The ENACT (Enhanced ocean data Assimilation and ClimaTe prediction) datasets are global ocean reanalysis datasets created by assimilating timely observational data into a numerical ocean circulation model (HOPE-E). ENACT was created as a part of the European Commission Framework 5 project motivated by the requirement to provide a detailed estimate of the ocean state at a particular time, providing gridded temperature, salinity, and velocity information. The CSIRO version of the ENACT dataset is a concatenation of the individual monthly variables Potential temperature, Seawater x-velocity & Seawater y-velocity into single netcdf files for the time period 1962-2004 with a spatial resolution of 1.0° x 1.0° at 33 depths. It has also been processed to include calculated anomaly, climatology, and seasonal forms of this data.

The ECMWF (European Center for Medium range Weather Forecasts) ERA-40 model uses a variational data assimilation system to make a new synthesis of the in-situ and remotely-sensed measurements made worldwide over the period since mid-1957. It produces the basic analysed conventional meteorological wind, temperature and humidity variables as well as stratospheric ozone, ocean-wave and soil conditions. The CSIRO archive contains monthly data for variables concatenated into a single contiguous netcdf file for the time period 1957-2002 with a spatial resolution of 2.5° x 2.5° and has also been further processed to include calculated Anomaly, Climatology and Seasonal forms of this dataset. Trend analysis data is available for specific variables.

The European Centers for Medium range Weather Forecasts (EMCW) Ocean Re-Analysis System 3(ORA-S3) datasets, created by the synthesis of surface and subsurface ocean observations (temperature, salinity, altimeter derived sea-level anomalies) , surface fluxes from atmospheric analysis and reanalysis, and a general circulation ocean model(HOPE). ORA-S3 was created and is used to provide initial conditions for coupled model forecasts as well as seasonal & decadal forecasting predictions within the ENSEMBLES project. The CSIRO version of the ORA-S3 dataset is a concatenation of the individual monthly variables into single netcdf files for the time period 1959-2006 at 256 lat & 195 Lon positions with 29 Levels. It has also been processed to include calculated Anomaly, Climatological and Seasonal forms of this data. There are 10 Monthly files 13.0GB, 10 Anomaly files 13.0GB, 10 Climatology files 557MB, and 10 Seasonal files 9.81GB.
