Estimating the Circulation and Climate of the Ocean (ECCO) data products

Estimating the Circulation and Climate of the Ocean (ECCO) consortium was established in 1998 as part of the World Ocean Circulation Experiment (WOCE) with the goal of combining a general circulation model (GCM) with diverse observations in order to produce a quantitative depiction of the time-evolving global ocean state. This dataset includes data products from the original ECCO1 project and the subsequent ECCO-GODAE (Global Data Assimilation Experiment) and GECCO (German ECCO).
There are four groups of data:
1) Monthly, 10-day, daily or 12-hourly ocean model state, adjusted forcing fields and mixing coefficients
2) Observational data sets as they enter the optimization
3)Misfits between model output and available observations, as computed by the model cost/objective function
4) Past published estimates

海洋环流与气候估算（Estimating the Circulation and Climate of the Ocean, ECCO）联盟于1998年成立，作为世界大洋环流实验（World Ocean Circulation Experiment, WOCE）的组成部分，其核心目标是将通用环流模型（general circulation model, GCM）与多源观测数据相结合，以定量刻画随时间演变的全球海洋状态。本数据集包含原始ECCO1项目以及后续ECCO-GODAE（全球数据同化实验，Global Data Assimilation Experiment）和GECCO（德国ECCO）产出的数据产品。
数据集共包含四类数据：
1) 月尺度、10天尺度、日尺度或12小时尺度的海洋模型状态、调整后的强迫场与混合系数；
2) 进入优化流程的观测数据集；
3) 由模型代价/目标函数计算得到的模型输出与可用观测之间的失配量；
4) 已公开发表的过往估算结果

背景概述

该数据集是ECCO（估算海洋环流与气候）联盟的数据产品集合，旨在结合环流模型和观测数据，生成全球海洋状态的定量时间演化描述。数据集包含多个项目（如ECCO1、ECCO-GODAE和GECCO）的成果，涵盖不同时间分辨率的模型状态、观测数据、模型误差以及历史估计，时间跨度为1951年至2011年，空间覆盖全球海洋范围。
