SUMMARY:MS4A - Technical Challenges and Opportunities for Digital Twins of
  the Earth System (Part 1/3)
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\nOpportunities and Challenges for Digital Twins of th
 e Earth System\n\nThe talk describes ongoing efforts to create digital rep
 licas of the Earth as part of the European Commission's Destination Earth 
 programme. Global, so-called "k-scale" simulations are the basis of buildi
