本文件的主要目的是介绍CryoSat海洋产品的现状，并概述所有相关的质量控制和验证活动。2010年发射的极地轨道欧洲航天局(ESA)的CryoSat任务主要是为了测量极地海冰厚度和冰盖海拔的变化。除了冰层监测目标之外，CryoSat还是海洋学界宝贵的数据来源。卫星的雷达高度计可以测量从开阔的海洋到海岸的高分辨率地球物理参数。为了能够充分进行科学和业务开发，海洋产品不断演变，需要通过基于多平台现场数据、模型和其他卫星飞行任务的面向科学的诊断进行质量控制和彻底验证。为支持欧空局，CryoSat海洋验证小组对近实时和离线海洋产品进行这项质量评估，评估范围既包括短期尺度(每日和每月监测)，也包括长期稳定性(年度趋势)。根据这些质量分析的结果和科学海洋界的反馈，欧空局打算在2017年秋季升级低温卫星海洋处理链。(C)2017年空间研委会。爱思唯尔有限公司出版。保留所有权利。
The main objectives of this paper are to present the status of the CryoSat ocean products and to give an overview of all associated quality control and validation activities. Launched in 2010, the polar-orbiting European Space Agency's (ESA) CryoSat mission was primarily developed to measure changes in the thickness of polar sea ice and elevation of the ice sheets. Going beyond its ice monitoring objective, CryoSat is also a valuable source of data for the oceanographic community. The satellite's radar altimeter can measure high-resolution geophysical parameters from the open ocean to the coast. To enable their full scientific and operational exploitation, the ocean products continuously evolve and need to be quality-controlled and thoroughly validated via science-oriented diagnostics based on multi-platform in situ data, models and other satellite missions. In support to ESA, the CryoSat ocean validation teams conduct this quality assessment for both the near real time and offline ocean products, both over short time scales (daily and monthly monitoring) and long-term stability (annual trends). Based on the outcomes from these quality analyses and feedback from scientific oceanographic community, ESA intends to upgrade the Cryo Sat Ocean processing chain for Autumn 2017. (C) 2017 COSPAR.
