Effective Variational Data Assimilation in Air-Pollution Prediction by Rossella Arcucci, Christopher Pain, Yi-Ke Guo

“…To improve prediction for air flows and pollution transport, we propose a Variational Data Assimilation (VarDA) model which assimilates data from sensors into the open-source, finite-element, fluid dynamics model Fluidity. VarDA is based on the minimization of a function which estimates the discrepancy between numerical results and observations assuming that the two sources of information, forecast and observations, have errors that are adequately described by error covariance matrices. …”
