IS-GEO Telecon - "How Warm is it Getting?" and Other Tales in Uncertainty Quantification - Tuesday, October 3rd at 12pm PT

Allen Pope
Dear Cryolist,

While not strictly cryosphere, I thought this webinar (and community) would be of interest to many of those in the Cryosphere community. IS-GEO aims to support an emerging community of researchers in geosciences (GEO) and intelligent systems (IS). This research coordination network will enable advances in our understanding of Earth systems  through innovative applications of intelligent and information systems to fundamental geosciences problems.

"How Warm is it Getting?" and Other Tales in Uncertainty Quantification
(Juan M Restrepo)

In the statistics community  “Big Data” science is meant to suggest the combining of inferential and computational thinking.

We also speak of big data in the geosciences. However, the problems we pursue are often  extreme in the number of degrees of freedom,   and in many instances, non-stationary in its statistics. This usually  means that we are working with sparse observational data sets, even  if the number of observations is large. The Bayesian framework is  a natural inferential data assimilation  strategy in  geosciences,  to some extent because the degrees of freedom in the problem vastly  outnumber  observations but more critically, because the models we use  to represent nature have considerable predictive power.

Looking toward the future, we expect improvements in computational efficiency and finer resolutions in models, as well as improved  field measurements. This will force us to contend with  physics and statistics across scales and thus to think of ways to couple multiphysics and computational resolution,  as well as to  develop  efficient methods for adaptive statistics and statistical marginalization.

How this coupling is exploited to improve estimates that combine model outcomes and data will be described in tracking hurricanes and  improving the prediction of the time and place of coastal flooding due to ocean swells. Estimating the trend of Earth’s  temperature from sparse  multi-scale data will be used as an example of adaptivity in time series analysis.

Other open challenges in non-stationary big data problems will be described,  where progress could result from “Big Data Geoscience,” the tighter integration  of geoscience,  computation, and inference.
