Global Tropospheric Aerosol Burdens

The table below lists the mean annual global tropospheric burden of several aerosol species in [Tg]. All values are obtained from 1-year benchmark simulations at 4° x 5° resolution.

NOTES:

  • The simulations that utilized GEOS-5 met fields were done with a 4-year spinup and were computed by Hongyu Liu.
  • For v9-02r, tropopause values for June and July 2012 were used as estimates for June and July 2013 and were computed by Karen Yu.
  • The simulations for GEOS-Chem v10-01 and later versions were done with a 4-year spinup and were completed by the GEOS-Chem Support Team.

Global Tropospheric Mean Aerosol Optical Depth

The table below lists the mean annual global tropospheric AOD (unitless) of several aerosol species at 550 nm. All values are calculated using area-weighted results of the 1-year benchmark simulation at 4° x 5° resolution.
