Figure 1. High resolution (1.5 m by 0.1 s) Polarization Diversity
Lidar height-time display of relative returned 0.532-micron laser power
from a cirrus cloud generated by hurricane Nora observed at the SGP CART
site near Lamont, Oklahoma on 26 September 1997. Units are relative
and are based on a logarithmic grayscale.
Figure 2. Radar during the Citation flight. Strongest returns
are indicated by white, weakest by black.
Figure 3. Linear depolarization ratios (delta, see color scale
at top), calculated from the cirrus cloud in Fig. 1, reveal low values (0.0
to 0.05),which are characteristic of horizontally oriented ice crystals.
