Multi-scale atmospheric dynamics
01 / The modeling system
A laboratory for the atmosphere.
gSAM provides a numerical framework for investigating atmospheric processes across a wide range of scales. It supports research into cloud systems, organized convection, and the interaction between small-scale physical processes and large-scale circulation.
Beyond idealized experiments, associated tools support the preparation of initial and boundary conditions for regional simulations and experimental forecasts.
