Overview
Comments on observed differences: Below we summarize the notable changes caused by specific updates.

Isoprene chemistry

This update introduced several new advected species:
HMHP, ETP, HPETHNL, HCOOH, PYAC, ATOOH, ETHLN, MCRHN, MCRHNB, R4P, RP, RA3P, RB3P, PIP, PP, RIPA, RIPB, RIPC, RIPD, IEPOXA, IEPOXB, IEPOXD, ICHE, HC5A, HMML, HPALD1, HPALD2, HPALD3, HPALD4, IDC, IHN1, IHN2, IHN3, IHN4, INPB, INPD, IDN, ICN, ITCN, ITHN, ICPDH, IDCHP, IDHDP, IDHPE, MVKDH, MVKHC, MVKHCB, MVKHP, MVKPC, MCRDH, MCRENOL, MCRHP, MACR1OOH
and removed several species:
NPMN, ISOPND, ISOPNB, MOBA, MACRN, IMAE, SOAME, SOAMG, ISN1OG, ISN1OA, IPMN, HC187
The benchmark categories have been updated to account for these changes, following recommendations from Kelvin Bates.
For remarks on impacts caused by these changes, please see this discussion on Github.
NOTE: There are large decreases observed in AOD from isoprene SOA in this version. These changes are partially due to removing some species that were included in the isoprene SOA calculation in aerosol_mod.F, but are mainly due to the bug fix for the AOD from isoprene SOA diagnostic that went into GEOS-Chem 12.7.1.


Ozone deposition to the ocean

This update increases O3 concentrations over the ocean at the surface by up to 5 ppb, primarily at high latitudes. Global mean OH is increased by 0.15% with these changes.


Use online DustDead, MEGAN, SeaSalt, and SoilNOx emissions for benchmark simulations

The entries below from the emissions tables by species show differences caused by turning the DustDead, MEGAN, SeaSalt, and SoilNOx extensions back on in benchmark simulations. These changes are similar, but of the opposite sign, to the changes observed in the GEOS-Chem 12.4.0 benchmark when offline emissions were implemented.

1-year Transport Tracers benchmarks

Three 1-year Transport Tracers benchmark simulation were performed using GEOS-Chem 12.8.0:

  • GEOS-Chem Classic with the standard wet deposition scheme
  • GEOS-Chem Classic with the Luo et al. (2019) wet deposition scheme
  • GCHP with the standard wet deposition scheme

The GEOS-Chem Classic (w/ standard wetdep) simulation was spun up for 10 years, and the resulting restart file was used to initialize all three 1-year transport tracer benchmarks listed above.

Both GEOS-Chem Classic simulations utilized 4° x 5° GEOS-FP met fields for the year 2016. These simulations can be used to validate the Luo wet dep scheme which is offered as an option starting in this version.

The GCHP simulation used 0.25° x 0.3125° global GEOS-FP met fields for 2016 and ran at c48 resolution.

For comparison of the Pb-210 and Be-7 budgets to previous versions, please see the following posts on the Rn-Pb-Be simulation wiki page:
