    • Years of record

    • to

    The sea surface height relative to the geoid (the mean ocean surface of the Earth if the ocean is at rest) is derived from TOPEX/Poseidon, Envisat, Jason-1, and OSTM/Jason-2 altimetry measurements. Altimetry is a technique for measuring height. Satellite altimetry measures the time taken by a radar pulse to travel from the satellite antenna to the surface and back to the…

    The global mean sea level timeseries is an excellent, integrative indicator of climate change, providing a record independent of common metrics like global surface air temperature.  The major contributions to the observed sea level trend of 3.3 mm/year include the ocean's thermal expansion, meltwater from mountain glaciers, and discharge from the Greenland and…

    Using updated data from the World Ocean Database (Boyer et al, 2009) and improved ARGO profiling data, new estimates of ocean heat content and thermospheric sea level change (0-2000m) for the period 1955-2010 are derived.

    The Institute of Atmospheric Physics (IAP) ocean temperature analysis features global coverage of the oceans, at 1° x1° horizontal resolution on 41 vertical levels from 1-2000m, and monthly resolution from 1940 to present.  As such, it is aimed at studies of climate variability and change, from large regional to global scales, on timescales of months to decades.…

    ECMWF's current ocean reanalysis uses a sophisticated data assimilation methodology which includes a model bias correction. The ocean model used is forced by atmospheric daily surface fluxes, relaxed to SST and bias corrected. The Balmaseda et al (QJRMS 2013) reference provides excellent peer reviewed documentation and evaluation.

    The global sea level record from tide gauges is an important indicator of the evolution and impact of global climate change.  Tide gauge data also capture a variety of local and regional phenomena related to decadal climate variability, tides, storm surges, tsunamis, swells, and other coastal processes.  Tide gauge data are used to validate ocean models and to…
