Argo’s more than 3500 floats provide 100,000 plus temperature and salinity profiles each year which create a large data set available on the Argo GDACs. As an alternative to using individual profiles from the GDACs, different groups around the world have produced various products based on Argo data. While these products include Argo data, they are not maintained by Argo itself. These products fall into the following categories:
- Gridded fields of temperature, salinity, mixed layer depth, etc.
- Velocity products
- Collections of profiles that have all been interpolated to the same pressure levels (standard depth level profiles)
- Collections of profiles that have been put through additional quality control measures
Below you will find links to the gridded products. Please click the other links above to access other Argo products or visit our operational center page to look at data from model outputs using Argo.
While each producer makes every effort to remove errors from their product, some might still exist. Therefore, users are reminded that these products are to be used cautiously. Please notify the producer if an error is discovered. Please credit the product appropriately.
If you have gridded fields or other products based on Argo data that you would like added to this page, please email firstname.lastname@example.org with all the necessary data for the table.
If using one of these products in a publication, please remember to acknowledge Argo data with the following statement and the Argo DOI.
These data were collected and made freely available by the International Argo Program and the national programs that contribute to it. (https://argo.ucsd.edu, https://www.ocean-ops.org). The Argo Program is part of the Global Ocean Observing System. “
