> Biography of Acting Director Lars Peter Riishojgaard
Lars Peter Riishojgaard
Lars Peter currently leads the Satellite Data Group in the
Global Modeling and Assimilation Office (GMAO) at the NASA
Goddard Space Flight Center, with his primary interests being
data assimilation methodology, societal impact of weather and
weather prediction, and the role of observational data and
satellite systems in remote sensing.
Lars Peter Riishojgaard received an M.Sc.
in geophysics from the University of Copenhagen in 1989 and a
Ph.D. in geophysics in 1992. 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 Meteorologiques
in Toulouse. Lars Peter served as a visiting scientist there from
1993-1994, a period during which 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 NASA Goddard as a Universities
Space Research Association visiting fellow. Lars Peter 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 accepted
a staff position at EUMETSAT in Darmstadt with user requirements
for future space-based observing systems as his main responsibility.
In August 2000, Lars Peter returned to the DAO to lead the
development of its analysis system, and has been a scientist in
its successor organization, the GMAO, since 2003. He has also
served as the NASA Deputy Director of the JCSDA since 2002. In
addition, in 2004, Lars Peter launched an initiative for a new
space mission, the Molniya Orbit Imager, whose purpose is to
demonstrate the high temporal resolution imaging capabilities
of this orbit for the high-latitude regions.
