This dataset contains parameters from 24-month extended-seasonal reforecasts using the ECMWF seasonal forecast system 5 (SEAS5, Johnson et al, 2019). The reforecasts are intialised on 01-May and 01-November with 25 ensemble members and cover the period 1981-2024. Note that these forecasts are not real-time operational products; rather, they are experimental and generated as part of the ASPECT project (https://www.aspect-project.eu). The ASPECT project has received funding from the European Union’s Horizon Europe – the Framework Programme for Research and Innovation (2021-2027) under grant agreement No. 101081460.
