Data Access


Global Argo Data

Access to global Argo data is via two Global Data Access Centres (GDACs); one located in Monterey, USA (USGODAE) and the other in Brest, France (CORIOLIS).  Both GDACs hold the complete Argo data collection. Data can be selected using a latitude/longitude region and a time range or by Data Centre (DAC) or ocean region.  The data at the GDACs are in netcdf format with profile, trajectory, technical and meta files available for each float.

Global Argo data is available through two Global Data Access Centres (GDACs) in netcdf format.

Argo Documentation

Comprehensive documentation of the Argo data system is described in the data manuals; “A beginners’ guide to accessing Argo data” and "The Argo Data Management Handbook". The “Argo User’s Manual” and the “Argo Quality Control Manual” are invaluable guides for those working with Argo netcdf files who would like to understand the data formats and quality control methods applied to the data.   

These reference manuals are available from the Argo Data Management Website:
