利用1984-1994年第二次平流层气溶胶和气体实验（SAGE）的多波长气溶胶消光测量数据，发展了平流层气溶胶表面积密度的全球气候学。气溶胶表面积密度在15.5，20.5和25.5公里的空间和时间的变化，以及作为高度和纬度的函数的累积统计分布。在此期间，其中包括与1991年6月皮纳图博火山喷发以及1989-1991年的低负荷期间的气溶胶的注入和消散，气溶胶表面积密度变化超过30倍，在某些高度。对1991-1994年SAGE II和怀俄明州大学光学粒子计数器的气溶胶表面积密度进行了比较，结果表明，尽管存在一些差异，但总体上是一致的。还介绍了平流层气溶胶测量II（1978-1994）和SAGE（1979-1981）仪器使用单波长测量的气候学扩展。
A global climatology of stratospheric aerosol surface area density has been developed using the multiwavelength aerosol extinction measurements of the Stratospheric Aerosol and Gas Experiment (SAGE) II for 1984–1994. The spatial and temporal variability of aerosol surface area density at 15.5, 20.5, and 25.5 km are presented as well as cumulative statistical distributions as a function of altitude and latitude. During this period, which encompassed the injection and dissipation of the aerosol associated with the June 1991 Mount Pinatubo eruption as well as the low loading period of 1989–1991, aerosol surface area density varied by more than a factor 30 at some altitudes. Aerosol surface area density derived from SAGE II and from the University of Wyoming optical particle counters are compared for 1991–1994 and are shown to be in generally good agreement though some differences are noted. An extension of the climatology using single-wavelength measurements by the Stratospheric Aerosol Measurement II (1978–1994) and SAGE (1979–1981) instruments is also presented.
