DescriptionEarth system models are valuable tools for furthering
our understanding of past, present, and future climate
states. Because these models tend to be large and
complex as well as in a state of near constant
development, quality assurance (and subsequent
debugging) are critical pieces in the development cycle.
Here, we describe our multi-year effort to better
evaluate the quality and "correctness" of the Community
Earth System Model (CESM), a widely-used climate model.
Our approach depends on an initial coarse-grain
ensemble-based consistency test to determine code
correctness, which has already proved successful in
practice. The additional capability desired is a means
of easily tracing a coarse-grain failure to its root
cause, and we discuss our strategy and promising efforts
to date toward that goal.
