Collaborative Research: High-resolution Study of Atmosphere, Ice, and Aerosol Interactions in Coastal Antarctica

研究人员试图对南极洲沿海罗斯岛地区的气溶胶成分和大小进行高分辨率的时间和大小分布测量。气溶胶质谱仪（AMS）将用于提供硫酸盐、硝酸盐、氯化物、铵和有机碳等非难熔亚微米气溶胶颗粒的近实时定量尺寸和化学质量载荷信息。额外的测量将包括气溶胶尺寸与重叠的尺寸范围从20纳米到100微米，和颗粒进入液体取样的散装离子成分分析较大的气溶胶颗粒。AMS对气溶胶的连续监测的优点包括能够观察到新粒子成核事件的偶然性和短持续时间，从而捕捉到南极海洋气象条件的极端变化。这些气溶胶测量可能会引起其他学科的兴趣。培养一名博士后，并为极地trec参与者提供研究经验，将产生更广泛的影响。

Researchers seek to make high-resolution temporal and size distribution measurements of aerosol composition and size in the Ross Island region, coastal Antarctica. An Aerosol Mass Spectrometer (AMS) will be used to provide quantitative size and chemical mass loading information, in near real-time of non-refractory sub-micron aerosol particles such as sulfate, nitrate, chloride, ammonium, and organic carbon species. Additional measurements will include aerosol sizing with overlapping size ranges from 20 nm to 100 um, and particle into liquid sampling for bulk ionic compositional analysis of larger aerosol particles. Advantages in continuous AMS monitoring of aerosol include being able to observe the episodic nature and short duration of new particle nucleation events, thus capturing the extreme variability of meteorological conditions expected in maritime Antarctica. These aerosol measurements are likely to be of interest to other disciplines. Training of a post-doctoral associate, and research experience for a Polar-TREC participant are allied broader impacts.
