Chemistry-Climate Studies Using General Circulation Models

We propose a collaborative effort of research into the relationship between the chemistry of the atmosphere and climate.  We will combine the GCM expertise of the Goddard Modeling and Assimilation Office with the chemistry expertise of Goddard’s Atmospheric Chemistry and Dynamics Branch to develop a chemistry-climate model.  Specific scientific goals of this proposal are the role of dynamics coupling in stratospheric ozone recovery, the role of stratospheric and tropsopheric ozone in climate change, and the combined role of atmospheric chemistry and aerosols in climate change.  Some major features of the proposal include:  - Scientific issue driven model development - Step-by-step development and testing of coupled chemistry/climate model - Extensive comparisons to satellite and ground-based data - Collaborative efforts between Goddard and outside modeling and analysis groups - Traceability of ozone assessments back to 2002 WMO/UNEP assessment - Parallel development of gravity wave and convective parameterizations - Link with interactive aerosol development to form chemistry/aerosol/climate model - Availability of model output to scientific community
