Tropospheric Sulfur Dioxide Measurement Intercomparison

本研究涉及1994年美国国家科学基金会（nsf）资助的对流层二氧化硫（SO2）测量的雾室法的参与。相互比较将由特拉华大学协调，暂定于1994年9月和10月在特拉华的刘易斯进行。来自新罕布什尔大学的两名研究人员将在GASIE比对期间操作雾室方法。雾室法似乎适合在偏远地区的大气化学测量项目中进行现场部署，因为它非常敏感，检测限约为20 pptr (v)，似乎不受基体干扰，尺寸和重量相对较小，而且实施成本适中。雾室法测量二氧化硫的可靠性将通过参加严格的双盲GASIE相互比较进一步检验。在该方法未来用于大型现场测量项目之前，这种参与是验证该方法的重要下一步。

This research pertains to the participation of the mist chamber method for measuring tropospheric sulfur Dioxide (SO2) in the 1994 NSF-sponsored intercomparison (GASIE). The intercomparison will be coordinated by the University of Delaware, and is tentatively planned for September and October of 1994 in Lewes, Delaware. Two researcher from the University of New Hampshire will operate the mist chamber method during the GASIE intercomparison. The mist chamber method appears desirable for field deployment in atmospheric chemistry measurement programs in remote regions because it is quite sensitive a detection limit of approximately 20 pptr (v) , appears to be free from matrix interferences is relatively small in size and weight, plus offers modest implementation costs. The reliability of the mist chamber method for measuring SO2 will be further tested by participation in the rigorous double-blind GASIE intercomparison. This participation is an essential next step in the validation of the method prior to its future use in large field measurement programs.
