CESM Models: CSIM5.0 Known Bugs


CSIM5.0 Known Bugs List

1. There is a bug in ice_mechred.F that was introduced with the vector code (reported June 15, 2004). Because of it, the ice strength is not being computed for points where there is net divergence. Since the vector code passed the climate equivalence test with the pre-vector code, our feeling is that the effect on the climate would not be significant, although this should be tested. [patch 1]

2. In versions of csim4_8_15 and earlier, there was a bug in the cona array in ice_history.F that caused some of the fields written to the history file to be multiplied by the wrong conversion factor.

Note: Bugs found in CSIM can be reported to the CSIM liaison.

CESM Project

The Community Earth System Model (CESM) is a fully-coupled, global climate model that provides state-of-the-art computer simulations of the Earth's past, present, and future climate states.

CESM is sponsored by the National Science Foundation (NSF) and the U.S. Department of Energy (DOE). Administration of the CESM is maintained by the Climate and Global Dynamics Laboratory (CGD) at the National Center for Atmospheric Research (NCAR).
