J-OFURO, version 2

Japanese Ocean Flux data sets with Use of Remote sensing Observations, 0.25 degree

Ocean actively changes heat, water and momentum with atmosphere at ocean surface. The exchanged heat, water and momentum are transported by general ocean and atmospheric circulations at a global scale. Since the exchanging and transporting processes play important roles for global climate, it is quite important to estimate the fluxes between atmosphere and ocean and those transported by ocean and atmospheric circulations in order to understand the mechanism of changes in global climate. However, it is difficult to globally estimate these using in situ measurement data such as ship observation because such data are extremely sparse in time and space. We can obtain considerably homogeneous data with high resolution using analysis and satellite data. Therefore, it is considered that analysis and satellite data are suitable for obtaining globally covered fluxes between ocean and atmosphere. The J-OFURO group at School of Marine Science and Technology, Tokai University have constructed ocean surface flux datasets by mainly using satellite data. Recently, they reconstructed surface heat and momentum flux data in J-OFURO to represent version 2 (J-OFURO2). In version 2 dataset, several problems associated with version 1 dataset have been solved. You can use J-OFURO2 data freely for scientific use.
