GEOS-Chem 12.7.0

GEOS-Chem 12.7.0
03 Feb 2020

1. Small alkyl nitrate chemistry
2. Methanol as part of standard chemical mechanism
3. Update to Yuan processed MODIS LAI product (covering years 2005-2016)
4. Latitudinally and monthly resolved fixed surface concentrations for long-lived organohalogen species (1750-2014) and methane (prior to 1979)
5. Bug fix: Prevent differences in chemistry caused by toggling the ND65 bpch diagnostics off or on
6. Fix incorrect uptake coefficient for N2O5 in heterogeneous chemistry
7. Fix offline dust scale factors
8. Add GEOS-Chem "dry-run" option to obtain a list of required input files
9. HEMCO 2.2.0: Updates and fixes to improve file I/O
10. Implement Gan Luo et al wetdep (GMD-12-3439-2019) -- NOTE: THIS IS AN OPTION
11. CH4 soil absorption from MeMo model
12. Removal of most binary punch (aka "bpch") diagnostics
13. Add netCDF diagnostic for UV fluxes from FAST-JX
14. KPP equation reactivity rate and OH reactivity diagnostics
15. Bug fix for HEMCO standalone using high-resolution input grids
16. Incorrect units returned from GET_OH in sulfate_mod.F
17. Preserve mass conservation when advection is off by adding delta pressure to internal state for mixing ratio scaling during initialization
18. Use same CEDS anthropogenic emissions inventory as GC Classic, including 1750-1949 and additional VOC species
19. Assorted GCHP structural changes to facilitate GEOS-Chem in GEOS

• Move high-level GCHP files to GEOS-Chem repository
• Move GCHP run directory creation to GEOS-Chem repository

20. Use same precision in non-species Internal state variables and the equivalent GEOS-Chem states (REAL8)
21. Update ESMF to v8.0.0 public release
