2. Main features of the instrumental and data processing

The lidar was installed in 1988, as part of the Cuban-Soviet cooperation in tropical meteorology research, but only began regular operation in January 1992. Measurements were carried out on cloud free nights. Table 1 shows its main parameters.

Some times, under apparently clear sky conditions the initial set of shots, used to check the functioning of the lidar, reveals the presence of cirrus clouds. In those cases, these sets of shots have been saved. Beginning in 1993, these are done with resolution of 75 m, and beginning processing in the year 1995, with the manual algorithm..
