Measurements of aerosol backscatter at two wavelengths, ozone concentration, relative humidity, and temperature will be obtained from balloons up to altitudes of 30 km, providing high resolution vertical profiles. Monthly flights will be carried out from Natal, Brazil. These measurements will serve to define the natural aerosol background and identify perturbations occurring throughout the free troposphere. These measurements will add information on a very undersampled region and provide the opportunity to study sources of aerosols in the tropics, their transport, and radiative impact.

将从30公里高空的气球上获得两个波长的气溶胶后向散射、臭氧浓度、相对湿度和温度的测量结果，提供高分辨率的垂直剖面图。每月将从巴西的纳塔尔执行航班。这些测量将用于确定自然气溶胶背景，并确定整个自由对流层发生的扰动。这些测量将增加关于一个非常采样不足的区域的信息，并为研究热带地区的气溶胶来源、其传输和辐射影响提供机会。
