New Paths in Integrated Earth System Modeling
New Paths in Integrated Earth System Modeling
Session ID#: 282444
Session Description:
The potential for enhanced Earth System Models (ESMs) has never been greater: increasing computational power, machine learning, greater sophistication in parameterizations, and new constraints from observational systems (e.g. PACE, SWOT, EarthCare, CERES, STRIVE). Legacy ESMs have made substantial advances in the skill of weather to seasonal predictions and climate representation as new observational constraints emerged, yet challenges remain to systematically incorporate all new observations in a timely and fully expansive manner and maximize the use of new computer hardware. This session solicits contributions from ESM developers on new directions that are being taken to maximize return on developer investments - including utilization of GPU technology, building seamless hierarchies from complex to simple configurations, developing unified model frameworks for multiple applications (e.g. ocean state estimation to initialized predictions to long-term climate simulations, data assimilation and model calibration etc.), emulator development and utilization, and new applications across existing models.
