ORAS5 global ocean reanalysis monthly time-series data from 1958 to present

This catalogue entry provides monthly mean time series from the global ocean and sea-ice reanalysis ORAS5 (Ocean Reanalysis System 5), with data organised to prioritise temporal access at grid point locations rather than full spatial fields. The dataset enables users to efficiently retrieve long, continuous time series for individual ocean points, supporting analyses of ocean variability and change without the need to download and process large global gridded datasets.

Pacific Ocean SST attribution experiment for winter 1997/98: PC98

4-month long 101-ensemble member seasonal attribution experiment (PC98) initialised on 01-November-1997 using the atmosphere-only version of SEAS5 (see Johnson et al., 2019) forced with daily ERA5 SST as in the reference experiment (R98) but with daily SST climatology over the tropical Pacific Ocean.
