An interactive, web-based tool to generate informative maps, animations, and plots that communicate and promote the discovery and analysis of the State Of The Oceans (SOTO). SOTO is a suite of tools presented through an interactive, web-based visualization front end. It provides access to a broad range of satellite-derived products and key parameters of interest to the oceanographic community. SOTO facilitates visual exploration and comparative analysis of physical oceanographic data, enabling your research.
The "+ ADD MORE" button can be used to activate sea surface salinity (SSS) data layers:
Characteristics of layers can be updated:
Live Access Server (LAS) is a web-based Level-3 (L3) data visualization and subsetting tool, designed to provide flexible access to geo-referenced scientific data. It enables users to: visualize data with on-the-fly graphics; request custom subsets of variables in a choice of file formats; access background reference material about the data (metadata); compare (difference) variables from distributed locations.
The "Data Set" button can be used to access the following datasets (SSS data are marked by asterisks, *):
NOTE: To see changes to updates to data sets, map type, date, etc., click the "Update Plot" button at upper left.
A tutorial for using LAS with Aquarius salinity datasets is provided on YouTube.
