SOCAT Version 2

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

Data Access

SOCAT version 2 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.

Interactive Gridded Data Viewer
Synthesis and gridded files in text format

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

Recalculation

Recalculation in SOCAT V2 took place using Matlab codes by Are Olsen (University of Bergen/Bjerknes Centre for Climate Research). The Matlab codes can be obtained here.
