Feature	Contributor(s)	Model scope	Notes
Updates that will affect full-chemistry simulations
CEDS v2 emissions through 2019	Patrick Campbell (NOAA-ARL) Melissa Sulprizio (GCST)	Emissions	See geoschem/geos-chem #757

Overview
Below we summarize the notable changes caused by specific updates. Supplementary plots may be viewed at http://ftp.as.harvard.edu/gcgrid/geos-chem/validation/InternalBenchmarks/. 1. CEDS v2 emissions through 2019 This update changes the default global anthropogenic emissions inventory from the CEDS GBD-MAPS emissions (McDuffie et al., 2020) to CEDS v_2021_04_21. A comparison of 1-year HEMCO standalone simulations with two CEDS inventories (all other emissions off) may be found at http://ftp.as.harvard.edu/gcgrid/geos-chem/validation/CEDS_comparison/.

Improved wet scavenging from Luo et al. (2020) (as option) Some small differences at the level of numerical noise (i.e. differences ~1e-6X or ~1e-7X smaller than values) still occur even when the default wetdep scheme is used. This is because we now better enforce `REAL8` precision by adding `_fp` or `_f8` suffixes to numerical constants where they were lacking in both Luo and default wetdep schemes. Additional 1-month benchmarks with the Luo et al. (2020) wet deposition scheme were also completed. Results of those benchmarks are linked above. 4. Blowing snow emissions of sea salt and sea salt bromide* Lyatt Jaegle wrote, "I have looked at the benchmaks and it looks good to me, with changes in SALA, SALC, BrSALA and BrSALC as expected. As this is a simulation for July, the largest changes are seen in the SH polar regions. With decreasing sea salt emissions from the oceans due to to cold temperature suppression and increased emissions over sea ice due to blowing snow sea salt emissions."

Add carbon to species scale factors to AEIC VOC emissions This update fixes an issue introduced in GEOS-Chem 13.0.0 when carbon-based units were removed from HEMCO and GEOS-Chem. AEIC emissions were never updated to include the proper carbon to species scale factors. This fix increases VOC species concentrations aloft.
