Latest-generation atmospheric models carry the promise of addressing scientific issues that remain out of reach with current operational models. Putting them to work to answer scientific questions nevertheless requires significant effort and collaboration between experts of the numerics, computing, and scientific use of such models. HEAT sets up such a collaboration in order to address extreme atmospheric modelling applications and remaining numerical and computational challenges. Our specific objectives in terms of atmospheric sciences are to pioneer numerical modelling of the general atmospheric circulation of gaseous giant planets and to achieve milestones towards millenial-scale Earth system simulations relevant for palaeoclimatology. In terms of numerical and computational challenges, our objectives are to address the higher-order extension of highly scalable numerical methods for transport and dynamics, and bottlenecks for non-hydrostatic modelling, especially elliptic problems.
