Mass concentration of BC(black carbon) measurement by COSMOS at Spasskaya Pad station, East Siberia, Russia

Long-term observations of atmospheric black carbon (BC) mass concentrations were aimed using a continuous soot-monitoring system (COSMOS) at Spasskaya Pad station, near Yakutsk in East Siberia, Russia. We aim to evaluate atmospheric chemical transport models and chemistry-climate models used for IPCC assessment reports and to provide information on wet removal rate constraints and the emission strengths of important sources (nearby boreal forest fires and Asia, after long-range transport).本研究采用连续烟尘监测系统（COSMOS），在俄罗斯东西伯利亚雅库茨克附近的斯帕斯卡亚帕德站，对大气黑碳（black carbon, BC）质量浓度开展了长期观测。本研究旨在评估用于政府间气候变化专门委员会（Intergovernmental Panel on Climate Change, IPCC）评估报告的大气化学传输模式与化学气候模式，并可为湿去除速率约束以及重要排放源（包括邻近区域的北方森林火灾与经长距离传输而来的亚洲排放源）的排放强度提供相关信息。
