A Roadmap to the Implementation of 1km Earth System Model Ensembles (D1.2)

Joachim Biercamp, Peter Bauer, Peter Düben, Bryan Lawrence
2019 Zenodo  
The community of Earth system modelling has a strong interest to reach a horizontal resolution of about 1km for ensemble simulations with global coupled weather and climate models.  ...  However, we are still far from being able to run a 1 km coupled ensemble in an operational mode even if some of the fastest supercomputers that are currently available are used.  ...  This is a challenge for weather and climate modellers.  ...

The climate issue

2020 Nature Astronomy  
Quantitative estimates presented in this issue demonstrate that astronomers contribute more to climate change than the average global citizen.  ...  For some context, in a Comment Knud Jahnke and colleagues have performed a similar analysis for their home institute in Europe: the Max Planck Institute for Astronomy (MPIA) in Heidelberg.  ...  The average Australian astronomer generates at least 37 tCO 2 e per year, on top of personal emissions.  ...

Climate modeling

W.F. Spotz, P.N. Swarztrauber
2002 Computing in science & engineering (Print)  
We can simplify some of these models, depending on the question to be answered, but our climate system's complex interactions will continue to strain the limits of our largest supercomputers for the foreseeable  ...  To that end, climate models provide a relatively new and extremely valuable tool.  ...  Paul Swarztrauber is a senior scientist in the Scientific Computing Division at the National Center for Atmospheric Research and professor adjoint in the Computer Science Department at the University of  ...

Reversible logic for supercomputing

Erik P. DeBenedictis
2005 Proceedings of the 2nd conference on Computing frontiers - CF '05  
To further develop the idea of using reversible logic in supercomputing, a design for a 1 Zettaflops supercomputer as required for addressing global climate warming is presented.  ...  However, to create such a design requires deviations from the mainstream of both the software for climate simulation and research directions of reversible logic.  ...  I conclude a supercomputer based on reversible logic has some chance of addressing the example climate problem, but only if the direction of research into both reversible logic and climate modeling are  ...
