'''1. [https://github.com/geoschem/HEMCO/issues/46 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.

: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. [https://pubs.acs.org/doi/10.1021/acs.est.8b07241 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:

'''3. [https://github.com/geoschem/geos-chem/pull/689 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 [http://ftp.as.harvard.edu/gcgrid/geos-chem/validation/InternalBenchmarks/GCC_13.1.0-alpha.5/BenchmarkResults/ROy/ROy_FullColumn_ZonalMean.pdf full column] and [http://ftp.as.harvard.edu/gcgrid/geos-chem/validation/InternalBenchmarks/GCC_13.1.0-alpha.5/BenchmarkResults/ROy/ROy_Strat_ZonalMean.pdf stratosphere] from internal 1-month benchmark 13.1.0-alpha.5.


'''4. [https://github.com/geoschem/geos-chem/issues/685 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 [http://ftp.as.harvard.edu/gcgrid/geos-chem/validation/InternalBenchmarks/GCC_13.1.0-alpha.7/BenchmarkResults/Aerosols/PM25_single_level_comparison.pdf 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:'''
*[https://github.com/geoschem/geos-chem/pull/364 Initial modifications for HEMCO internal grid]
*[https://github.com/geoschem/geos-chem/pull/495 Add fixes and simplifications to calc_met_mod.F90]
*[https://github.com/geoschem/geos-chem/issues/598 Remove useless computations from reaction rate-law functions]
*[https://github.com/geoschem/geos-chem/pull/664 Fix typo in call to HetIxCycleSSA]
*[https://github.com/geoschem/geos-chem/issues/693 Fix parallelization issues in ISORRPOIA and get_ndep_mod.F90]

'''Additional notes:'''
*The issue of [https://github.com/geoschem/GCHP/issues/72 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 [https://github.com/geoschem/geos-chem/pull/663 updates to speed up the chemical solver].
