This article deals with the evaluation of chemical kinetics and photochemical data for use in atmospheric modeling. Models used to calculate the temporal and spatial variation of atmospheric trace gas composition are based on chemical schemes which require chemical kinetics data for the elementary reactions involved. These data derive from careful experimentation under conditions relevant for the atmosphere, carried out in laboratories worldwide using ever improving technology over the past 50 years. The article contains an account of the background issues of atmospheric composition change which have stimulated this branch of atmospheric science; this is followed by a section on parameterisation and evaluation of kinetics data. A description of currently available on-line databases is provided. The final section contains a short description of some recent significant improvement in knowledge of rate constants for key reactions of interest in stratospheric and tropospheric chemistry.
本文涉及化学动力学和光化学数据的评估，用于大气模拟。用于计算大气痕量气体成分的时空变化的模型是基于化学方案的，这些方案需要涉及的基本反应的化学动力学数据。这些数据来自于过去 50 年来，在全球范围内的实验室中，在与大气相关的条件下进行的精心实验，使用的技术不断改进。本文包含了激发大气科学这一分支的大气成分变化的背景问题的说明；接下来是关于动力学数据的参数化和评估的部分。提供了当前可用的在线数据库的描述。最后一部分简要描述了一些关于平流层和对流层化学中关键反应的速率常数的最新重要改进。
