Overview
The charge of the GEOS-Chem Steering Committee (GCSC) is to:
- Develop long-term strategies for the model and for the functioning of the user community
- Prioritize and enable model development in consultation with the GEOS-Chem Working Groups (WGs)
- Review model benchmarks and monitor the integrity and traceability of the model.
GEOS-Chem Steering Committee membership is rotating and international. Members are personally invested in GEOS-Chem through their research. See the Functioning of the GEOS-Chem Steering Committee document for details on:
- The role of the GEOS-Chem Steering Committee
- The structure of the GEOS-Chem Steering Committee
- The responsibilities of individual GEOS-Chem Steering Committee members
- The requirements to serve on the GEOS-Chem Steering Committee
- The process by which GEOS-Chem Steering Committee members are appointed
