| Zusammenfassung |
| A new optical sensor, the airborne Polar
Nephelometer, is described. The sensor is designed to measure the optical and
microphysical parameters of clouds containing either water droplets or ice
crystals or a mixture of these particles ranging in size from a few micrometers
to about 500 µm diameter. The probe measures the scattering phase function of
an ensemble of cloud particles intersecting a collimated laser beam near the
focal point of a paraboloïdal mirror. The light scattered from polar angles
from 3.49° to 169° is reflected onto a circular array of 33 photodiodes. The
signal processing electronics and computer storage can provide one measurement
of the scattering phase function every 100 ms or every 0.2 ms. The first part of
the paper describes the theoretical design of a prototype version of the probe. |
