R3 represents an innovative endeavor to provide climate services at local to regional scales in Norway. Norway is characterized by large regional differences in geography and climate. As such, obtaining credible projections of climate change at local scales has been, and remains, extremely challenging. R3 takes an integrated approach that will encompass a range of outcomes and represent detailed information about changes in precipitation, temperature and extremes. R3 will also address the so-called "usability gap" between climate change research and decision-making. The need for improved, robust and credible estimates of local-scale climate change in decision-relevant contexts is pressing both within Norway and abroad.
