Revision as of 18:16, 17 July 2019

This page includes information about all benchmark simulations for GEOS-Chem 12.4.0.

GEOS-Chem Classic 1-month benchmark

1-month benchmark plots

These benchmarks were primarily made with GCPy. Some benchmark plots created by GAMAP still remain because they have not been recreated in GCPy yet.

Comments on SURFACE differences:

Below we summarize the notable changes caused by specific updates.

Grid-independent dust emissions

  ###############################################################################
  ### Emissions totals                                                        ###

  ###############################################################################

  DST1 Natural              :      4.487948      11.225230       6.737282 Tg
  DST2 Natural              :      8.540177      23.995240      15.455063 Tg
  DST3 Natural              :     15.495716      43.538139      28.042424 Tg
  DST4 Natural              :     16.951628      47.628794      30.677167 Tg

Overall, dust emissions and concentrations increased with the introduction of the grid-independent emissions. The offline dust emissions have been scaled to match 2x2.5 online dust emissions for 2016, so further validation with a 1-year benchmark is needed to ensure these changes make sense.

Grid-independent lightning NOx emissions

  ###############################################################################
  ### Emissions totals                                                        ###
  ### Ref = GC_12.3.0; Dev = GC_12.4.0                                        ###
  ###############################################################################
                                   Ref            Dev            Dev - Ref
  NO Lightning              :      1.603119       1.700865       0.097746 Tg

Lightning emissions increased slightly when using the grid-independent lightning NOx emissions. The pattern of the changes globally is consistent with the expected changes from caused by regridding. Some differences in the vertical distribution of NOx can be attributed to these changing emissions, with slightly lower emissions aloft and slightly higher emissions in the free troposphere.

Grid-independent biogenic emissions

  ###############################################################################
  ### Emissions totals                                                        ###

  ###############################################################################
                                   Ref            Dev            Dev - Ref
  ACET Biogenic             :      3.199002       2.881931      -0.317071 Tg C
  ALD2 Biogenic             :      1.082313       0.877756      -0.204557 Tg C

  LIMO Biogenic             :      0.954841       1.022397       0.067556 Tg
  PRPE Biogenic             :      2.179011       1.971144      -0.207867 Tg C

  SOAS Biogenic             :      1.294232       0.086853      -1.207379 Tg

Biogenic emissions for all species except limonene decreased when using the grid-independent biogenic emissions. This caused decreases in many of the primary and secondary organic species over land.

Grid-independent sea salt emissions

  ###############################################################################
  ### Emissions totals                                                        ###
  ### Ref = GC_12.3.0; Dev = GC_12.4.0                                        ###
  ###############################################################################
                                   Ref            Dev            Dev - Ref
  SALA Natural              :      4.653316       5.620708       0.967392 Tg
  SALC Natural              :    281.640070     340.191067      58.550997 Tg

Sea salt emissions increased when using the grid-independent sea salt emissions, causing global increases in many of the sea-salt aerosol species (BrSALA, BrSALC, ISALA, ISALC, NITs, SALA, SALC, SO4s) at the surface and aloft.

Grid-independent soil NOx emissions

  ###############################################################################
  ### Emissions totals                                                        ###

  ###############################################################################
                                   Ref            Dev            Dev - Ref
  NO Soil                   :      1.365916       1.580800       0.214884 Tg

Soil NO emissions increased slightly when using the grid-independent soil NOx emissions. The pattern of the changes globally is consistent with the expected changes from caused by regridding.

Updated volcano emissions (1978-2019)

  ###############################################################################
  ### Emissions totals                                                        ###
  ### Ref = GC_12.3.0; Dev = GC_12.4.0                                        ###
  ###############################################################################
                                   Ref            Dev            Dev - Ref
  SO2 VolcDegas             :      1.553769       1.509524      -0.044245 Tg
  SO2 VolcErupt             :      0.000000       0.000000       0.000000 Tg

Updating to the newer volcano inventory reduced degassing volcano SO2 emissions by 0.044 Tg. This was expected because the last year of degassing emissions in the previous volcano dataset was 2009, which was a particularly active year. The eruptive volcano SO2 emissions remained at 0.

NOTE: The bug fix to rebuild chemical mechanisms for FAST-JX fix did not impact this benchmark. The bug was introduced in 12.3.2, and would not show up in the comparisons here between 12.3.0 and 12.4.0.

GEOS-Chem Classic 1-year benchmark

1-year benchmark plots

These benchmarks plots were made using a combination of routines from GCPy and GAMAP. The 6-panel concentration, difference, and fractional difference plots were created with GCPy, while the model vs observation plots, the emissions plots and tables, and the aerosol tables were created with GAMAP because they have not been converted to Python yet.
