1. Project Title: Water and Energy Budget Study (WEBS)
Principal Investigator: John Roads
Science issue: Establish our current uncertainty in describing global to regional atmospheric and surface water and energy budgets..
Approach: Compare water and energy cycle data on common time/space grids.
Satellite-based data: GPCP, CMAP, NVAP,ISCCP, ISCCP FD, GRDC and EOS
Models: GLDAS Mosaic, NCEP Noah, NCAR CLM
Analyses: NCEP, ECMWF, Japanese reanalyses
Study Period: ISLSCP decade ( ), focus on Land, focus on later period for ocean means later
Project status:
Year 1 & 2 major finding –*Roads et. al 2007 provide and estimate of our current uncertainty in describing means of water and energy budgets.
Year 3 (now) – focus on seasonal variations and interannual monthly means
Year 4&5: switch land focus to ocean and then global means
and pull in other NEWS (&MERRA) data sets, begin focus on latter time periods.

Major Result to go in lower left side: Figures should not be too complex or busy – this example is probably the limit of acceptable complexity.
Land annual mean precipitation, P, evaporation, E, moisture convergence, MC, runoff, N, and the two combination closure and terms for the surface water, EW, and the atmospheric water vapor, EQ.
