General Overview

Data Assimilation For Fluid Dynamic Models

Project Specifications

During the spring semester of 2017, Dr. Spiller and myself have been working on the Data Assimilation of the Lorenz '63 system. The Lorenz '63 system is three-dimensional, nonlinear system that has chaotic solutions depending on the initial conditions and values of its parameters. I first worked to solve this system, using MatLab. From there I developed a Particle Filter and a Kalman Filter to see , from the calculated solutions, created 'noisy observations' by simply adding
