Chuter-Aston-Skeldon-Roulstone paper on dynamical systems and data assimilation appears in Chaos

The paper “A dynamical systems analysis of the data assimilation linked ecosystem carbon (DALEC) models” has been accepted for publication in the journal Chaos, co-authored by the Surrey team consisting of Anna Chuter, Philip Aston, Anne Skeldon, and Ian Roulstone.  The paper considers the qualitative behaviour of one of the simplest carbon cycle models, the Data […]


Matt Turner’s paper on vorticity staircases appears in Physics of Fluids

Matt Turner‘s paper “Temporal evolution of vorticity staircases in randomly strained two-dimensional vortices” has been accepted for publication in Physics of Fluids.  In the paper, the evolution of a Gaussian vortex subject to a weak-external-random n-fold multipolar strain field is examined using fully nonlinear simulations. The simulations show that at large Reynolds numbers, fine scale steps form […]


Naratip Santitissadeekorn gives a talk at the University of Reading

Naratip Santitissadeekorn is visiting the Data Assimilation Research Centre (DARC) at the University of Reading today, to give a talk in the DARC Seminar Series on “Joint state-parameter data assimilation by a two-stage filtering technique“.  The talk is about an approach for a joint state-parameter estimation in a sequential data assimilation framework. The state augmentation technique, […]
