Project Status Year 1, 2, 3Developed,
improved, and validated spacebased moisture
transport. Applied to achieve continental water
balance over South America. Examined the
influence of midlatitude mesoscale ocean
processes on large scale high level atmospheric
energy and water balances. Year 4

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
