Climate-motivated studies of Earth's clouds and aerosols frequently focus on their impacts on radiative budgets, distinguishing them from weather- and health-motivated studies. Our chief objective, serving development of the ModelE general circulation model at GISS, is to advance the fidelity of ModelE's representation of stratiform and convective cloud systems by advancing understanding of biases relative to observations and improving parameterization of cloud physics to reduce them. At the core of many of our studies are three-dimensional cloud simulations that resolve cloud-scale motions, where the details of cloud microphysics and its coupling with dynamics and aerosols may be relatively well resolved and compared with fine-scale observations. We maintain and extend the single-column model version of ModelE to allow apples-to-apples comparisons with large-eddy simulations. Our studies generally focus on the intersection of model simulations with observations, including airborne-, satellite- and ground-based remote sensing and in situ measurements. We use measurements to evaluate and improve models; we also use models to integrate and understand observations and to better characterize remote-sensing retrievals. In support of ModelE development, we study all cloud types relevant to climate, ranging from marine and continental shallow, warm clouds. through mixed-phase stratiform and convective clouds, and convective and synoptic cirrus ice clouds. We also invite applicants who are interested to study energy and water cycles, tropical rainfall, or other more specific topics where climate model cloud and convection parameterization plays an important role.
