I am studying data assimilation for numerical weather prediction. Specifically, I am researching localized particle filters and their utility for non-Gaussian and non-linear data assimilation problems. Additionally, I am researching the possibility of an hourly updated GFS. Previously, I have studied orographic precipitation, PM2.5 air pollution sensors, and clear sky satellite radiance measurements.
