SUMMARY:MS6A - Technical Challenges and Opportunities for Digital Twins of
  the Earth System (Part 3/3)
DESCRIPTION:Minisymposium\n\nDigital Twins of Earth encapsulate both the l
 atest science and technology advances to provide near-real time informatio
 n on extremes and climate change adaptation in a wider digital environment
 , where users can interact, modify and ultimately create their own tailore
 d information. Recent work has demonstrated that global, coupled storm-res
 olving (or km-scale) simulations are feasible and can contribute to buildi
 ng such information systems. Advances in Earth system modelling, supercomp
 uting, and the ongoing adaptation of weather and climate codes for acceler
 ators are all crucial building blocks in enabling such endeavours. Going f
 rom high-resolution simulations to fully-featured Digital Twins requires n
 ew workflows and technical solutions to manage computational and data scal
 es and offer the envisaged user-experience. This multi-part minisymposium 
 aims to discuss the technical challenges of such endeavours, spanning from
  HPC adaptation and the use of new programming paradigms for effective uti
 lization of modern accelerator architectures, to data handling, visualizat
 ion and workflows.\n\nInformation Systems Technology for NASA Earth System
  Digital Twins\n\nThe term “Digital Twin” was first used in 2002 for produ
 ct lifecycle management. Since then, Digital Twin concepts have been propo
 sed in various domains until very recently for Earth Science. For NASA’s A
 dvanced Information Systems Technology (AIST) Program, an <em>Earth System

  of the ICON Model to Exploit Emerging Technology: An Overview\n\nThe Icos
 ahedral Non-hydrostatic (ICON) model has been developed jointly in the las
 t 20 years by the Max Planck Institute for Meteorology and the German Weat

 lization: A Fascinating Challenge\n\nThe development of AR/VR software for
  digital twin visualization presents an exciting challenge for software de
 velopers and designers to create engaging immersive and useful experiences
  for users. Digital twin is an evolving concept, but some directions are a
