Aerosol Properties, Processes & Influences on the Earth's Climate (APPRAISE)

Programme overview

The Aerosol Properties, Processes & Influences on the Earth's Climate (APPRAISE) programme examined the science of aerosols and their effects on climate.

Understanding atmospheric aerosols is important in helping us to improve models of likely climate change, particularly at regional scales.

Background & objectives

The APPRAISE programme's aim was to help us understand and quantify how aerosols:

  • affect the Earth's radiation budget, by scattering and/or absorbing radiation;
  • influence clouds, and hence indirectly affect climate and the hydrological cycle;
  • contribute to feedback processes between land, the biosphere and climate.

APPRAISE worked to develop climate models which better-represent these processes, making climate change predictions less uncertain.
