Bio

Dr. Nikki Privé is an Associate Research Scientist at Morgan State University with GESTAR-II as a cooperative agreement employee with NASA Goddard Space Flight Center. She completed a B.S. in mechanical engineering at the University of Maryland, College Park, followed by an M.S. and Sc.D. in meteorology at MIT. Nikki has worked on Observing System Simulation Experiments (OSSEs) for numerical weather prediction (NWP) both with the NOAA Earth Science Research Laboratory and at the Globel Modeling and Assimilation Office (GMAO). Much of her research has focused on the roles of model and initial condition error in forecast skill, the calculation of observation impacts on numerical weather prediction, and the design of realistic OSSE frameworks. 

Presentation Title

Arctic OSSEs and Beyond

Presentation Abstract

Observing System Simulation Experiments (OSSEs) are a type of digital twin framework used to stimulate the potential impact of future observing networks on numerical weather prediction. This talk will give an overview of how data assimilation and OSSEs work, along with best practices for designing and conducting OSSEs. Available products and resources for building an OSSE framework will be described. Some challenges particular to developing OSSEs for polar regions will also be discussed.
