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/13.4.0/.
1. Migrating sulfate chemistry into KPP An error in GEOS-Chem 13.3.0 meant that HMS chemistry was not properly implemented. This has now been fixed in 13.4.0-rc.0 (see this plot). Furthermore, this update causes the global tropospheric mass of BrO to increase by 11%: before after diff % diff BrO trop mass [Gg] : 9.543837 10.623180 1.079344 11.309 This increase (see plot) seems to be caused by the sulfur reactions on sea salt that were added to the KPP-generated chemical mechanism. The area of greatest change of BrO is at the surface southern extratropics, an area of high sea salt emissions. We are investigating further. 2. Fix bug in Henry law CALC_HEFF routine in hetchem computations This update causes the global tropospheric mass of BrO to increase by 15%: before after diff % diff BrO trop mass [Gg} : 8.358857 9.663602 1.304745 15.609 Other changes in benchmark output related to this update are: 3. Fix scale factors applied to VOC aircraft emissions in AEIC inventory The updated scale factors, which correct the conversion from atoms C to kg species, result in significant decreases in emissions for VOC species. This occurs mostly in the northern hemisphere and up to the lower stratosphere (where most aircraft emissions are placed). ################################################################################### ### Emissions totals for inventory AEIC [Tg] ### ### Ref = GCC_13.3.0-rc.1; Dev = GCC_13.4.0-rc.0 ### ################################################################################### Ref Dev Dev - Ref % diff AEIC ACET : 0.000139 0.000086 -0.000053 -38.027 AEIC ALD2 : 0.001829 0.000996 -0.000833 -45.529 AEIC ALK4 : 0.005617 0.004274 -0.001343 -23.912 AEIC C2H6 : 0.000152 0.000122 -0.000031 -20.213 AEIC C3H8 : 0.000022 0.000018 -0.000004 -18.386 AEIC MACR : 0.001827 0.000100 -0.001727 -94.522 AEIC PRPE : 0.004855 0.003779 -0.001076 -22.168 AEIC RCHO : 0.001384 0.003358 0.001974 142.621 However, this update resulted in minimal changes to global quantities, as VOC aircraft emissions are typically less than 1Gg for the simulation month. 4. Bug fix: Remove double-counting of HCl uptake on acidic sea salt This update causes the global tropospheric mass of BrO to increase by 13%: before after diff % diff alpha.4 BrO : 7.354777 8.358857 1.004080 13.652 Other changes in benchmark output related to this update are: 5. Update surface resistance for ozone deposition to ice/snow Barten et.al 2021 (https://doi.org/10.5194/acp-21-10229-2021) increased the surface resistance of ozone dry deposition to snow and ice to 1E4 s m−1, this results in a reduction of ozone deposition velocity to ice of <= 0.01 cm s−1 (~ 66% reduction) which has better agreement with observations and results in improved comparison between Ozone observations in the arctic. This update was added in 13.3.3 but does cause very slight changes in NOx soil and fertilizer emissions, as shown below. The HEMCO soil NOx extension uses an manual diagnostic to keep track of NOx from fertilizers. ################################################################################### ### Emissions totals for species NO [Tg] ### ### Ref = GCC_13.3.0-rc.1; Dev = GCC_13.4.0-rc.0 ### ################################################################################### Ref Dev Dev - Ref % diff NO Aircraft : 0.156922 0.156922 0.000000 0.000 NO Anthro : 5.327773 5.327773 0.000000 0.000 NO BioBurn : 1.882279 1.882279 0.000000 0.000 NO Fert : 0.359627 0.359458 -0.000169 -0.047 NO Lightning : 1.664984 1.664984 0.000000 0.000 NO Ship : 0.073301 0.074878 0.001577 2.152 NO Soil : 1.745616 1.745500 -0.000115 -0.007 ----------------------------------------------------------------------------------- NO Total : 10.850869 10.852331 0.001462 0.013 7.
