Space Science Breakout Group

1. Modeling nonequilibium phenomena / multiscale / phase transitions

Problem statement : Most systems in nature are far from equilibrium, whereas most theories are for equilibrium systems. Modeling geophysical / space systems is essential.

What can’t we do : Complete theory can not be developed in the near future as the theory of nonequilibrium thermodynamics is still developing.

Aproaches: Models based on data, information theoretic approach (data and theory)

Kinds of collaborations: Mathematics /Theoretical physics (e.g., renormalization group, statistical physics, ), simulations, signal processing, information theory, ..

2. Modeling with space - time data (non-compatible resolutions, sparse data)

Problem statement: Federation of data (Modeling with data from different sources with different resolutions) and modeling time evolution.

Approaches: Pixel integration, dimension reduction, source identification method, censoring and truncation, hetroscedastic measurement errors,

Collaborations: Statistics, parallel / grid computing,

3. Large scale simulations and data assimilation

Problem statement: Simulations using models (pde’s) and lattices, multiscale computing, 2-way nesting,

What we can’t do: Particle simulations with realistic parameters

Approaches: Pixel integration, dimension reduction, source identification method, censoring and truncation, hetroscedastic measurement errors,

Collaborations: computational science, data assimilation, numerical weather forecasting,
