@mdietze, @Aariq should I turn to using logger.error in-place of logger.severe for the fix ?

[mdietze]

I think either error or severe is fine. We tend to lean towards error over severe in cases where there are multiple ensemble members and/or locations and only a subset might be failing (i.e. we don't want to kill other ensemble members over an error in just one).

If this fix eliminates the dependency on PEcAn.DB then the DESCRIPTION and make should also be updated
