Mass concentration of BC(black carbon) measurment by COSMOS and mixing ratio of CO(carbon monoxide) measured by 48iTLE at Poker Flat Research Range (PFRR), Alaska, USA

Long-term (since 2016) observations of atmospheric black carbon (BC) mass concentrations and carbon moxide (CO) mixing ratio were performed using a continuous soot-monitoring system (COSMOS) and an infrared absorption photometer (48iTLE) at Poker Flat Research Range (PFRR), Alaska, USA. 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). It is recommended to contact the investigators for any use.

自2016年起，研究团队于美国阿拉斯加州扑克平地研究靶场（Poker Flat Research Range, PFRR），采用连续烟尘监测系统（continuous soot-monitoring system, COSMOS）与红外吸收光度计（infrared absorption photometer, 48iTLE），对大气黑碳（atmospheric black carbon, BC）质量浓度及一氧化碳（carbon monoxide, CO）混合比开展了长期连续观测。本数据集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型与化学-气候模型，并可为湿清除速率约束条件以及邻近区域的北方森林火灾、经长距离传输而来的亚洲排放源的排放强度提供数据支撑。若需使用本数据集，建议先行联系项目负责人。
