I have been running a control run using CCSM3 for 1800 years, and just recently had the simulation crash due to an error "TAIR band 7 11 34 -23.5461917239125533".
I found this error originated from the gaschem subroutine in sulchem.f90 of the atmospheric component. It appears to indicate that I'm getting an air temperature less than 0K at the grid point specified by (7,11,34). I discovered that the negative temperature did not originate in this subroutine, though. The negative temperature had been passed through four different subroutines before tripping the error message in gaschem. I traced it back all the way the beginning of tphysbc, but it appears to have originated outside this subroutine as well. When I set up a comment in physpkg, I was flooded by many negative temperature comments, even when I didn't encounter problems in the lower subroutines, so I haven't been able to trace this particular occurrence.
I would appreciate if anyone can tell me where and how the state temperature variables are defined, or especially if you have an idea what might be causing my simulation crash.
thank-you!
