1. Allow per-species definition of KPP absolute and relative solver tolerances; Set absolute tolerances of dummy species to large value

Also includes hotfix from PR #2363, merged up. Differences are at the level of numerical noise.

2. Fix bugs in PDER, OCPISOA and TotalOC in complexSOA

Mean OH changed by +0.11%. Very small changes in NO Fert, ship, and soil emissions (maybe due to PARANOx). Complex_SOA shows small increases in most locations, particularly off the coast of South America, over the Arabian peninsula, and at polar latitudes... but ratios are between 0.99 and 1.01. Column AOD for SOA increases everywhere but especially in the Pacific between Mexico and Hawaii... Maximum change is 1.05X. Total column AOD shows slight decreases (to 0.99X)

3. Pass non-zero Ca2, Mg, and K cations to HETP #2398

Mean OH increases by 0.45%. No change in emissions. O3 conc at sfc increases by up to ~1ppb. OH increases slightly at surface, most pronounced in tropical regions, up to 1e-6 molec/cm3. NOx at surface follows the OH pattern. Column AOD for SO4 show small increases (< 10%) near the equator and decreases at about 40S. Column AOD from ISOA shows small decreases by up to 0.005X over continents. All other column AOD changes are zero or negligible. Halogen zonal mean plots show small changes in general. Cly at surface decreases up to 15% over oceans with small increases over continents. Bry at surface shows ~10% decreases at 30-40S, with up to 10% increases in the tropics (esp. the E Pacific).

4. Add fixes for ALK4 and R4N2 chemistry from Brewer et al. (2023, JGR)

Mean OH increases by 0.16%. No changes in emissions. O3 at surface increases everywhere, especially over continents, max increase ~2ppb over China/SE Asia.OH at surface increases by up to 2% over boreal forests, sub-Saharan Africa, the Amazon, and SE Asia. Surface NOx patterns follow the OH. Column AODs show either zero or negligible changes. Primary and secondary organics at surface show negligble changes as well. Zonal means show no significant changes.

5. Merge GEOS-Chem 14.4.3 back into the 14.5.0 development branch #2425

Benchmark is zero-diff w/r/t the previous alpha benchmark.

6. Chemistry for RCOOH, monoterpenes, new PNs and ANs from Travis et al. (2024) #2318 and Add emission factors for ALK6, C4H6, EBZ, STYR, TMB emissions in GFED and FINN biomass burning #285

"Mean OH decreases by 0.31%. Most species show significant changes in global mass, especially the VOCs. J-values of most species show very slight increases. Emissions are unchanged except for: HCOOH (which now has a contribution from biomass burning), the new species added in this PR, and ALK4 (which now has had some emissions attributed to ALK6 etc.). NO and NO2 emissions increase along the coasts, probably due to PARANOX. Several primary organic species (MOH, ISOP, LIMO, BENZ, TOLU, XYLE) show slight increases over the Amazon, sub-Saharan Africa, and boreal forests. MTPA shows decreases over oceans where concentrations are small. but also slight increases over the continents. ALK4 concentrations show large decreases over SE asia and Nigeria and smaller changes over places where concentrations are small. Most secondary organic concentrations show very small differences except for SOAGX, which increases everywhere. Others follow the pattern of ISOP. Also note: alpha.6 is 15% slower due to the additional advected species that have been added.

7. Fix inconsistent pressure units in HEMCO standalone #284

This PR only affects the HEMCO standalone model and does not change the benchmark results.

8. Fix mass non-conservation in VDIFF PBL mixing

Mean OH decreases by -0.029%. Most species show a change in global mass of less than +/- 1%. The largest changes are in the sea salt alkalinity species, SALAAL and SALCAL. SALAAL shows up to 40% enhancement over continents; SALCAL shows increases from 10-100% over continents. This is driven by the fix in PBL mixing. Several aerosol species (BrSALC, ISALC, NITs, SO4s) show significant increases in zonal mean plots at the tropopause and free troposphere, also driven by the mixing fix.

9. Restore dry deposition output in GCHP & GCClassic fullchem benchmark simulations #2144

This is a zero-diff update that causes the DryDep collection to be archived by default in all fullchem benchmark simulations.

10. Adding PPN photolysis #2371

Mean OH increases by 0.5%. Most species show small changes in global mass of less that +/- 0.5% except for A3O2, OTHRO2, and PPN. PPN decreases in mass by 68%, due to this update. Emissions are unchanged. Negligible changes for O3, CO, NOx, and OH at surface and 500hPa, as well as for column AOD's. Time spent in photolysis increased by 20% from alpha.7, but not sure if this is due to just the PPN itself.

