March 2017: RGCM white paper on High Latitude Earth System Processes and Feedbacks
The RGCM program supports a significant research effort in high-latitude Earth Systems science. We worked with the greater RGCM science community to develop a white paper that presents a community view of priorities for high-latitude Earth Systems science. The white paper identifies four Grand Challenges in this area, and discusses goals, current capabilities, gaps, and research needs and opportunities within the context of these Grand Challenges. It was written as a deliverable of the RGCM PI meeting (November 2016).
