Title: Advancing Atmospheric Predictions through the Data Assimilation of Measurements into Models
Abstract: Atmospheric conditions influence the operations, tactics and weaponry of the Air Force and her adversaries. It is thus crucial to improve atmospheric forecasts. In this seminar, I will present on improving atmospheric forecasts through the data assimilation (DA) of atmospheric observation and models. DA’s incredible flexibility to leverage a wide variety of observations will be illustrated using studies that assimilate satellite measurements of infrared radiances. I will then discuss a Navy-funded DA advancement that potentially improves both weather and aerosol forecasts, as well as ideas for potential collaborations between AFIT and my DA research group. No prior knowledge of DA or meteorology is needed to understand this seminar.
Bio: Dr Joseph Chan specializes in improving atmospheric forecasting through the data assimilation of observations into atmospheric models. To be precise, Joseph’s research focuses on (1) enhancing the usage of observations in atmospheric prediction models, and (2) developing novel efficient data assimilation algorithms to amplify the corrective power of observations in forecasting. Joseph is currently an Assistant Professor in the Department of Geography at the Ohio State University. Prior to that, Joseph earned his Honors’ in Physics from the National University of Singapore, and his PhD in Meteorology and Atmospheric Science from the Pennsylvania State University.
