Workshop Overview:
Water vapor and cloud – climate feedbacks are currently considered to be the two most important feedbacks in the context of climate change. Although more realistic in terms of water vapor, present-day climate models fail to properly represent the physical processes associated with cloud-climate feedbacks. Remote sensing from space of these small-scale processes, such as clouds, turbulence and convection, is notoriously difficult and is still not good enough in order to provide the necessary constraints that would lead to a better understanding of the climate system and to improved climate prediction.
The goals of this Mini-Program are:
- To bring together scientists from different branches of the climate research community (theory, models, observations) to address key problems in the physics of climate feedbacks;
- To promote the use of remote sensing observational data in the climate physics and climate modeling community;
- To provide guidance on future research and future missions regarding the physics of climate change.
