Wyoming Cloud Lidar (WCL)
STATUS
Operational
AVAILABILITY
The WCL is availble to work on both Wyoming King Air and C-130. It is available through NSF/ATM/LAOF deployment process. See http://flights.uwyo.edu and http://www.eol.ucar.edu/fps/OFAP/UserGuide.pdf
REQUEST PROCEDURE
Contact with Zhien Wang: zwang@uwyo.edu or Al Rodi: rodi@uwyo.edu
Airborne Measurements
The WCL is a compact polarization lidar. The goal of the WCL is to provide high spatial resolution cloud base measurements, as well as cloud extinction coefficient profiles which will complement Wyoming Cloud Radar observations and will work alongside of the WCR. Currently, we have two units to provide up and down measurements simultaneously from Wyoming King Air.
