Hello and welcome to the homepage of Professor Sue van den Heever's
research group. Our research focuses on cloud processes, specifically the microphysical and dynamical
characteristics of deep convective cloud systems, aerosol-cloud feedbacks, convective organization and
the representation of these processes in numerical models. More detailed information on the scientific
questions we are currently addressing can be found on our
research webpage and from our publications
publications. We use numerical models
to achieve our scientific goals, in particular the open source
Regional Atmospheric Modeling System (RAMS)
that is now developed and maintained by the van den Heever research group. We also utilize
satellite and radar data to conduct our research, and numerous members of our research group
have participated in a number of field campaigns. Our group, together with students from the Schumacher, Schubert, Rasmussen and Rutledge groups, recently completed C3LOUD-Ex, a field campaign to investigate updraft and cold pool
characteristics of convective storms over NE Colorado. The field campaign utilized drones, radiosondes and radar data from the CSU-CHILL facility to address the campaign science goals and was recently described in the Colorado State University Magazine and on SOURCE.
