Oceanic Heat Content, Mixed Layer Depth and Depths of 20°C and 26°C Isotherms

Product Families
Ocean Heat Content
Summary

Oceanic Heat Content (OHC) is the measure of the integrated vertical temperature from the sea surface to the depth of the 26°C isotherm and computed from the altimeter-derived isotherm depths in the upper ocean relative to 20°C.  Global 0.25 degree grids are generated daily for OHC, mixed layer depth and depths of 20°C and 26°C isotherms for 3 ocean basins:  North Atlantic, North Pacific and South Pacific 

Sea level Anomaly and Geostrophic Currents, multi-mission, global, optimal interpolation, gridded

Product Families
Ocean Currents
Sea Surface Height
Summary

The NOAA Laboratory for Satellite Altimetry's (LSA) sea surface height team produces 0.25-degree longitude/latitude Level-3 sea level anomaly (SLA) daily datasets by applying optimal interpolation to along-track satellite observations over the global ocean from a constellation of radar altimeter missions. Theses grids are produced with near-real time (3-5 hour latency) data.  Geostrophic Currents are produced from the SLA and are included in the dataset.
