Japanese Ocean Flux data sets with Use of Remote sensing Observations (J-OFURO)

Accurate ocean surface fluxes with high resolution are critical for understanding a mechanism of global climate. However, it is difficult to drive those fluxes by using ocean observation data because the number of in situ ocean observation data is extremely small and the distribution is inhomogeneous. On the other hand, satellite data are characterized by the high density, the high resolution and the homogeneity. Therefore, it can be considered that we obtain more accurate ocean surface fluxes by using satellite data. Recently we constructed ocean surface data sets mainly using satellite data. The data set is named by Japanese Ocean Flux data sets with Use of Remote sensing Observations (J-OFURO), and includes shortwave radiation, longwave radiation, latent heat flux, sensible heat flux, and momentum flux etc. Moreover, sea surface dynamic topography data are included in the data set. Radiation data sets covers western Pacific and eastern Indian Ocean because we use a Japanese geostationally satellite (GMS) to estimate radiation fluxes. On the other hand, turbulent heat fluxes are globally estimated.
