大气边界层（ABL）中的化学是由表面通量、流动、湍流输运和化学反应等复杂过程控制的。我们提出了一个新的SOSA（模拟有机蒸汽和硫酸浓度的模型），并试图利用芬兰Hyyti¨¨a的SMEAR II的塔测量数据和邻近气象站的可用探测数据重建植被冠层及其上方ABL的排放，运输和化学。利用上边界条件的探测数据，并将模型推至表层的塔测量，我们能够通过ABL得到湍流和其他量的合理描述。作为该模型的第一个应用，我们给出了有机化合物的垂直剖面，并讨论了它们与新形成的颗粒的关系。
Chemistry in the atmospheric boundary layer (ABL) is controlled by complex processes of surface fluxes, flow, turbulent transport, and chemical reactions. We present a new model SOSA (model to simulate the concentration of organic vapours and sulphuric acid) and attempt to recon- struct the emissions, transport and chemistry in the ABL in and above a vegetation canopy using tower measure- ments from the SMEAR II at Hyyti¨¨ a, Finland and avail- able soundings data from neighbouring meteorological sta- tions. Using the sounding data for upper boundary condition and nudging the model to tower measurements in the sur- face layer we were able to get a reasonable description of turbulence and other quantities through the ABL. As a first application of the model, we present vertical profiles of or- ganic compounds and discuss their relation to newly formed particles.
