Abstract
Cloud base height is an important parameter
for climate studies as well as aviation safety. Ceilometers or
LIDARs can measure this parameter but are usually
expensive instruments. In this paper, a low-cost method to
measure cloud base height based on consumer digital
cameras and stereophotogrammetry is presented. The
performance of the system is evaluated by comparison with
LIDAR measurements. It is shown that the prototype can
also measure the wind speed and direction at cloud height.
