在ACE-ASIA(气溶胶特性实验)期间,将在C-130飞机上进行二氧化硫(SO2)和二甲基硫(DMS)的测量。将部署一种新开发的仪器,该仪器能够以1赫兹的频率和1ppt的检测下限测量二氧化硫。该仪器基于大气压电离质谱仪(APIMS)。同位素标记的二氧化硫将被用作外部标准。快速的响应时间将使快速识别不同的大气层成为可能。ACE-Asia计划将特别关注城市污染层(二氧化硫含量高)和粉尘层,以及粉尘和二氧化硫的化学相互作用程度的问题。
英文摘要
Measurements of sulfur dioxide (SO2) and dimethyl sulfide (DMS) will be performed on board the C-130 aircraft during ACE-Asia (Aerosol Characterization Experiment). A recently developed instrument will be deployed that is capable of measuring SO2 at a frequency of 1 Hz and a detection limit of 1 ppt. The instrument is based on atmospheric pressure ionization mass spectrometery (APIMS). Isotopically labelled SO2 will be used as an external standard. The fast response time will make it possible to rapidly identify different atmospheric layers. Of particular interest in the ACE-Asia program will be urban pollution layers (high in SO2) and dust layers, and the question of the degree to which dust and SO2 interact chemically.