11. Update run scripts and environment files for NASA discover cluster

This update does not affect benchmark simulations.

12. Update GFED4_Climatology entries for period 2010-2023 with new species

This update introduces a new GFED climatology that now includes emissions for the species that were added in the Travis et al 2024 chemistry. The GFED climatology is not used or benchmark simulations, so this update will not affect the results of benchmark simulations.

13. Update Cloud-J submodule to v8.0.0 and Support for Cloud-J v8.0.0

Mean OH decreases by 0.2% PPN J-value diagnostic shows zero everywhere (?!), maybe a diagnostic issue. All J-values show negligible differences. OH at surface increases by up to 1ppb, especially in the ITCZ where H2O absorption may be relevant. CO at surface increases up to 3ppb, especially in and off the coast of W. Africa, with small decreases over the SE US and Amazon. OH at surface changes negligibly, and NOx at surface increases by about 0.1ppb or less over continents, especially in SE Asia. Most primary organics show small changes in zonal mean plots, At surface TOLU, XYLE, TMB, and similar species increase by up to 1.5X, with the greatest increases in the tropics.

14. Store aerosol-specific optics files in new Aerosol_Optics data directory #2426

This update moves several configuration files containing aerosol optical properties. It does not change benchmark results.

15. Use JVN_ as max not exact number of J-values Cloud-J

This update restores PPN photolysis only. Mean OH increased by 0.04%. Emissions are unchanged except for very slight differences in NO and O3 caused by PARANOx. Most species show a global mass change of +/- 0.5 or less, many species have diffs much less than that.

16. Bug fix: Reorder photo rxns for PNs and ANs (from PR #2318)

This update places PNs and ANs species in the proper order for FJX_j2j.dat. It also restores photolysis for these species (thanks to the fix in Cloud-J PR #26), which in previous alphas was zero. Mean OH increases by 0.022%. But the ANs and PNs show no difference in J-values. I believe it may have been because the FJX_j2j.dat with the 177 photo species may not have been updated properly. Thus this alpha only seems to show the contribution from PPN photolysis, which is very slight.

18. Update Is_Photolysis tags in species_database.yml to be consistent with Cloud-J file FJX_j2j.dat

The only difference is that the J-value diagnostics now contain the new species added in the Travis et al 2024 chemistry.

19. Bug fix: ALK6 in HEMCO_Config.rc should be ALK7

This update increases ALK7 concentrations over land by fixing a bug where ALK7 emissions were not actually included. This has the result of increasing surface ozone slightly. Global mean OH changed by -0.18%.

20. Updated soil NOx scheme from Yi Wang et al. (2021) as an option #2430

This update does not change benchmark results, as this scheme is currently disabled. We need to obtain a sufficient archive of the TSOIL1 met field before we can activate the new soil NOx scheme.

21. Fix dry mass fraction of sea salt in aerosol thermodynamics #2467

NH4, HMS, and ISALA increase slightly over oceans, while NIT, SALAAL, SALACL, SALCAL, SALCCL, and SO4s decrease slightly. Global mean OH changed by -0.36%.

22. Remove J-value diagnostics which are all zero #2464

This update removes species from the JValues collection that do not have an entry in the FJX_j2j.dat configuration file that is used for Cloud-J. Benchmark results are not affected otherwise.

23. Restore stale workflow (PRs in GCClassic, GCHP, geos-chem, HEMCO repos)

This PR only affects the GitHub "stale" action, which marks issues and PRs as stale after a certain period of time with no activity.

24. CH4 reservoir seasonality

This update only affects CH4 and carbon specialty simulations.

25. Bug fix for double counting CH4 agricultural burning emissions

This update only affects CH4 and carbon specialty simulations.

26. Fix a bug in coarse-mode seasalt Ca, Mg, and K

Large (> 10%) changes seen in many aerosol species including BrSALA, BrSALC, SALACL, SALCAL, SALCCL, NITs, SO4s Global mean OH changes by 0.61%.

27. Clean up CHANGELOG.md for 14.5.0 release #2490

This update does not change benchmark results.

28. Update to Cloud-J 8.0.1 release

This fixes a bug that caused Cloud-J to potentially skip reading species from the FJX_j2j.dat configuration file. It does not change benchmark results.

29. Use ALK6 species name for >= C6 alkanes instead of ALK7

This update renames the ALK7 species to ALK6 to be consistent with the nomenclature in Travis et al 2024. It does not change benchmark results.

29. GCHP carbon simulation fixes

This update only affects the GCHP carbon simulation. It does not change benchmark results.
