- Table shows the centres providing data to this project together with the latest configuration of their systems.
- Follow the links in the first column for specific model description.
- S2S model outputs are stored in MARS on the common 1.5/1.5 regular lat-lon grid as per the data format specification here.
- the only exception is BoM (ammc) which has coarser resolution and is stored on its original model grid
- additional ocean parameters are stored on the 1.0/1.0 regular lat-lon grid

Remarks
- (*1) CNR-ISAC reforecasts are produced always starting from 1 January each reforecast year and then in 5 days intervals but always on the same days each month. For exact list of reforecast days refer to https://apps.ecmwf.int/datasets/data/s2s-reforecasts-daily-averaged-isac/levtype=sfc/type=cf/
- (*2) For exact list of CNRM reforecast dates refer to https://apps.ecmwf.int/datasets/data/s2s-reforecasts-instantaneous-accum-lfpw/levtype=sfc/type=cf/
- (*3) For exact list of JMA reforecast dates for each model version date refer to https://apps.ecmwf.int/datasets/data/s2s-reforecasts-instantaneous-accum-rjtd/levtype=sfc/type=cf/
- (*4) Lagged JMA ensemble created from 4 runs as described in JMA Model#GEPS1701
- (*5) Lagged JMA ensemble created from 2 runs as described in JMA Model#GEPS2003
- (*6) 0.5° and in the meridional direction, 0.25° from 10°S to 10°N, progressively decreasing to 0.5° from 10° to 30°, and is fixed at 0.5° beyond 30° in both hemispheres
- (*7) +1 means that the model produce unperturbed control forecast. In S2S archive for consistency, there is always one ensemble member archived as of type=cf (number=0) even when the model does not have control forecast concept at all
