Modeling and Data Assimilation




(307) 463-1724


Dr. Laura Slivinski has been with the NOAA Physical Sciences Laboratory since 2015. She is a co-lead scientist on version 3 of the 20th Century Reanalysis Project, an effort to estimate global weather fields and their uncertainties for the past 200 years. Her other interests include developing a rapidly-updated global data assimilation system, data assimilation methodologies for nonlinear problems, coupled data assimilation, and observation impact studies. Prior to working in PSL, Dr. Slivinski studied Lagrangian data assimilation, and developed a novel method for assimilating passive drifter observations into fluid flow models. She remains interested in investigating methods for accurately estimating the true state as well as its uncertainties.
