The Yuan-processed MODIS LAI product is used as input in the MEGAN extension (off by default) and in this version we have switched to the [http://ftp.as.harvard.edu/gcgrid/data/ExtData/HEMCO/OFFLINE_BIOVOC/v2019-10/README updated offline biogenic VOC files] generated with that MODIS LAI product.

|A second 1-month benchmark (Git tag [https://github.com/geoschem/geos-chem/releases/tag/12.7.0-rc.1 12.7.0-rc.1]) was performed to address the following issues identified in this benchmark:
 
*Bug fix in AODfromISOPSOA diagnostic to remove double use of BXHEIGHT
*In SfcFix/v2019-12/ directory, rename "GMI" to "WMO_2018" and remove unused "UCX" files
*Add WMO-2018 surface VMR for H2402

=== GCHP and GEOS-Chem Classic difference of differences ===
== 1-year Transport Tracers benchmarks ==


This table contains plots comparing the difference [GCHP 12.7.0 - GCHP 12.6.0] against the difference [GC Classic 12.7.0 - GC Classic 12.6.0], taken from 1-month benchmark simulations.
Two 1-year [[Transport_Working_Group#Transport_Tracers_simulation|'''Transport Tracers benchmark simulation''']] were performed using [[GEOS-Chem_12#12.7.0|GEOS-Chem 12.7.0]]:
*[http://ftp.as.harvard.edu/gcgrid/geos-chem/1yr_benchmarks/GC_12/12.7.0/TransportTracers/Run0-StdWetDep/ Run0-StdWetDep]
*[http://ftp.as.harvard.edu/gcgrid/geos-chem/1yr_benchmarks/GC_12/12.7.0/TransportTracers/Run1-LuoWetDep/ Run1-LuoWetDep]
Both simulations utilized 4&deg; x 5&deg; GEOS-FP met fields for the year 2016, with a '''10-year spinup'''.  These simulations can be used to validate the [https://www.geosci-model-dev.net/12/3439/2019/ Luo wet dep scheme] which is offered as an option starting in this version.

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.
NOTE: At present, we have only created the 6-panel difference plots for species concentrations and total emissions, but this can be expanded to other benchmark output in the future.

Global mean OH from log file (% change): 11.7991194063953 x 105 molec/cm3 (+0.33%)
Methyl chloroform lifetime (% change): 5.3039 years (-0.67%)
Methane lifetime (% change): 8.9168 years (-0.70%)
Overview
Comments on observed differences: Below we summarize the notable changes caused by specific updates.

Small alkyl nitrate chemistry

This update introduced four new advected species: MENO3, ETNO3, IPRNO3, and NPRNO3. These species have been added to the Nitrogen benchmark category. The global mean OH concentrations increase of +0.17% as a result of this chemistry update.


Methanol as part of standard chemical mechanism

With this update, methanol is now a chemically active species as well as a transported species. The overall impact of this update is small, contributing to a global mean OH change of +0.0083%.


Update to Yuan processed MODIS LAI product (covering years 2005-2016)

This update contributed to a global mean OH change of +0.21% and primarily impacts the biogenic emissions. The Yuan-processed MODIS LAI product is used as input in the MEGAN extension (off by default) and in this version we have switched to the updated offline biogenic VOC files generated with that MODIS LAI product. The impact on biogenic emissions is summarized below:

Latitudinally and monthly resolved fixed surface concentrations for long-lived organohalogen species (1750-2014) and methane (prior to 1979)

This update changes surface concentrations of CH3Br, CCl4, CFCs, CH3Cl, CH2Cl2, CH3CCl3, Halons, HCFCs, and as a result it also impacts concentrations of several other halogen species. Global mean OH changes by -0.12%.


Fix incorrect uptake coefficient for N2O5 in heterogeneous chemistry

This fix causes small changes in N2O5 and in some halogen species. The impact on global mean OH is -0.015%.


Fix offline dust scale factors

This update corrects the scale factor used for offline emissions of DST1 so that the species uses the same factor used for DST2, DST3, and DST4. The impact on emissions is summarized below:

Approval
Requires further investigation: A second 1-month benchmark (Git tag 12.7.0-rc.1) was performed to address the following issues identified in this benchmark:
  • Bug fix in AODfromISOPSOA diagnostic to remove double use of BXHEIGHT
  • In SfcFix/v2019-12/ directory, rename "GMI" to "WMO_2018" and remove unused "UCX" files
  • Add WMO-2018 surface VMR for H2402

1-year Transport Tracers benchmarks

Two 1-year Transport Tracers benchmark simulation were performed using GEOS-Chem 12.7.0:

Both simulations utilized 4° x 5° GEOS-FP met fields for the year 2016, with a 10-year spinup. These simulations can be used to validate the Luo wet dep scheme which is offered as an option starting in this version.
