积累状态和云处理状态。这种解释意味着气溶胶源（气相成核）与气溶胶汇（云清除气溶胶粒子）密切相关。过程中，可以修改拟议的气溶胶生命周期进行了讨论。数的大小和表面积分布典型的各种气溶胶状态进行检查。对流层干气溶胶表面积在1 ~ 20 mm 2 cm 3之间，对流层顶干气溶胶表面积在2 ~ 13 mm 2 cm 3之间。提供了气溶胶粒径分布和总表面积浓度的参数化，以便于在大气模型中使用这些数据。索引术语：0305大气组成和结构：气溶胶和颗粒物（0345，4801）; 0322大气组成和结构：组成源和汇; 0368大气组成和结构：对流层-组成传输和化学
accumulation state, and a cloud-processed state. This interpretation implies that aerosol sources (nucleation from the gas phase) are closely tied to aerosol sinks (cloud scavenging of aerosol particles). Processes that could modify the proposed aerosol life cycle are discussed. Number size and surface area distributions typical for the various aerosol states are examined. The dry aerosol surface area ranges from 1 to 20 mm 2 cm � 3 in the free troposphere and from 2 to 13 mm 2 cm � 3 in the tropopause region. Parameterizations of the aerosol size distributions and total surface area concentrations are provided to facilitate the use of the data in atmospheric models.
