Hello and welcome to the research group of Professor Sue van den Heever. 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. We utilize numerical models to achieve our scientific goals, in particular the open source Regional Atmospheric Modeling System (RAMS) that is developed and maintained by the van den Heever research group. We also draw on satellite and radar observations in 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. Several of our group also recently participated in NASA's CAMP2Ex held in the region of Philippines. More details about our CAMP2Ex activities were recently featured in SOURCE.
