Main research areas include data assimilation and inverse problems
in atmospheric chemistry and meteorology with a focus on
four-dimensional variational techniques and novel non-Gaussian error
Target areas for chemistry assimilation
include the stratosphere (globally) and the troposphere (continental
domain) with both gas phase and aerosol phase chemistry.
Assimilated data include in situ and remote sensing data in the
realm of atmospheric chemistry.
Meteorological data assimilation
activities include assimilation of radar data for quantitative
precipitation forecasts with special attention to prevailing non-Gaussian
error characteristics, and soil data assimilation.
include the development of algorithms for targeted chemical observations,
and also data assimilation of both atmospheric dynamical and chemical
variables on planet Mars.
Previous activities include parallel
computing with dynamical load balancing and numerical solution of
atmospheric transport- diffusions- reaction equations, and dynamics of
stratospheric-tropospheric exchange processes.
