|RADAR METEOROLOGY AND
research group is part of the University of Helsinki's atmospheric
science division. We study cloud and precipitation processes using a
instruments. Our main research instrument, Kumpula dual-polarization
weather radar is clearly visible on the roof of the department of
Physics building. In addition to it, we are using a variety of remote
sensing as well as in situ instruments, such as ground and aircraft
based particle imagers.
The group has extensive links to national and international partners,
such as Finnish Meteorological Institute and Colorado State University.
the main research topics of the group is characterization of high
latitude precipitation, that includes understanding of winter weather
precipitation processes and improvement in quantitative precipitation
estimation. The study extends from precipitation microphysics to
regional and global scales, by utilizing weather radars, NASA CloudSat
and upcoming NASA GPM and ESA EarthCARE satellites. Another major
research subject is improvement in warning process for such high impact
phenomena as hail, thunderstorms, heavy rainfall and urban floods. The
group is also involved in improvement of weather radar data processing
and radar signal processing algorithms, and development of new
operational radar applications.
Group members acquire a wide variety of skills, from carrying out filed
experiments to analysis of remote sensing data. This work requires
knowledge in a large range of subjects from cloud physics and physical
meteorology to electro-magnetics and signal processing.
