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. Distribute CEDS emissions vertically in the boundary layer This update modified 2D CEDS energy and industry emissions and vertically distributes them based on scale factors provided by Barron Henderson. All species with CEDS emissions were impacted, including NO, CO, SOAP, SO2, SO4, pFe, NH3, BCPI, BCPO, OCPI, OCPO, MOH, EOH, C2H6, C3H8, ALK4, C2H4, PRPE, C2H2, BENZ, TOLU, XYLE, CH2O, ALD2, MEK, and HCOOH. Differences caused by this update are small, and can be seen as reduction of emissions and species concentrations at the surface primarily over land as well as increases aloft. ################################################################################### ### Emissions totals for inventory CEDS [Tg] ### ### Ref = GCC_13.1.0-alpha.7; Dev = GCC_13.1.0-alpha.8 ### ################################################################################### Ref Dev Dev - Ref % diff CEDS ALD2 : 0.154553 0.154553 -0.000000 -0.000 CEDS ALK4 : 6.199071 6.199253 0.000182 0.003 CEDS BCPI : 0.091399 0.091399 0.000000 0.001 CEDS BCPO : 0.365595 0.365597 0.000002 0.001 CEDS BENZ : 0.540499 0.540500 0.000001 0.000 CEDS C2H6 : 0.000000 0.000000 0.000000 nan CEDS C3H8 : 0.000000 0.000000 0.000000 nan CEDS CH2O : 0.188655 0.188656 0.000001 0.000 CEDS CO : 43.334313 43.334300 -0.000013 -0.000 CEDS EOH : 0.192327 0.192327 -0.000001 -0.000 CEDS HCOOH : 0.787155 0.787154 -0.000001 -0.000 CEDS MEK : 0.317764 0.317763 -0.000001 -0.000 CEDS MOH : 0.256436 0.256436 -0.000001 -0.000 CEDS NH3 : 4.532344 4.532343 -0.000001 -0.000 CEDS NO : 5.358063 5.358063 -0.000000 -0.000 CEDS OCPI : 0.517257 0.517259 0.000003 0.001 CEDS OCPO : 0.517257 0.517259 0.000003 0.001 CEDS PRPE : 0.278035 0.278035 0.000000 0.000 CEDS SO2 : 5.678095 5.678111 0.000017 0.000 CEDS SO4 : 0.176021 0.176021 0.000000 0.000 CEDS SOAP : 2.990060 2.990061 0.000001 0.000 CEDS TOLU : 0.694438 0.694440 0.000002 0.000 CEDS XYLE : 0.653520 0.653523 0.000003 0.000 CEDS pFe : 0.005678 0.005678 -0.000000 -0.000 NOTE: After the initial 1-month benchmark for this version (13.1.0-beta.0), the GCSC noticed large differences in NOx ship emissions. To avoid complications in the PARANOX ship plume model, which still computes 2D emissions, the advise from the GCSC was to not vertically distribute ship emissions. We reran the 1-month benchmark (now tagged 13.1.0-beta.1) restoring the 2D ship emissions. 2. Diurnal scale factors of power plants emissions in China This update impacted CEDS emissions for the energy sector for species NO, CO, SOAP, SO2, SO4, pFe, NH3, BCPI, BCPO, OCPI, OCPO, MOH, EOH, C2H6, C3H8, ALK4, C2H4, PRPE, C2H2, BENZ, TOLU, XYLE, CH2O, ALD2, MEK, and HCOOH. To apply this update, the default diurnal scale factors from EDGAR are removed before the diurnal scale factors from PKU are applied to CEDS emissions over China only. Differences were very small due to distributing emissions differently across the 24 hours, as summarized below: ################################################################################### ### Emissions totals for inventory CEDS [Tg] ### ### Ref = GCC_13.1.0-alpha.6; Dev = GCC_13.1.0-alpha.7 ### ################################################################################### Ref Dev Dev - Ref % diff CEDS ALD2 : 0.154553 0.154553 -0.000000 -0.000 CEDS ALK4 : 6.199071 6.199071 -0.000000 -0.000 CEDS BCPI : 0.091399 0.091399 0.000000 0.000 CEDS BCPO : 0.365595 0.365595 0.000000 0.000 CEDS BENZ : 0.540498 0.540499 0.000000 0.000 CEDS C2H6 : 0.000000 0.000000 0.000000 nan CEDS C3H8 : 0.000000 0.000000 0.000000 nan CEDS CH2O : 0.188655 0.188655 0.000000 0.000 CEDS CO : 43.334313 43.334313 -0.000000 -0.000 CEDS EOH : 0.192327 0.192327 -0.000000 -0.000 CEDS HCOOH : 0.787156 0.787155 -0.000000 -0.000 CEDS MEK : 0.317764 0.317764 -0.000000 -0.000 CEDS MOH : 0.256436 0.256436 -0.000000 -0.000 CEDS NH3 : 4.532344 4.532344 0.000000 0.000 CEDS NO : 5.357930 5.358063 0.000133 0.002 CEDS OCPI : 0.517257 0.517257 -0.000000 -0.000 CEDS OCPO : 0.517257 0.517257 -0.000000 -0.000 CEDS PRPE : 0.278035 0.278035 -0.000000 -0.000 CEDS SO2 : 5.677984 5.678095 0.000111 0.002 CEDS SO4 : 0.176018 0.176021 0.000003 0.002 CEDS SOAP : 2.990056 2.990060 0.000004 0.000 CEDS TOLU : 0.694438 0.694438 0.000000 0.000 CEDS XYLE : 0.653520 0.653520 0.000000 0.000 CEDS pFe : 0.005678 0.005678 0.000000 0.002 3. Fix H2O boundary conditions at tropopause This fix caused small differences in many species at all levels. The difference in H2O at the tropopause may be seen in the zonal mean difference plots for the full column and stratosphere from internal 1-month benchmark 13.1.0-alpha.5. 4. Update PM2.5 definition This update impacted the PM2.5 diagnostic, but did not cause differences to species concentrations. PM2.5 decreased overall, as shown in this difference plot for the PM2.5 diagnostic from the internal 1-month benchmark for 13.1.0-alpha.7. 5. The following updates introduced differences on the order of numerical noise: Initial modifications for HEMCO internal grid Add fixes and simplifications to calc_met_mod.F90 Remove useless computations from reaction rate-law functions Fix typo in call to HetIxCycleSSA Fix parallelization issues in ISORRPOIA and get_ndep_mod.F90 Additional notes: The issue of low MSA values discovered in GCHP 13.0.0 benchmarks has now been fixed by an an update to treat REAL as REAL*8 in KPP when using Intel compiler. This fix came in with the updates to speed up the chemical solver.

+:NOTE: After the initial 1-month benchmark for this version (13.1.0-beta.0), the GCSC noticed large differences in NOx ship emissions. To avoid complications in the PARANOX ship plume model, which still computes 2D emissions, the advise from the GCSC was to not vertically distribute ship emissions. We reran the 1-month benchmark (now tagged 13.1.0-beta.1) restoring the 2D ship emissions.
