Multi-decadal initialized climate predictions using the EC-Earth3 global climate model Open
Initialized climate predictions are routinely carried out at many global institutions that predict the climate up to next ten years. In this study we present 30 year long initialized climate predictions and hindcasts consisting of 10 ensem…

The sensitivity of EC-Earth3 decadal predictions to the choice of volcanic forcing dataset: insights for the next major eruption Open
Large volcanic eruptions can have significant impacts on climate. Due to their unpredictable nature, when a major volcanic eruption occurs, decadal forecasts issued prior to the eruption will be inaccurate. Consequently, new decadal foreca…
