Abstract

ABSTRACT The first results of high spatial resolution modeling of the dispersion of atmospheric pollutant emissions from mobile sources in Antarctica are presented. Options for assessing the impacts of vehicles on air quality in Antarctica are discussed using the Belarusian Antarctic Station at Vecherny Oasis, Enderby Land, as an example. Sources of input data and collection and processing of these data are described. Surface air concentrations of nitrogen dioxide (NO2), and concentrations and dry atmospheric deposition levels of respirable suspended particulate matter (PM10) are estimated for different averaging periods and scenarios of the volume and spatial allocation of emission. Nowadays, the number of vehicles in the oasis is small. However, by the estimates, the maximum hourly concentrations of PM10 and NO2 at certain locations and under certain conditions could reach perceptible share of the air quality guideline value. Some other Antarctic stations have significant vehicle population, and assessment of their air impacts will be especially important. Suggestions for improvements of the quantitative assessment of impacts of mobile emission sources in Antarctica are proposed.

南极洲大气污染物从移动源扩散的评估:以维切尔尼绿洲为例

摘要:本文首次提出了南极洲移动源大气污染物扩散的高空间分辨率模拟结果。本文以位于恩德比地韦切尔尼绿洲的白俄罗斯南极站为例，讨论了评估车辆对南极洲空气质量影响的备选办法。描述了输入数据的来源以及这些数据的收集和处理。在不同排放量和空间分配的平均周期和情景下，估算了地表二氧化氮(NO2)浓度、可吸入悬浮颗粒物(PM10)浓度和干大气沉降水平。如今，绿洲上的车辆数量很少。然而，根据估计，在某些地点和某些条件下，PM10和NO2的最大小时浓度可以达到空气质量指标值的可感知份额。其他一些南极站有大量车辆，评估它们对空气的影响将特别重要。提出了改进南极洲移动排放源影响定量评估的建议。

期刊介绍： Polar Geographyis a quarterly publication that offers a venue for scholarly research on the physical and human aspects of the Polar Regions. The journal seeks to address the component interplay of the natural systems, the complex historical, political, economic, cultural, diplomatic, and security issues, and the interchange amongst them. As such, the journal welcomes comparative approaches, critical scholarship, and alternative and disparate perspectives from around the globe. The journal offers scientists a venue for publishing longer papers such as might result from distillation of a thesis, or review papers that place in global context results from coordinated national and international efforts currently underway in both Polar Regions.
