is this config file being used by mem000 in ensemble?, if so, then DO_CA should be YES.

GFS is using CA, so DO_CA should be YES.

@bingfu-NOAA @EricSinsky-NOAA Is there a time that we want to start the model with these files? i.e., use them in more ways than a RERUN?

For 00Z, we will stop at 16-day forecast, then warm start the model to run 16-48 days forecast segment. We will need those files at that time besides a RERUN.

Subsequent segments count as RERUNs inside the system.
