  1. Particle filters for geophysical applications

    30 Apr 2015 | Presentations | Contributor(s): Javier Amezcua

    Avoiding degeneracy is a crucial challenge for particle filters. Results have shown that the number of particles scales exponentially with respect to the number of independent observations. In...

  2. Emulators in climate science. Uncertainty, sensitivity, calibration and more

    30 Apr 2015 | Presentations | Contributor(s): Peter Challenor

    An emulator or a surrogate is a statistical approximation of a complex numerical model. Emulators are fast to run and include a measure of their own uncertainty. This makes them suitable for a...

  3. Statistical Data Assimilation For Parameter Estimation In Costal Ocean Hydrodynamics Modeling

    30 Apr 2015 | Presentations | Contributor(s): Talea Mayo

    Coastal ocean models are used for a variety of applications, including modeling tides and hurricane storm surge. These models numerically solve the shallow water equations, which are derived by...

  4. Correlated Observation Errors in Data Assimilation

    30 Apr 2015 | Presentations | Contributor(s): Sarah Dance

    Remote sensing observations often have correlated errors, but the correlations are typically ignored in data assimilation for numerical weather prediction. The assumption of zero correlations is...
