全球三维拉格朗日化学输送模式STOCHEM被用来描述次生大气气溶胶的四种组分的对流层分布：硝酸盐、硫酸盐、铵和有机化合物。该模型描述了SO2、DMS、NOx、NH3和萜烯氧化形成的酸前体的详细化学过程，并将其吸收到气溶胶中。模型结果与可获得的地面观测结果进行了比较详细的比较。对全球预算和其他模型研究中发现的负担进行了比较。已经估计了工业前、现在和2030年排放的二次气溶胶总质量的全球分布，并估计了不同二次气溶胶组分的质量分数的较大变化。
A global 3-D Lagrangian chemistry-transport model STOCHEM is used to describe the tropospheric distributions of four components of the secondary atmospheric aerosol: nitrate, sulphate, ammonium and organic compounds. The model describes the detailed chemistry of the formation of the acid precursors from the oxidation of SO2, DMS, NOx, NH3 and terpenes and their uptake into the aerosol. Model results are compared in some detail with the available surface observations. Comparisons are made between the global budgets and burdens found in other modelling studies. The global distributions of the total mass of secondary aerosols have been estimated for the pre-industrial, present day and 2030 emissions and large changes have been estimated in the mass fractions of the different secondary aerosol components.
