A central task of this project is to identify the needs of the different user groups and to develop such highly aggregated numbers and figures. The knowledge and needs of the users are very divers: some users need the data provided directly, others rely on heavily aggregated numerical values or simplified figures. Users will be involved in the design of the portal to promote user-friendliness and uptake by new users. It will cover the different time horizons of climate predictions from monthly outlook to decadal climate predictions and climate projections indicating global climate change characteristics for Germany. This web-based system will be easily accessible and understandable to attract unexperienced users but also users with climate service background. To address international users as well, the website will also be available in English language. The website will be integrated into the DWD internet site and will consider the Copernicus guidelines for websites, provided that they do not contradict the corporate design specifications of the DWD. Thus, the website implements the national implementation of C3S climate services in Germany.

It implements a national downstream product focusing on German users and will be presented in German language. Built on the Copernicus Climate Change Service (C3S), a seamless web information portal will be set up. There exists an enormous interest in society, politics, public, business and, in consequence, the need for an early and reliable provision of evaluated and reliable monthly to centennial trends of possible future climate development and information on strength and frequency of upcoming extreme climate events.
