Heat, water and momentum budgets over the ocean

具有高分辨率的准确海洋表面通量对于理解全球气候机制至关重要。然而，由于海洋观测数据数量极少且分布不均匀，利用海洋观测数据很难推算出这些通量。另一方面，卫星数据具有高密度、高分辨率和均质性的特点。因此，可以认为利用卫星数据可以得到准确的海面通量。最近，我们主要利用卫星数据构建了海面数据集。该数据集由日本海洋通量数据集利用遥感观测(J-ofuro)命名。数据集包括短波辐射、长波辐射、潜热通量、感热通量和动量通量等，此外还包括海面动态地形数据。辐射数据集覆盖西太平洋和东印度洋，因为我们使用日本地球静止卫星(GMS)来估计辐射通量。另一方面，湍流热通量是全球估计的。所构建的数据集用于许多科学研究，表明了其有效性。

Accurate ocean surface fluxes with high resolution are critical for understanding a mechanism of global climate. However, it is difficult to derive those fluxes by using ocean observation data because the number of 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 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). The data set 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. The constructed data sets are used and shows the effectiveness for many scientific studies.
