Community models must be state-of-the-science, easy to use, well documented, extensively tested, widely available, and efficient on a broad spectrum of modern computational platforms. Ensuring these attributes are maintained in all CGD's community models is the responsibility of CGD's CESM Software Engineering Group (CSEG) and the CESM Software Engineering Working Group (SEWG).
CSEG's most important function is to provide modern Software Engineering support to all CGD sections and projects, as well as to all CESM Working Groups, including the Land Ice Working Group (LIWG), which otherwise has no direct NCAR involvement.
CSEG also runs the CESM test and port database for CESM Software developers to track and prioritize upcoming model changes, as well as to document associated problems.
