J-OFURO3 is a satellite-derived dataset of surface flux between the atmosphere and the ocean, and physical parameters related to the flux. This is the third generation dataset for J-OFURO project with many improvements from previous versions. J-OFURO3 is characterized by the use of multi-satellite data for the estimation of various parameters, and provides a dataset on surface flux over the oceans except for sea ice areas, along with relevant physical parameters including sea surface temperature, surface wind speed, and surface air specific humidity, as daily mean values in 0.25 degree grids.

The table summarizes the comparison of major features of the current dataset against past datasets.
For further detailed information will be available in the "Document on details of J-OFURO3 data set".

Japanese Ocean Flux Data Sets with Use of Remote Sensing Observations (J-OFURO) is a research project on air-sea flux in the Earth system. We develop and provide datasets on surface heat, momentum, and freshwater fluxes over the global oceans with the exception of the sea ice areas using a lot of observational information obtained by various earth observing satellites. Currently, we are providing the third-generation dataset: J-OFURO3 on this web site with even more improvements from previous datasets.

J-OFURO3 data set provides a numerical data set of air-sea fluxes, along with relevant physical parameters including sea surface temperature, surface wind speed, and surface air specific humidity. A daily mean on 0.25 degree grids data set for 1988-2013 is going to be constructed in this project.

The latest information about the data set and project, the full documents, and links to the data set will be available on this web site.


An example of J-OFURO3 net heat flux

An example of J-OFURO3 data set: long-term mean of surface net heat flux (NHF, W/m^2) obtained from V1.0. Average period is 2002-2013. Positive value means upward heat transport.
