Since the fall of 1986, cirrus clouds were observed with |
|
backscatter cross sections ranging from less than 1 x |
|
10(exp -7) to 4.2 x 10(exp -5)m/sr, optical thicknesses |
|
ranging from less than .003 to greater than 2.7, and bulk |
|
average backscatter phase functions from .02 to .065/sr. |
|
Cirrus cloud structures were recorded ranging in vertical |
|
extent from 0.1 to 8 km, having horizontal scales from |
|
10's of meters to 266 km, and exhibiting aspect ratios of |
|
from 1:5 to 1:100. The altitude relationship between |
|
cloud top and bottom boundaries and the optical center of |
|
the cloud is influenced by the type of formation |
|
observed. Cirrus morphology and generation processes |
|
appear to be related to the wind field. The high spectral |
|
resolution lidar (HSRL) was adapted to the task of cirrus |
|
cloud optical property measurement. The HSRL data |
|
reported were collected with the CuCl2 transmitter |
|
producing 50 mW of output power, achieving eye safe, |
|
direct optical depth and backscatter cross section |
|
measurements with 10 minute averaging times. |
