CORA, Coriolis Ocean Dataset for Reanalysis

the coriolis ocean dataset for reanalysis (hereafter "cora") product is a global dataset of in situ temperature and salinity measurements. the cora observations comes from many different sources collected by coriolis data centre in collaboration with the in situ thematic centre of the copernicus marine service (cmems instac). the observation integrated in the cora product have been acquired both by autonomous platforms (argo profilers, fixed moorings , gliders , drifters, sea mammals) , research or opportunity vessels (ctds, xbts, ferrybox). from the near real time cmems in situ thematic centre product validated on a daily and weekly basis for forecasting purposes, a scientifically validated product is created. it s a "reference product" updated on a yearly basis since 2007. this product has been controlled using an objective analysis (statistical tests) method and a visual quality control (qc). this qc procedure has been developed with the main objective to improve the quality of the dataset to the level required by the climate application and the physical ocean re-analysis activities. it provides t and s weekly gridded fields and individual profiles both on their original level with qc flags and interpolated level. the measured parameters, depending on the data source, are : temperature, salinity. the reference level of measurements is immersion (in meters) or pressure (in decibars). cora contains historical profiles extracted from the en.4 global t&s dataset, world ocean atlas, seadatanet, ices and other data aggregators .the last version of the cora product are also available freely from the copernicus web site : global ocean- cora- in-situ observations yearly delivery in delayed mode global ocean- delayed mode gridded cora- in-situ observations objective analysis in delayed mode

柯里奥利海洋再分析数据集（以下简称“CORA”）是一项全球性的现场温度和盐度测量数据集。CORA观测数据源自多个不同来源，由柯里奥利数据中心与哥白尼海洋服务（CMEMS）现场主题中心（INSTAC）合作收集。集成于CORA产品中的观测数据由自主平台（如Argo浮标、固定浮标、滑翔机、漂流器和海洋哺乳动物）、研究或机会船舶（如CTD、XBT、渡轮箱）获取。从近实时CMEMS现场主题中心产品中，经过每日和每周的验证，用于预测目的，创建了一个经过科学验证的产品。这是一个自2007年起每年更新的“参考产品”。该产品通过客观分析（统计检验）和视觉质量控制（QC）进行控制。该QC程序的开发旨在将数据集的质量提升至满足气候应用和物理海洋再分析活动所需的水平。它提供了每周的T和S网格场和个体剖面，包括原始级别的带QC标记的数据和插值级别。根据数据源的不同，测量的参数包括：温度、盐度。测量参考水平为沉浸（以米计）或压力（以分贝计）。CORA包含从EN.4全球T&S数据集、世界海洋大图、SEADATANET、ICES和其他数据聚合器中提取的历史剖面。CORA产品的最新版本也免费提供于哥白尼网站：
