SUMMARY:Information Systems Technology for NASA Earth System Digital Twins
DESCRIPTION:Minisymposium\n\nJacqueline Le Moigne (NASA)\n\nThe term “Digi
 tal Twin” was first used in 2002 for product lifecycle management. Since t
 hen, Digital Twin concepts have been proposed in various domains until ver
 y recently for Earth Science. For NASA’s Advanced Information Systems Tech
 nology (AIST) Program, an <em>Earth System Digital Twin</em> <em>(ESDT)</e
 m> is defined as composed of three components: A <em>Digital Replica</em>,
  i.e., an integrated picture of the past and current states of Earth syste
 ms <em>Forecasting capabilities</em>, providing an integrated picture of h
 ow Earth systems will evolve in the future from the current state <em>Impa
 ct Assessment</em> capabilities, providing an integrated picture of how Ea
 rth systems could evolve under different hypothetical what-if scenarios. D
 eveloping such a vision will require technologies related to: integrating 
 continuous observations from various disparate sources; developing framewo
 rks that builds on inter-connected models; improving the speed and accurac
 y of integrated prediction, analysis and visualization capabilities (e.g.,
  by using machine learning); and utilizing causality and uncertainty quant
 ification to improve our understanding of the evolution of Earth Science s
 ystems as a function of their interactions with other Earth and human syst
 ems. In addition, AIST is also investigating interoperability standards to
  federate multiple Digital Twins, as well as computational resources requi
 red by those systems.\n\nDomain: Climate, Weather and Earth Sciences\n\nSe
