Global Air Quality Forcast
The GEOS-CF (composition forcasting) system, with global ~25-km resolution, combines:
The GEOS model/assimilation system (meteorology, transport, 鈥?
Aerosols from NASA鈥檚 GOCART module
Dynamic emissions modules (flow-dependent; observation constrained)
The GEOS-Chem chemical mechanism
Many (NASA) observations of physical and chemical parameters
Data are continuously downloaded from server and plotted and made a live video here.
