例如，阿拉伯半岛导致j（O（1 D））减少高达40%。本文用含时的零维化学模式研究了MBL中微量气体和参数的日变化。从模型中得出的RO* 2的昼夜行为和测量中观察到的显着差异进行了鉴定。测得的甲醛浓度与模型结果不同，最好的解释是一些缺失的化学物质，涉及少量的氯。介绍并讨论了描述这两种效应的其他可能过程。索引术语：0322大气组成和结构：组成源和汇; 0365大气组成和结构：对流层组成和化学; 3307气象学和大气动力学：边界层过程; 3339气象学和大气动力学：海洋/大气相互作用（0312，4504）;关键词：过氧自由基，INDOEX，氯，非甲烷烃，光解频率，甲醛
Arabia causing, for instance, a reduction in j(O( 1 D)) by up to 40%. The diurnal behavior of the trace gases and parameters in the MBL has been investigated by using a timedependent zero-dimensional chemical model. Significant differences between the diurnal behavior of RO* 2 derived from the model and observed in measurements were identified. The measured HCHO concentrations differed from the model results and are best explained by some missing chemistry involving low amounts of Cl. Other possible processes describing these two effects are presented and discussed.
