1-month internal benchmarks
Each update that will introduce a significant change in the full-chemistry simulation is tagged with an alpha version in Git. For each of these alpha versions, the GCST runs an internal 1-month benchmark simulation to isolate the impact from that update.
For more details on the update(s) included in each alpha version and a link to benchmark results, see this Google sheet.

Overview | |||
Below we summarize the notable changes caused by specific updates. See also the internal benchmark results which isolate impacts from specific updates.
1. Update reactions with new JPL & IUPAC recommendations Kelvin Bates wrote, "Changes to most species' concentrations are minor, but all are well-documented in the forthcoming paper. Among the largest changes are (a) faster propane oxidation resulting in lower propane mixing ratios; (b) new propane branching ratios causing higher acetone production and mixing ratios; (c) lower C1 Criegee Intermediate + H2O reaction rate causing lower HMHP production; (d) lower Peracetic acid (MAP) + OH rate causing higher MAP mixing ratios and correspondingly lower mixing ratios of PAN and acetic acid; (e) slight increases in NOx, HO2, OH, H2O2 (all <2% in the troposphere) and decreases in surface ozone (-4%) and CO (<1%) due to a whole host of competing effects from changed reaction rates." Global mean OH changed by 0.15%. 2. Interim fix for runaway HMS chemistry Differences are very small (<<1%) for most species except for HMS which increases by 3%. Global mean OH changed by 0.006%. 3. Cloud-J for computing photolysis rates as default Changes are relatively small (<3%) for all species as expected from the change from Fast-JX to Cloud-J. Global mean OH changes by 0.38%. 4. Fix bugs setting strat aerosol OD passed to Fast-JX Changes are small as expected due to J-value changes. Global mean OH changed by -0.0018%. Lizzie Lundgren wrote, "Differences in stratosphere are clustered towards poles which is consistent with the new inclusion of polar strat cloud contribution for computation of J-values." 5. Bug fix for dry deposition to snow and ice Changes are small and are mainly restricted to the polar regions. Global mean OH changes by 0.0072%. 6. Bug fix for application of FRSNO in land cover arrays Changes are very small. Global mean OH changed by -0.00045%. Changes are on the level of numerical noise due to rebuilding the fullchem mechanism in KPP with new dummy species. Global mean OH changes by 0.0008%. 8. Add nitrate aerosol to Ox family definition in gckpp.kpp Differences are small (< 0.01%) for all species and global mean OH changes by 0.003%. These changes are introduced from rebuilding the fullchem mechanism in KPP. |
