Below we summarize the notable changes caused by specific updates.
Scale DICE-Africa emissions to address errors in inventory
- This update contributes to changes in BC and OC concentrations over and just downwind of Africa. Slight differences can also be seen over Africa in the emission maps. The impact on the inventory emission totals are included below.
###############################################################################
### Inventory totals for DICEAfrica ###
### Ref = GC_12.5.0; Dev = GC_12.6.0 ###

GCHP and GEOS-Chem Classic difference of differences
This table contains plots comparing the difference [GCHP 12.6.0 - GCHP 12.5.0] against the difference [GC Classic 12.6.0 - GC Classic 12.5.0], taken from 1-month benchmark simulations.
NOTE: At present, we have only created the diff-of-diffs plots for species concentration. This can be extended to other categories in the future.
