By the end of 2020, the International Argo Program has collected more than 2.3 million temperature and salinity (TS) profiles over the global oceans. Although the Argo Data Assembly Centers (DACs) from various countries conduct a quality control to each TS profile, Argo dataset are becoming more and more complicated which brings difficulties when users read and make use of them. In order to facilitate the usage of Argo dataset, China Argo Real-time Data Center (CARDC) has started to reconstructed the TS dataset after a post-quality-control. The dataset is archived in .dat format, and consists of 2,244,712 data files with data size of 41.1 GB (compressed to 18 files with 7.56 GB). The analysis paper related to the dataset was published at IOP Conference Series: Earth and Environmental Science, 502, 2020.Browse
