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. HMS chemistry (via sulfate_mod.F90) This update introduces new advected species hydroxymethanesulfonate (HMS) in GEOS-Chem. This new chemistry has a relatively small impact on other species' concentrations and on global mean OH. Complete results from a 1-month benchmark evaluating the impact of this chemistry update may be viewed at this link. 2. C2H2 and C2H4 chemistry This update introduces new advected species C2H2, C2H4, ETHN, and ETHP and adds one photolysis reaction. The new chemistry has a large (>10% impact) on GLYC, GLYX, H2O2, HCOOH, HMHP, MO2, MOH, MP, SOAGX (see this table). Global mean OH is reduced by -1.49%. Complete results from a 1-month benchmark evaluating the impact of this chemistry update may be viewed at this link. 3. Fixed typo in CloudHet This fix has a large impact on many halogen species and changed global mean OH by +6.65%. These large changes are to be expected because the function in which this bug occurs (`CloudHet`) is used in the rate computations of many heterogeneous reactions. See this Github issue for further discussion on the changes from this fix. 4. Revise gamma(N2O5) computation; cap A at 3.2e-8 Prior to this fix, `gamma(N2O5)` (i.e. reaction probability) was too high over the oceans. This update now prevents `gamma(N2O5)` from exceeding ~0.036, which is consistent with lab results. We observe a relatively small (<10%) impact on most species, but ClNO2 shows a large decrease. But as `gamma(N2O5)` decreases, the production of ClNO2 via the reaction `N2O5 + HCl = ClNO2 + HNO3` likewise decreases, so the results are to be expected. See this Github issue for further discussion on the changes from this update. 5. Updates to IONO2 hydrolysis from Wang et al. (2021) This update replaced several heterogeneous reactions that converted gas-phase species HOI, IONO, and IONO2 to aerosol species ISALA and ISALC with the single hydrolysis reaction `IONO2 + H2O = HOI + HNO3`. We observe a large (>10%) impact on IONO2 and HOI, but a relatively small impact on other species (see this table). Global mean OH changed by -0.11%. See the original pull request on Github for more details of this update and its impact on model output. 6. Aromatic VOC chemistry This update added new advected species AONITA, AROMP4, AROMP5, BALD, BENZP, BZCO3H, BZPAN, CSL, MCT, NPHEN, PHEN, along with ~45 gas-phase reactions, 1 heterogeneous reaction, and 4 photolysis reactions. The impact on other species is summarized in this table, and global mean OH changed by -0.36%. Complete results from a 1-month benchmark evaluating the impact of this chemistry update may be viewed at this link. 7. Updated aerosol dry deposition This feature brings aerosol dry deposition in line with Emerson et al 2020, and several aerosol parameters within the dry deposition module were updated accordingly. Global mean OH increased by 0.024%. Most gas-phase species show small changes in mass (except for Br2 and ClNO2, which decreased by more than 5%). On the other hand, aerosol species such as AERI, ASOA1-4, DST1-4, show large decreases. Also, the mass of MSA increased by 7.7%. See this Github feature request for more information about this update. Complete results from a 1-month benchmark evaluating the impact of this chemistry update may be viewed at this link. 8. Update volcano emissions to May 2020 and add climatology The volcano emissions inventory from GMAO has been updated from v20180523 to v202005. Plots for a 1-month benchmark evaluating the impact of this fix may be viewed at this link. The impact on SO2 emissions from volcanoes is: ################################################################################### ### Emissions totals for inventory VOLCANOdegas [Tg] ### ### Ref = GCC_13.3.0-alpha.7; Dev = GCC_13.3.0-alpha.8 ### ################################################################################### Ref Dev Dev - Ref % diff VOLCANOdegas SO2 : 1.953161 1.826465 -0.126697 -6.487 ################################################################################### ### Emissions totals for inventory VOLCANOerupt [Tg] ### ### Ref = GCC_13.3.0-alpha.7; Dev = GCC_13.3.0-alpha.8 ### ################################################################################### Ref Dev Dev - Ref % diff VOLCANOerupt SO2 : 0.000000 0.101063 0.101063 nan 9. Avoid double counting of acetone source from monoterpenes when using online MEGAN This update reduced ACET emissions in the MEGAN extension. Plots for a 1-month benchmark evaluating the impact of this fix may be viewed at this link. The impact on total ACET emissions from MEGAN is: ################################################################################### ### Emissions totals for inventory MEGAN [Tg] ### ### Ref = GCC_13.2.1; Dev = GCC_13.3.0-alpha.0 ### ################################################################################### Ref Dev Dev - Ref % diff MEGAN ACET : 4.967504 4.374804 -0.592700 -11.932 The following updates introduced differences on the order of numerical noise: Cleaning up heterogeneous chemistry reaction rate computations Fixed typos in ClNO2 hetchem reactions: HNO2 should be a product, not HNO3
