Argo Real-time data

Since 2002, over 500 floats have been deployed by China Argo Project in the Northwestern Pacific Ocean, Indian Ocean, Southern Ocean and the South China Sea. These floats were deployed by about 21 PIs from 11 organizations. When floats were deployed, shipboard CTD and laboratory Salinometer (Guild Line AutoSal 8400B) were used to make synchronous observations of T/S. And water samples are taken and measured in order to get the accurate salinity value near the Argo floats deployed, for the purpose of understanding the CTD's performance and correcting the in-situ data provided by the Argo floats.

China Argo Real-time Data Center (CARDC)/CSIO routinely receives Argos, Iridium BDS and RUDICS messages every day, and carries out message decoding and real-time quality control (RTQC) according to the Argo RTQC manual. Then all the data are submitted into GDACs and inserted into GTS via China Meteorological Administration (CMA).

In October 2015, CARDC established a service for Chinese profiling float with Beidou satellite system.

From 2020,  CARDC's local host started to synchronize twice a day with the Coriolis GDAC server.
