1. Integrated Satellite Global Energy Data for Climate Studies
Investigator: Bing Lin
Project status:
Year 1 ~ 3 complete – Initial flux estimates and process analysis
Major components of climate energy cycle
@ TOA, surface & within the atmosphere
Year 4 (now) – Climatological energy data sets (ocean & land),
energy budget, balance, and uncertainty
Focus on river discharge, GRACE and other water data to obtain consistent results of
global water and energy balances
Inter-comparison of different data sets
Year 5 – Long-term climatology, relation and interaction between
energy and water, global heat transports
Science issue: Global energy balance will be analyzed 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: A-train satellite era ( ), and legacy data sets ( )
NEWS linkages: (pull, push, collaborate, external)
CERES, ISCCP, SRB, ERBE, RSS, 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
Global surface annual mean net heat budgets and their temporal variability for each ocean basins and continents estimated for the period of 1/1/ /31/2004. Bias errors in global means are about 13 W/m2, which is within the uncertainties of satellite estimates.
