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

拟议的调查将为TOPSE空中实验提供NSF/NCAR C-130研究飞机上选定的酸性气体和气溶胶物种的测量。TOPSE是关于春分实验的对流层臭氧产生，该实验是一个多研究者计划，旨在研究从冬季到春季条件过渡期间中纬度到极地北半球臭氧和其他污染物化合物的产生和输送。这项研究的主要焦点是HNO3，另外还测量了SO2、HCOOH、CH3COOH和自然产生的放射性核素210Pb、7Be和10Be。这些测量将涉及活性氮的来源、分配和循环、极地春季有机化合物的光化学以及研究期间遇到的气团的来源等问题。

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.
