Add EDGAR BCPI and BCPO emissions for remaining sectors to DICE-Africa

This update was included in GEOS-Chem 12.6.0, which was released on 18 Oct 2019.

In GEOS-Chem 12.5.0, EDGAR v4.3.2 BCPI and BCPO emissions from the POW sector were added to the DICE_Africa section of HEMCO_Config.rc. The EDGAR BCPI and BCPO emissions should also be added for the remaining sectors to be consistent with OCPI and OCPI.

Scale DICE-Africa emissions to address errors in inventory

This fix was included in GEOS-Chem 12.5.0, which was released on 09 Sep 2019.

I’ve spotted a few bugs in the DICE-Africa inventory that I’d like to report. I plan to develop an updated DICE-Africa version 2 at some point that incorporates these updates, but I’d like to submit these fixes in the mean time. They include:
  1. Some emissions should be scaled to address errors in the inventory. These include all species from charcoal production and OCPI and OCPO from car emissions.
  2. EDGAR v4.3.2 BCPI and BCPO POW emissions missing in the DICE_Africa section of the HEMCO Configuration file.

Avoid double-counting between DICE-Africa and other inventories

This fix was included in GEOS-Chem 12.0.0.

Eloise Marais wrote:

DICE-Africa does not account for all anthropogenic pollution and there is overlap between what is in DICE and what is in EDGAR, so summing the two inventories would lead to double counting of pollution from vehicles and residential burning of traditional biofuels. I couldn’t think of a more eloquent way to sum together a selection of EDGAR emissions and all DICE emissions than to include relevant EDGAR emissions in the DICE-Africa brackets. I tried applying a reverse/ante regional map (0 for Africa; 1 everywhere else) to EDGAR emissions, but this doesn’t work and probably requires coding in HEMCO to accommodate this type of mask. This fix resolves all issues, and hopefully doesn’t introduce new issues. It didn’t when I implemented this in an earlier version of HEMCO with GEOS-Chem v10-01. I also ran a few tests with the HEMCO standalone file to confirm this. This approach also ensures stability when users use DICE for Africa and want to switch between different global emission inventories (e.g. HTAP or EDGAR).

Use unique names for DICE-Africa entries in HEMCO_Config.rc

This fix was included in GEOS-Chem 12.0.0.

In the original implementation of the DICE-Africa emissions in GEOS-Chem v11-02f, the same HEMCO container names were re-used for different emission sectors. For example, the name DICE_CO was found in multiple locations throughout the HEMCO_Config.rc file:

# ------------------------
#  Cars 
# ------------------------
0 DICE_CO    $ROOT/DICE_Africa/v2016-10/DICE-Africa-cars-2013-v01-4Oct2016.nc  CO  2013/1/1/0 C xy g/m2/yr  CO 26/1008 1 60
... etc. for other species ...

# ------------------------
#  Motorcycles 
# ------------------------
0 DICE_CO    $ROOT/DICE_Africa/v2016-10/DICE-Africa-motorcycles-2013-v01-4Oct2016.nc  CO  2013/1/1/0 C xy g/m2/yr  CO 26/1008 1 60
... etc. for other species ...

Reusing the same container name multiple times in HEMCO_Config.rc has no effect when running GEOS-Chem "Classic", but will cause GCHP to fail when reading data from disk. To avoid this situation, we have rewritten the HEMCO_Config.template files that ship with the GEOS-Chem Unit Tester to always use a unique container name for DICE-Africa entries. For example, we now have:

# ------------------------
#  Cars 
# ------------------------
0 DICE_CARS_CO    $ROOT/DICE_Africa/v2016-10/DICE-Africa-cars-2013-v01-4Oct2016.nc  CO  2013/1/1/0 C xy g/m2/yr  CO 26/1008 1 60
... etc. for other species ...

# ------------------------
#  Motorcycles 
# ------------------------
0 DICE_MOTORCYCLES_CO   $ROOT/DICE_Africa/v2016-10/DICE-Africa-motorcycles-2013-v01-4Oct2016.nc  CO  2013/1/1/0 C xy g/m2/yr  CO 26/1008 1 60
... etc. for other species ...

and so forth for the other emissions sectors.
