OAFlux: Objectively Analyzed air-sea Fluxes for the global oceans.

"The OAFlux project aims to provide consistent, multi-decade, global analysis of air-sea heat, freshwater (evaporation), and momentum fluxes for use in studies of global energy budget, water cycle, atmosphere and ocean circulation, and climate. The OAFlux project is so called because it applies objective analysis approach to take into account data errors in the development of enhanced global flux fields. The objective analysis denotes the process of synthesizing measurements/estimates from various sources. Such process reduces error in each input data source and produces an estimate that has the minimum error variance. The OAFlux project uses the objective analysis to obtain optimal estimates of flux-related surface meteorology and then computes the global fluxes by using the state-of-the-art bulk flux parameterizations.
