SOCAT version 2020

Before using SOCAT data products, please read the Fair Data Use Statement

Data Access

SOCAT version 2020 data products are available in a variety of formats:

Interactive viewers

Use the Interactive Viewers from the Live Access Server to explore and download gridded or non-gridded data following selected criteria (region, year, platform, etc.). Making maps and property plots is straight forward and a good way to to get a quick overview of the data collection.

Synthesis and gridded files

Global and regional synthesis files, as well as gridded files, are available as text files and netcdf, respectively, via the OCADS Metadata Page at the National Centers for Environmental Information. Matlab code is available for reading these text files.

Recalculation

Recalculation in SOCAT version 2020 took place using Ferret scripts, based on Matlab codes by Are Olsen (University of Bergen/Bjerknes Centre for Climate Research). The Matlab codes can be obtained here.
