Modigliani explained that Earth system digital twins Venkatramani Balaji, Schmidt Futures, the plenary require unprecedented simulation capabilities––for session's second speaker, presented a brief overview of example, ECMWF aspires to have a simulation on the the history of climate modeling, starting with a oneorder of 1–4 km at the global scale, which could enable dimensional model response to carbon dioxide doubling the modeling of small scales of sea ice transformation in 1967. This early work revealed that studying climate and the development of more accurate forecasts.

The spatial and temporal scales for digital twins is critical model enables the estimation of both the spatial pattern to determine the following: the phenomena that can of energy use for each building and the hourly temporal be represented in a model; the correct equation set for pattern (e.g., the commercial area uses the least energy at the fluid flow; the required physical parameterizations, midnight and the most at noon)
