Lars Peter Riishojgaard

Lars Peter Riishojgaard received the M.S. and Ph.D. degrees from the University of Copenhagen, Copenhagen, Denmark, in 1989 and 1992, respectively. both degree in geophysics. Except for a year with EUMETSAT, Darmstadt, Germany (1999–2000), he has been with the Data Assimilation Office at the NASA Goddard Space Flight Center, Greenbelt, MD, since 1995, where he has studied the link between stratospheric dynamics and ozone variability, and he eventually designed and led the development of a three-dimensional ozone data assimilation system. In parallel with the ozone work, he carried out research in the area of state-dependent covariance modeling leading up to the design of a simplified implementation of a Kalman filter-like algorithm for a more general data assimilation system. Since August 2000, he has been leading the research and development work for the main DAO analysis system. His own research is now mainly focusing on the impact of existing and potential future satellite observations on assimilation and numerical weather prediction skill. He is also Deputy Director of the NASA/NOAA Joint Center for Satellite Data Assimilation.
