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机载实验提供选定的酸性气体和气溶胶种类的测量，这些测量将搭载在NSF/NCAR C-130研究飞机上。TOPSE是关于春分的对流层臭氧生成实验，这是一个由多个研究者组成的项目，旨在研究从冬季到春季过渡期间中纬度到极北半球臭氧和其他污染物化合物的产生和运输。这次调查的主要重点是HNO3，另外还测量了SO2、HCOOH、CH3COOH以及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过程中遇到的气团的起源等问题。

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.
