Global Atmospheric System Studies Panel

The Global Atmospheric System Studies (GASS) Panel activities facilitate and support the international community that carries out and uses observations, process studies, and numerical model experiments with the goal of advancing the understanding and prediction of weather and climate. Primarily, GASS coordinates scientific projects that bring together experts to contribute to the physical understanding of atmospheric processes and their representation in weather and climate models.

The overarching questions that are addressed in the various GASS projects are:

  1. How do the micro to mesoscale atmospheric processes control global water and energy exchanges? (radiation budget, hydrological cycle, atmospheric circulations)
  2. What controls cloud phase and precipitation?
  3. What controls mesoscale organization?
