Challenges and Opportunities of Seamless Earth System Modelling

Seamless Earth System (ES) modelling bridges spatial and temporal gaps. From an atmospheric perspective, this includes a full arc from past and recent weather and climate monitoring - towards future weather extremes in a changing climate under increasing greenhouse gases. To allow complex and comprehensive investigations of such weather-climate interplays, centrally including atmospheric composition, the modelling landscape had to change dramatically in the last few years. Here, I will review the current status of weather forecasting and climate modelling with the ICON modelling framework. In addition, I will explore relations with data driven methods and how models based on partial differential equations (here ICON) together with data driven models will help us to advance seamless ES modelling in the coming years - providing even better weather forecasts and climate projections to inform society.
