Air Quality

  • Global Air Quality Forcast

The GEOS-CF (composition forcasting) system, with global ~25-km resolution, combines:

  • The GEOS model/assimilation system (meteorology, transport, etc)

  • Aerosols from NASA’s 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.
