Airborne Measurements of Acidic Trace Gases and Aerosol Associated 210Pb, 7Be, and 10Be for the NSF/NCAR Tropospheric Ozone Production about the Spring Equinox (TOPSE) Experiment

拟议的调查将提供测量选定的酸性气体和气溶胶物种登上NSF/NCAR C-130研究飞机的TOPSE机载实验。 TOPSE是关于春分实验的对流层臭氧生产，这是一个多研究员方案，旨在研究从冬季到春季条件过渡期间中纬度到极地北方半球臭氧和其他污染物的生产和运输。 本次调查的主要重点是硝酸，与SO2，HCOOH，CH 3COOH和天然存在的放射性核素210铅，7 Be和10 Be的额外测量。 这些测量将解决的问题，涉及的来源，分区，和循环的活性氮，在极地春季的有机化合物的光化学，以及在研究过程中遇到的空气质量的起源。

The proposed investigation will provide measurements of selected acidic gases and aerosol species aboard the NSF/NCAR C-130 research aircraft for the TOPSE airborne experiment. TOPSE is the Tropospheric Ozone Production about the Spring Equinox experiment, which is a multi-investigator program designed to study the production and transport of ozone and other contaminant compounds over the mid-latitude to polar Northern Hemisphere during the transition from winter to spring conditions. The principal focus of this investigation is on HNO3, with additional measurements of SO2, HCOOH, CH3COOH, and the naturally occurring radionuclides 210Pb, 7Be, and 10Be. These measurements will address issues involving the sources, partitioning, and cycling of reactive nitrogen, the photochemistry of organic compounds in the polar springtime, and the origin of air masses encountered during the study.
