchers’ goal was to quantify the effect of groundwater level and soil characteristics on evaporation, and therefore on the local urban climate, on the basis of multi-year measurements. Since the summer of 2010, a network of recording stations has provided data from throughout the Hamburg metropolitan area: Ten stations measure and record the most relevant meteorological parameters, e.g., air temperature and precipitation, while 17 ground stations monitor soil water balance and soil temperature down to a depth of 1.6 meters.

Even after the completion of HUSCO, the measurements in Hamburg continue. On the following pages, you will find the latest data, collected from stations in Hamburg’s Langenhorn (Green areas: LaG.; Residential areas: LaW.), Stellingen (Green areas: StG.; Residential areas: StW.), Rissen (Ri.), Wilhelmsburg (Green areas: WiG.; Residential areas: WiW.), Billwerder (Bi.), Neustadt (Neust.) and Hafen City (HC) quarters. Observations for the last two and last eight days are available.
