NASA Polar Program Kim Partington 27 April 2019 Polar Program

Key science questions Can we expect climate changes of consequence during the next decades and century, and what will be the causes for such change? Will polar ice sheets change in ways that would seriously affect global sea level? Is climate currently varying in ways we can understand and predict? How can the integrated effect of fast atmospheric, land and ocean surface processes be included in large-scale climate models? 27 April 2019 Polar Program

NRC DAAC Review NRC undertook review of the DAACs starting late 1997 and their recommendations have recently been reviewed at NASA HQ NSIDC praised Recommendations TBD: working more closely with ASF encouraging scientist working visits Dr. Asrar will provide formal response to NRC recommendations 27 April 2019 Polar Program

NRC Polar Products Review National Research Council Polar Research Board managing review (Sept. 1999-Sept. 2000) Review the direction and strategy for providing the polar research community with NASA data-sets (gaps, inefficiencies, technical issues, opportunities, etc.) pathfinder products, RGPS, polar altimetry data, POLES products, etc. input needed from PODAG and at least one site visit to NSIDC an opportunity to review where we are and to set a strategy 27 April 2019 Polar Program

NASA NRA - pathfinders and Interdisciplinary science NRA closed (9/27/99) Pathfinders focus more on science and not just data analysis (encourage return on investment with each pathfinder) Interdisciplinary science also covers some polar-related activities 27 April 2019 Polar Program

NRA - SAR and allied data analysis NRA getting signatures, NRA draft complete Issue to do with RADARSAT MoU and access to SAR data beyond November 2000 NRA designed to encourage use of derived SAR products (AMM-1, RGPS, Boreal forest data, etc.) as well as basic SAR products NRA also encourages synergistic use of additional data-sets (e.g. from NSIDC) 27 April 2019 Polar Program
