Ocean temperature and saltiness from a model (ECCO snapshot)

ECCO Ocean Temperature and Salinity - Snapshot llc90 Grid (Version 4 Release 4)
ocean NASA POCLOUD Level 4 netCDF-4
In plain English

What it measures. Snapshots of ocean temperature and saltiness throughout the world's oceans at different depths, taken from a computer model rather than direct sensors.

How it's made. Produced by the ECCO project, which runs an ocean model and adjusts it to best fit a wide range of satellite and in-water observations, giving a physically consistent picture of the ocean.

How & where you'd use it. Used by oceanographers and climate researchers to study ocean circulation and how heat and salt move through the seas.

Official description

This dataset provides instantaneous ocean potential temperature and salinity on the native Lat-Lon-Cap 90 (LLC90) model grid from the ECCO Version 4 Release 4 (V4r4) ocean and sea-ice state estimate. Ocean and sea-ice state estimates from the 'Estimating the Circulation and Climate of the Ocean' are dynamically and kinematically-consistent reconstructions of the three-dimensional, time-evolving ocean, sea-ice, and surface atmospheric state, FLUX, and transports. ECCO V4r4 is a free-running solution of 1-degree global configuration of the MIT general circulation model (MITgcm) that has been fit to observations in a least-squares sense. V4r4 data constraints include sea surface height (SSH) from satellite altimeters [ERS-1/2, TOPEX/Poseidon, GFO, ENVISAT, Jason-1,2,3, CryoSat-2, and SARAL/AltiKa]; sea surface temperature (SST) from satellite radiometers [AVHRR], sea surface salinity (SSS) from the Aquarius satellite radiometer/scatterometer, ocean bottom pressure (OBP) from the GRACE satellite gravimeter; sea ice concentration from satellite radiometers [SSM/I and SSMIS], and in-situ ocean potential temperature and salinity measured with conductivity-temperature-depth (CTD) sensors and expendable bathythermographs (XBTs) from several programs [e.g., WOCE, GO-SHIP, Argo, and others] and platforms [e.g., research vessels, gliders, moorings, ice-tethered profilers, and instrumented pinnipeds]. V4r4 covers the period 1992-01-01T12:00:00 to 2018-01-01T00:00:00.
