Analysis and Quantification of Data Assimilation Based on Sequential Monte Carlo Methods for Wildfire Spread Simulation

Data assimilation is an important technique to improve simulation results by assimilating real time sensor data into a simulation model. A data assimilation framework based on Sequential Monte Carlo (SMC) methods for wildfire spread simulation has been developed in previous work. This paper provides systematic analysis and measurement to quantify the effectiveness and robustness of the developed data assimilation method. Measurement metrics are used to evaluate the robustness of SMC methods in data assimilation for wildfire spread simulation. Sensitivity analysis is carried out to examine the influences of important parameters to the data assimilation results. This work of analysis and quantification provides information to assess the effectiveness of the data assimilation method and 1 Authors’ addresses: Feng Gu, Department of Computer Science, 34 Peachtree Street, Suite 1450, Atlanta, GA 30303; Email: [email protected]; Xiaolin Hu, Department of Computer Science, 34 Peachtree Street, Suite 1450, Atlanta, GA 30303; Email: [email protected]. suggests guidelines to further improve the data assimilation method for wildfire spread simulation.
