Sub-seasonal to seasonal prediction project (S2S)

The current focus of SNAP is analysing the stratospheric predictability and stratosphere-troposphere coupling present in the S2S hindcast dataset. More details of the dataset and how to use it can be found in the SPARC newsletter article about this phase of the proejct.

Data can be accessed through the ECMWF data portal either interactively or via the ECMWF python api. For questions about the data or help accessing it, please contact Andrew Charlton-Perez using the contact link below

Large amounts of hindcast data are available from the following models
