Data Access<\/h3>\n

SOCAT version 4 data products are available in a variety of formats:<\/p>\n\n\n\n\n\n\n\n
\"\"<\/a><\/td>\n\n
Interactive viewers
\n<\/strong><\/h5>\n

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.<\/p>\n<\/td>\n
