Gridded fields and velocity products based on Argo data

Argo's more than 3000 floats provide 100,000 plus temperature and salinity profiles each year, but often it is necessary to combine the profiles into a grid to look at different water properties. Additionally, trajectories from Argo floats drifting at depth can be used to calculate velocities which may or may not be gridded to examine the currents at 1000 dbars. There are now several gridded fields and velocity products available on the world wide web based on Argo data, as well as other data sources. Below you will find links to these gridded fields and products.

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 temperature, salinity or velocity fields or velocity products based on Argo data that you would like added to this page, please email argo@ucsd.eduwith all the necessary data for the table.

Other derived quantities may be found in addition to temperature and salinity on some of the links below. Please visit our operational center page to look at quantities from model outputs.
