1992-2012年东南亚温盐流数据集

基于区域海洋模式ROMS，建立南海区域的海洋数值模式，并利用三维变分同化技术将南海区域多年的观测资料与模式产品进行融合，形成了1992~2012年东南亚区域的温盐流数据集。数据集覆盖范围为99°E~134°E，1°N~30°N，空间分辨率为1/10°，时间分辨率为6小时，垂向采用地形跟随的s坐标，分为32层。产品变量包括了温度、盐度和流场等。

Based on the Regional Ocean Modeling System (ROMS), a regional ocean numerical model for the South China Sea was established. Using 3-dimensional variational (3D-Var) data assimilation technology, multi-year observational data and model products over the South China Sea were fused to develop a temperature-salinity-current dataset for the Southeast Asian region spanning from 1992 to 2012. The dataset covers a spatial range of 99°E to 134°E, 1°N to 30°N, with a spatial resolution of 1/10° and a temporal resolution of 6 hours. The vertical dimension adopts terrain-following s-coordinates, which is divided into 32 layers. The product variables include temperature, salinity, ocean current field and other related parameters.
