Aerosol and Ozone Measurements at Mid-Latitudes in the Northern and Southern Hemispheres

该项目包括在北半球（Laramie, Wyoming, 41(N)）和南半球（Lauder, New Zealand, 45(S)）的一个中纬度地点同时进行气球探测。新研制的气球载仪器将用于获取气溶胶后向散射在两个波长、臭氧、相对湿度、整个对流层和平流层的气温和气压的高分辨率剖面。这些结果将有助于目前在这两个地点建立的大气测量记录，并创造新的知识。具体地说，1991年皮纳图博火山喷发的最终衰减将被记录下来，并确定平流层气溶胶背景大小的新值。兰黛上空的对流层测量将有助于解决普遍缺乏与遥远南半球对流层气溶胶有关的高垂直分辨率数据的问题。对北部和南部中纬度地点的气溶胶进行直接比较，应该为确定大气过程和评估人为成分提供独特的对比数据。

ATM-9500186 Rosen This project involves concurrent balloon soundings from a mid-latitude site in the northern hemisphere (Laramie, Wyoming, 41(N), and a mid-latitude site in the southern hemisphere (Lauder, New Zealand, 45(S). Newly developed balloon borne instrumentation will be employed to obtain high resolution profiles of aerosol backscatter at two wavelengths, ozone, relative humidity, air temperature and pressure throughout the troposphere and stratosphere. The results will contribute to the present established record of atmospheric measurements at both sites as well as create new knowledge. Specifically, the final decay of the Mt. Pinatubo eruption of 1991 will be documented and a new value for the magnitude of stratospheric aerosol background determined. The tropospheric measurements over Lauder will help address the general lack of high vertical resolution data that is available relating to tropospheric aerosols in the remote southern hemisphere. A direct comparison of aerosols at the northern and southern mid-latitude sites should provide uniquely contrasting data for the identification of atmospheric processes and the assessment of anthropogenic components.
