1. Project Title: Oceanic Influence on Global Water/Energy Cycle
P.I.:W. Timothy Liu; Co-I: Wenqing Tang and Xiaosu Xie
Science Issue:Characterization and understanding of oceanic influence of global water/energy cycle was hampered by sparsity of data
Approach:Develop and improve methodology of spacebased retrieval of moisture transport, evaporation, and momentum flux, over ocean and relate them to global water/energy cycle
Satellite-based Data: QuikSCAT, AMSR-E, AIRS, ISCCP, TRMM, MISR, AMSU
Other Data: ECMWF,ECCO, Lagrangian drifters, river discharge,Argos
Study Period: 2000 to present
Project Status:
Year 1 & 2:Developed, improved, and validated spacebased moisture transport. Applied to achieve continental water balance over South America
Year 3:Study cloud-radiation feedback over water front. Improve evaporation retrieval
Year 4 & 5:Water/energy balance over global ocean
