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.本数据集于美国阿拉斯加州扑克弗拉特研究靶场（Poker Flat Research Range, PFRR）开展自2016年起的长期大气观测：采用连续炭黑监测系统（continuous soot-monitoring system, COSMOS）与红外吸收光度计（infrared absorption photometer, 48iTLE），同步获取大气黑碳（black carbon, BC）质量浓度及一氧化碳（carbon monoxide, CO）混合比数据。本次观测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，并可为湿去除速率约束条件、重要排放源（包括周边北方森林火灾及经远程传输而来的亚洲排放源）的排放强度提供参考数据。若需使用本数据集，建议联系项目负责人。
