Update GOCART external data to use data from DCOM

[WalterKolczynski-NOAA]

What new functionality do you need?

Currently, external data used by GOCART is being staged using historical data and maintained by @bbakernoaa. However, to move to real-time operations, we will need to pick this data up from DCOM and any additional processing needs to be determined and added.

What are the requirements for the new functionality?

Need to be able to run real-time forecasts with data provided from operational sources.

Acceptance Criteria

Able to run both retrospective forecasts and real-time forecasts with aerosols.

Suggest a solution (optional)

There are a few stages to this:

• [ ] Make sure necessary data is available on DCOM from data ingest
• [ ] Restage the historical external data to mirror the structure of DCOM
• [ ] Update workflow to use the new structure, likely falling back to the (reorganized) historical data location when data is not available on DCOM
• [ ] Any new jobs and scripts to process data need to be added to workflow

(possibly more to-be-added)

First, GEFS-Aerosols still needs to pick up GBBEPx emissions in the DCOM that the data flow team transmits every day; second, because GEFS-Aerosols forecasts are extended from 5 to 35 days, GEFS-Aerosols needs GBBEPx climatology emissions to cover the extral days. Climatology GBBEPx emissions are pre-generated and will be located under the FIX; finally, a new task combining GBBEPx real-time emissions and GBBEPx climatology emissions should be added to the global workflow.

Thanks to @bbakernoaa and @NeilBarton-NOAA , much of the work needed has been completed.
