1. Integrated satellite global energy data sets for climate analysis and modeling studies Investigator: B. Lin (bing.lin@nasa.gov) Project status: Year 1 & 2 complete – initial flux estimates and process analysis http://ams.allenpress.com/archive/1520- 0442/19/22/pdf/i1520-0442-19-22-5745.pdf http://www.agu.org/journals/gl/gl0714/ 2007GL029768/2007GL029768.pdf Year 3 (now) – focusing on 2003-2005 global energy budgets Using GRACE and other water data to cross-check energy balances. inter-comparison of different data sets Year 4&5: focus on long-term climatologies, analyze energy transports of climate systems, test model results Science issue: Global energy budgets will be balanced using combined NASA satellite data sets. Approach: Quantify uncertainties in the integrated global energy data; cross-validate climate energy components using both energy and water cycle satellite observations, and analyze energy and water processes Satellite-based data: HOAPS,CERES, ISCCP, and SRB Models: GLDAS Other data: GPCP2, GRACE, AIRS, MODIS, SSM/I Study Particulars: EOS satellite era (2003-2005), and legend data sets (1985-2005) NEWS linkages: (pull, push, collaborate, external) CERES, ISCCP, SRB, and HOAPS satellite data Rodell – GLDAS & GRACE products Adler – GPCP2 Liu and Wentz – Moisture transports Bosilovich – Model evaluations Schlosser – Water cycle project L'Ecuyer , Olson, Fetzer, Wielicki McFarlane and Dong– Profiles GEWEX LandFlux working group latitude Annual zonal mean atmospheric and surface heat budgets (W/m2) from radiation, latent and sensible heat flux components. Bias errors in the global annual mean data are listed. Updated: October 23, 2007
