The uncertainties about interactions between aerosols, clouds, precipitation and climate (ACPC) are a fundamental limitation to our ability to understand past climate change and to project future warming reliably. This hampers the efforts of societies to optimally mitigate climate change, in pursuit of the goal to limit global warming to less than 2°C above pre-industrial levels.
The ACPC initiative aims at a better scientific understanding of these interactions at a fundamental level. The goal is to identify, disentangle and quantify signals of impacts of aerosol perturbations on clouds, precipitation and radiation, taking into account adjustments and feedback processes, by synergistically exploiting observations and models across scales.
