- 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
- (*8) S2S providers have already officialy agreed with changing the current licence to CC BY 4.0 or CC BY NC 4.0 The current S2S licence will be updated accordingly in near future after the migration of data access to the new ECMWF datastore (ECDS)
