最近，在平流层测量活动中，美国航天局ER-2号飞机上搭载了一种新仪器，用于同时测量0.4-10微米的气溶胶直径和1.30-1.60的折射率。在70°S至50°N的纬度范围内，平流层平均折射率从1.40至1.42不等，在4至20公里的垂直范围内，平均折射率从1.34至1.46不等。测得的平流层折射率与理论预测不符，垂直分布图表明在7-9公里高度范围内存在非球形或吸收性粒子。
A new instrument for simultaneously measuring aerosol diameter from 0.4–10 µm and the refractive index between 1.30–1.60 has recently been flown on the NASA ER-2 aircraft during a stratospheric measurement campaign. Average stratospheric refractive indices varied from 1.40 to 1.42 over a latitude range from 70°S to 50°N and from 1.34 to 1.46 over a vertical range from 4–20 km. The measured stratospheric refractive indices do not agree well with theoretical predictions and vertical profiles suggest the presence of non-spherical or absorbing particles in the altitude range of 7–9 km.
