Interdisciplinary aspects: SOC occurs in many different physical systems ! What properties of SOC are common in all physical systems? Are there statistical aspects that are universal in all systems? Are there universal parameters (fractal dimensions, powerlaw slopes) ? Where does the physics play a role (scaling laws of physical parameters)? Can we come up with a SOC theory that includes both universal statistical aspects and the physical scaling laws of a particular system?

Goals identified in our ISSI proposal : Data analysis of statistical datasets of SOC phenomena, using new and comprehensive data sets: Can we expect new observational results at 2nd ISSI Team meeting in 2013?

Goals and problems identified in our ISSI proposal : Data analysis of statistical datasets of SOC phenomena, using new and comprehensive data sets (2) Improve diagnostics of powerlaw-like distributions: How to identify scaling and universality in experimental and computational data? (Finite-size effects, variable drivers?) (3) How to identify and characterize between SOC and non-SOC mechanisms? (turbulence? network theory?) (4) What part of SOC phenomena is captured by lattice models and is there a route to basic theories and first-principle equations?

Metrics of Observables, Statistical Distributions and Physical Processes that need to be defined in order to discriminate SOC from non-SOC processes

Metrics of Physical Processes vs. Observational Properties Can we refine the metrics ?
