采用美国Artium Technologies公司的机载相位多普勒粒子干涉仪PDI-FP,可以测量云层中微小水滴的粒径和速度分布。可以测量云层中的液态水含量LWC。
Conducting accurate cloud microphysical measurements from
airborne platforms poses a number of challenges. The technique of
phase Doppler interferometry (PDI) confers numerous advantages
relative to traditional light-scattering techniques for measurement
of the cloud drop size distribution, and, in addition, yields drop
velocity information. Here, we describe PDI for the purposes of
aiding atmospheric scientists in understanding the technique fundamentals,
advantages, and limitations in measuring cloud microphysical
properties. The performance of the Artium Flight PDI,
an instrument specifically designed for airborne cloud measurements,
is studied. Drop size distributions, liquid water content, and
velocity distributions are compared with those measured by other
airborne instruments.
