The GEOS-Chem Support Team uses robust source code management techniques to facilitate the open-source development of GEOS-Chem, maintain code integrity, ensure proper documentation and traceability, and support users. Its principal activities are as follows:
Implementation of new GEOS-Chem developments into the standard model. Most developments of the model are initiated by individual users for their own scientific purposes. Their implementation into the standard model is led by the Support Team in collaboration with the developer. We use the Git software management system (Git, www.git-scm.com) to ensure that each user's source code revisions can be tracked properly.
Fundamental GEOS-Chem development. The Support Team conducts fundamental model development essential for the long term. This includes upgrades to new versions of GEOS meteorological data, acquisition and storage of data, implementation of new coding and data structures, and technical updates.
Benchmarking of new versions. The Support Team benchmarks each new version of GEOS-Chem following a standard protocol to ensure the traceability and integrity of the model.
Documentation, communication, and education. The Support Team maintains the GEOS-Chem User's Manual and wiki pages, publishes monthly e-newsletters, welcomes new users, offers programming guidelines and advice, develops standards for coding and documentation (GEOS-Chem Style Guide), instructs users on the use of various software tools, and conducts model clinics at Users' Meetings.
Development of supporting software. The Support Team publishes open-source software for the benefit of the GEOS-Chem and broader modeling community. It maintains GAMAP, a collection of IDL programs that facilitates the analysis and visualization of CTM data. GAMAP is the standard visualization tool for GEOS-Chem and is updated regularly to maintain compatibility with the standard model.
