EBI failure, HADV/ADV/HDIFF NaNs

Thanks. I didn’t end up needing to run in debug mode. Turns out the issue was in BCON. I’m using GEOS-Chem files for CMAQ BCON, and at some point in my preparation the very first timestep was left unassigned, so all variables were set to values on the order of e36.

Since you are also getting errors at 0:00, maybe you have a similar problem with missing BCON data being set to 1e36.
