Session

12.09.2017     10:00–12:00

Title:
MS27
Ensemble-based data assimilation and optimization in geosciences • Part III
Type:
Subsurface models (cryoshpere, hydrosphere, lithosphere, pedoshpere)
Room:

In the past decade, ensemble-based data assimilation and optimization methods have received great attention from researchers in various disciplines of geosciences, given their reliable performance, reasonable computational costs, the simplicity in implementations and the ability to quantify the uncertainties of the estimates. This minisymposium will bring together researchers in the field to communicate and discuss their recent developments and applications of the ensemble-based data assimilation and optimization methods. We encourage presentations on new methodologies, ideas or perspectives, numerical algorithm implementations, and open problems and challenges in real world applications.
