On 1 April 2021, the BOA_Argo dataset was updated to the end of 2020. The new dataset was produced with the global Argo TS profiles which had been post-quality-controled by CARDC. The dataset covers the periods of 2004-2020, including temperature, salinity, isothermal layer depth and mixed layer depth. Users are able to download them from ftp://data.argo.org.cn/pub/ARGO/BOA_Argo/.
