To meet the scientific community requirements European Space Agency (ESA) supports a project called Ocean Heat Flux (OHF) aiming at the development, validation, and evaluation of satellite-based estimates of surface turbulent fluxes, particularly derived from ESA satellite/mission EO data, of all the components of the turbulent fluxes over global ocean. One objective of OHF project is the development of a dedicated Flux Data Portal to access, share and foster the use of the reference data sets and flux products with the scientific community, and to enable easy inter-comparison between products and observations at various space and time scales. The portal, and other tools and datasets are available from OHF's website (http://www.oceanheatflux.org/)
