A large polar nephelometer was flown on a high-altitude balloon to 26.6 km over New Mexico in June 1974 just before the incursion of Fuego volcanic dust. Angular-scattering intensity and polarization observations depict the vertical structure of absolute optical parameters and, as a result, the distribution of atmospheric aerosols. An uncommon phenomenon was detected at 25 km: a stratospheric cloud near the San Andres mountains. These data are compared to findings from a previous flight in November 1970 in which significant altitudinal variability in the atmospheric scattering phase function was evident.
1974年6月，就在富埃戈火山尘埃侵入之前，一台大型极地 nephelometer 搭载在高空气球上飞越新墨西哥州，到达26.6千米的高度。角散射强度和偏振观测描绘了绝对光学参数的垂直结构，进而描绘了大气气溶胶的分布。在25千米处检测到一种罕见现象：圣安德烈斯山脉附近的平流层云。这些数据与1970年11月之前一次飞行的结果进行了比较，那次飞行中大气散射相位函数存在明显的高度变化。
