• Radiative transfer in the atmosphere

  The representation of solar and infra-red radiation, and its interaction with clouds in our numerical models.

  Various radiative processes occur in the atmosphere: gases, aerosols, cloud droplets and ice crystals absorb radiation and emit thermal radiation. Aerosols, cloud particles and air molecules scatter radiation. The surface absorbs, reflects and emits radiation. The radiative properties
