黏性气溶胶核壳动力学模式（CSVA）
CSVA模式通过构建统一的气相扩散、界面传质及颗粒相扩散的传质方程，以化学反应的形式成功实现了对数百物种参与的气-粒传质过程以及数千个化学反应的在线耦合，涵盖了从成核、传质到多相反应的微观过程。该模式有效克服了传统有机气溶胶参数化方案面临的气溶胶化学成分缺失的局限，实现了从一般浓度模拟向微观过程模拟的转变，同时，由于考虑了水分子的气粒传质过程，因此CSVA模式还能从分子层面研究SOA与云雾的相互作用，为深入解析大气化学与云物理相互作用提供了可靠的数值实验平台。
A Core-Shell kinetic model for simulating Viscous secondary organic Aerosol (CSVA)
CSVA is a kinetic box model for simulating viscous secondary organic aerosol based on a Core-Shell configuration. In the CSVA model, all the processes are represented by "chemical reactions" in a unified form, including homogeneous nucleation, condensation and evaporation for organics (and water). The gas-particle mass transfer is described with the equivalent resistance, which links the gas-phase diffusion, interfacial mass transport and particle-phase diffusion(Jia & Xu, 2021).
