北极是一个快速变化的生态系统，与中纬度地区相比，复杂的气溶胶-云-气候反馈导致该地区变暖更快。了解颗粒物数量、浓度和粒度分布的变化对于限制人类活动对该区域影响的估计十分重要。在六年的半连续测量的粒子数尺寸分布附近的Utqiahovik（巴罗），阿拉斯加州，37个颗粒生长事件进行了观察。大多数事件发生在春季和夏季，6月份的月最大值，类似于其他北极网站。根据后向气团轨迹分析，受海洋气团（46%）和普鲁德霍湾气团（33%）影响的颗粒物增长事件数量相似，尽管空气主要来自北冰洋（75 ± 2%的天数），而普鲁德霍湾（8 ± 2%的天数）。相应的归一化粒子增长事件频率表明，从普鲁德霍湾的排放量可能会导致平均92个粒子增长事件，超过所有其他空气质量源的总和，在巴罗每年。普鲁德霍湾目前是美国第三大油气田，随着夏季海冰的减少，北极地区的开发预计将在整个世纪扩大。由于人类活动导致的粒子数浓度升高可能会通过直接、间接和地表的反作用，特别是通过增加云凝结核，对北极的气候变化产生深远的影响。
The Arctic is a rapidly changing ecosystem, with complex aerosol-cloud-climate feedbacks contributing to more rapid warming of the region as compared to the mid-latitudes. Understanding changes to particle number concentration and size distributions is important to constraining estimates of the effect of anthropogenic activity on the region. During six years of semi-continuous measurements of particle number size distributions conducted near Utqiaġvik (Barrow), Alaska, 37 particle-growth events were observed. The majority of events occurred during spring and summer with a monthly maximum in June, similar to other Arctic sites. Based on backward air mass trajectory analysis, similar numbers of particle-growth events were influenced by marine (46%) and Prudhoe Bay air masses (33%), despite air primarily coming from the Arctic Ocean (75 ± 2% of days) compared to Prudhoe Bay (8 ± 2% of days). The corresponding normalized particle-growth event frequency suggests that emissions from Prudhoe Bay could induce an average of 92 particle-growth events, more than all other air mass sources combined, at Barrow annually. Prudhoe Bay is currently the third largest oil and gas field in the United States, and development in the Arctic region is expected to expand throughout the 21st century as the extent of summertime sea ice decreases. Elevated particle number concentrations due to human activity are likely to have profound impacts on climate change in the Arctic through direct, indirect, and surface albedo feedbacks, particularly through the addition of cloud condensation nuclei.
