SUDPLAN Services Available after FP7 and their Possible Future Use

This paper gives an overview on the software results of the SUDPLAN project. The results can serve as a technical basis for the integration of climate change effects in urban planning, including access to adequate climate change information. End-users provide local data to improve the downscaling of climatic and environmental variables, based on regional climate model output to deliver projections of environmental conditions in the right scale for the local planning process. Downscaling is performed by a set of Common Services that deliver data describing rainfall intensity, frequency and duration; hydrological conditions; soil moisture and surface water resources; and air quality. The urban scale projections provided may be used to assess urban storm water flooding and sewer system capacities, river flooding, and citizen health. The client side functionalities necessary to integrate, visualise and support local climate change aware analyses are provided by the Scenario Management System. The general approach, the downscaling result quality, and the soundness of the technical developments are demonstrated by four representative case studies in Stockholm, Wuppertal, Linz and Prague. A large part of the results is available as Open Source software.
