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.

罗森 该项目包括同时从北方半球中纬度站点（怀俄明州的拉勒米，41（N））和南半球中纬度站点（新西兰的Lauder，45（S））进行气球探测。 新开发的气球载仪器将用于获得整个对流层和平流层在两个波长、臭氧、相对湿度、空气温度和压力的气溶胶后向散射的高分辨率剖面。 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。 具体来说，最后的衰变山。将记录1991年皮纳图博火山爆发，并确定平流层气溶胶本底强度的新值。 对劳德上空对流层的测量将有助于解决南半球偏远地区普遍缺乏与对流层气溶胶有关的高垂直分辨率数据的问题。 对北方和南方中纬度站点的气溶胶进行直接比较，应能为确定大气过程和评估人为因素提供独特的对比数据。
