The vertical allocation of emissions has a major impact on results of Chemistry Transport Models. However, in Europe it is still common to use fixed vertical profiles based on rough estimates to determine the emission height of point sources. This publication introduces a set of new vertical profiles for the use in chemistry transport modeling that were created from hourly gridded emissions calculated by the SMOKE for Europe emission model. SMOKE uses plume rise calculations to determine effective emission heights. Out of more than 40,000 different vertical emission profiles 73 have been chosen by means of hierarchical cluster analysis. These profiles show large differences to those currently used in many emission models. Emissions from combustion processes are released in much lower altitudes while those from production processes are allocated to higher altitudes. The profiles have a high temporal and spatial variability which is not represented by currently used profiles.
排放的垂直分配对化学传输模型的结果有重大影响。然而，在欧洲，仍常使用基于粗略估计的固定垂直廓线来确定点源的排放高度。本出版物介绍了一套新的垂直廓线，用于化学传输建模，这些廓线是由欧洲排放模型 SMOKE 计算的每小时网格化排放创建的。SMOKE 使用羽流抬升计算来确定有效排放高度。在 40000 多个不同的垂直排放廓线中，通过层次聚类分析选择了 73 个廓线。这些廓线与许多排放模型中当前使用的廓线有很大的不同。燃烧过程的排放释放到更低的高度，而生产过程的排放则分配到更高的高度。这些廓线具有很高的时间和空间变异性，这是当前使用的廓线所无法体现的。
