9812404CartonIn this project, the PIs will study interannual variability of the upper ocean for the period, 1940 - 1999. The Modular Ocean Model (MOM) will be used to provide "forecast" fields of Temperature, Salinity, and velocity fields. Then observations will be introduced through optimal interpolation or "nudging" techniques for data assimilation. Constraints are various historical data sets from the National Oceanographic Data Center (NODC), and comparisons will be made with independent data sets including the data sets from the World Ocean circulation Experiment (WOCE).The model will be improved by shifting to a multi-processor version,adding different wind products, upgrading the assimilation algorithm to include freshwater input, and other refinements. NODC scientists will focus on constructing repeat sections and time series, examining heat, mass, and freshwater budgets, and upgrading the data base with previously unavailable historical data. The NODC effort is supported by NOAA.

9812404Carton 在这个项目中，PI 将研究 1940 年至 1999 年期间上层海洋的年际变化。模块化海洋模型 (MOM) 将用于提供温度、盐度和速度场的“预测”场。 然后，将通过数据同化的最佳插值或“助推”技术引入观察结果。 约束条件为国家海洋数据中心（NODC）的各种历史数据集，并与包括世界海洋环流实验（WOCE）数据集在内的独立数据集进行比较。模型将通过转向多处理器版本，添加不同的风产品，升级同化算法以包括淡水输入，以及其他改进。 NODC 科学家将专注于构建重复部分和时间序列，检查热量、质量和淡水预算，并使用以前无法获得的历史数据升级数据库。 NODC 的工作得到了 NOAA 的支持。
