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 except for GEOS-Chem High Performance (HP) simulations which are at C24 resolution regridded to 1° x 1.25°.

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.
