Climate Processes in CMIP5: A look inside the development process for the atmospheric component of the next generation GFDL climate model
We will discuss the development process for the atmospheric component of this future climate model. Prototype atmospheric configurations are currently under active development. These configurations are rooted in CMIP5 GFDL models, but with increased resolution and updated physics. The target horizontal resolution is 0.5 deg, with an option for a lower resolution version of 1 deg for certain applications. We also target several level of complexity for the chemistry and physics. In particular, the model will be capable of running from “emissions” as well as from “concentrations”, in regard to both the carbon cycle and aerosols.
Clouds and convection have been an initial focus. We will describe metrics being utilized for evaluating prototype configurations. Results will be presented, highlighting areas where progress has been accomplished as well as areas where challenges remain. Opportunities for involvement by a wider community will also be discussed.
