The data atmosphere model (DATM) is necessary when running standalone eCLM simulations, but not when eCLM is coupled with ICON. ICON supplies the upper boundary conditions to eCLM; thus running DATM alongside ICON doesn't make sense and just burns CPU cycles. This issue was initially raised by @s-poll.
@mvhulten extensively hacked on the src/datm code tree to see if the DATM streams file I/O could be completely disabled. Bypassing DATM proved to be more difficult than expected. Marco's debugging notes are logged here.
