During the period of 01 August 2014 to 31 May 2015 the maximum entropy production MEP model, now formulated for all land-cover types including bare soil, canopy, water, snow and ice, was expanded to modeling global surface energy budget, fluxes and greenhouse gasese.g. carbon dioxide and methane fluxes, ocean freshwater fluxes, regional crop yield among others. An on-going study suggests that the global annual evapotranspiration ET over oceans may be significantly lower than previously thought. The MEP model parameterized turbulent transfer coefficients result in good estimates of surface fluxes of greenhouse gases, a finding pointing to a new method of modeling the global carbon budget using remotely sensed data. A new model of ocean freshwater fluxes derived from sea surface salinity provides independent estimates of ocean ET for cross-validation of the MEP modeled ET.
