VERITAS uses a lidar system provided by Vaisala. Our model is the CL51; here's the spec sheet.

Here is an article on the automatic monitoring of boundary layer structures using lidar systems.

Here's the output from the lidar:

VERITAS is located in southern Arizona, USA, approximately 70 km (50 miles) south of Tucson and a 15-minute drive from Interstate I-19 (exit 56 - Canoa Ranch).

From exit 56, proceed south on the service road (east of the Interstate) for about 3 km (2 mi), and turn left (east) on Elephant Head Road. Approximately 1 km (0.6 mi) after passing the Santa Cruz river, turn right (south) on Mt. Hopkins road and proceed 11 km (7 mi) to the FLWO basecamp.
