全球海洋再分析数据
GLORYS12V1产品是CMEMS全球海洋涡旋分辨率（1/12°水平分辨率，50个垂直层次）再分析产品，涵盖了高度计数据（从1993年至今）。该产品主要基于当前实时全球预报CMEMS系统。模型组件是NEMO平台，表面驱动使用ECMWF ERA-Interim和最近几年的ERA5再分析数据。观测数据通过简化的卡尔曼滤波器进行同化。沿航迹高度计数据（海平面异常）、卫星海表温度、海冰浓度以及原位温度和盐度垂直剖面被联合同化。此外，3D-VAR方案对温度和盐度的缓慢变化的大尺度偏差进行校正。

Global Ocean Reanalysis Data
The GLORYS12V1 product is a CMEMS global ocean eddy-resolving reanalysis product with a 1/12° horizontal resolution and 50 vertical levels, covering altimeter data from 1993 to the present. This product is primarily based on CMEMS' current real-time global forecasting system. The model component is built on the NEMO platform, and its surface forcing uses ECMWF ERA-Interim and ERA5 reanalysis data from recent years. Observation data is assimilated via a simplified Kalman filter. Along-track altimeter data (sea level anomaly), satellite sea surface temperature, sea ice concentration, and in-situ vertical profiles of temperature and salinity are jointly assimilated. In addition, the 3D-VAR scheme corrects slow-varying large-scale biases in temperature and salinity.
