WCRP update DCPP meeting, Barcelona, 12 May 2016 M. Rixen, mrixen@wmo WCRP update DCPP meeting, Barcelona, 12 May 2016 M. Rixen, mrixen@wmo.int Distinguished guests, ladies and gentlemen, dear colleagues, Thank you very much for the opportunity to provide you with a brief overview of a new initiative of the World Climate Research Programme: the WCRP Polar Challenge

(WCRP Strategic Framework 2005-2015). Mission & Objectives World Climate Research Programme supports climate-related decision making and adaptation planning by coordinating research required to improve climate predictions and understanding of human influence on climate “for use in an increasing range of practical applications of direct relevance, benefit and value to society” (WCRP Strategic Framework 2005-2015).

The broad aim of the WCRP is to coordinate and enhance these national efforts, in order to constitute a comprehensive international research programme implemented through concerted actions of participating institutions. The principal functions of the WCRP are then:  To initiate specific regional or global experiments for the study of particular phenomena or processes; To identify research priorities for recommendation to national scientific institutes and funding agencies; To propose and facilitate the implementation of relevant international research activities as required; To arrange for the rapid and effective dissemination of information on current results and new developments in climate research; To facilitate translation and interpretation of scientifically complex information into useful information and knowledge for practical applications in sustainable development and climate services; To support training and development of next generation of climate experts, especially for developing regions of the world.
