Biography:

Dr. Lars Peter Riishojgaard received an M.S. in geophysics in 1989 and a Ph.D. in geophysics in 1992, both from the University of Copenhagen. His permanent affiliation from 1989 through 1995 was with the Research Department of the Danish Meteorological Institute in Copenhagen. Part of his thesis work (in general circulation modeling with special emphasis on processes relevant for stratospheric ozone) was carried out at the Centre National de Recherches M?t?orologiques in Toulouse. He took a visiting scientist position there from 1993-1994, during which time he pioneered the application of variational assimilation methods to the problem of driving dynamical flow fields from tracer observations. Late in 1995 he came to the Data Assimilation Office (DAO) at GSFC as a USRA visiting fellow. Dr. Riishojgaard designed and led the development of a three-dimensional ozone assimilation system, in parallel with carrying out research in the area of state-dependent covariance modeling. In June 1999 he took up a staff position at EUMETSAT in Darmstadt, with user requirements for future space-based observing systems as the main responsibility. In August 2000 he returned to the DAO to lead the development of its analysis system. Dr. Riishojgaard has been with GEST since September 2000.
