文中利用海面温度和高度的卫星遥感数据，结合实测温、盐剖面数据，运用多种统计分析和数据同化方法，构建了南海海域动态三维温盐场。通过与实测独立样本温盐数据比较发现，构建的动态温盐场与实测温盐场吻合性较好。为了使其投入业务化运行，利用MATLAB平台开发研制了一套南海海域三维动态温盐场构建系统的人机交互软件，通过该软件简洁的界面操作，可以方便地构建海洋各标准层上空间分辨率为0.25°×0.25°的准实时(时间滞后约1-2d)的南海海域三维温盐场，同时实现了混合层深度、海水密度、声速等关键海洋环境参数的计算、查询及分析等功能，对保护南海权益、保障南海船只安全具有重要实用价值。

Based on remotely sensed sea surface temperature (SST) and sea surface height (SSH) data, the authors constructed temperature and salinity on three-dimensional grids in the South China Sea (SCS). The construction involved statistic analysis and data assimilation. Independent validations of the constructed temperature and salinity against in situ data revealed that the constructed temperature and salinity agree well with the in situ observations. For routine operations, a dynamically constructed three-dimensional temperature and salinity system was developed based on MATLAB. By interacting with a simple interface, the near real-time temperature and salinity in each standard layer can be retrieved and viewed on a 1/4-degree resolution in the SCS. In addition, other ocean environment parameters, such as mixed layer depth, water density and velocity of sound can also be provided by this system for further analysis and visualization.
