LIDAR LOCATION : We have a mobile DIAL system. The whole system is installed in a truck, generally located to Centro Laser, Valenzano (Bari) Italy ( 41.01.200 North, 016.54.190 East)

SITE ELEVATION: sea level

PARAMETER(S) OR CONSTITUENT(S) MEASURED: NO2, SO2, O3, benzene, Toluene, water vapor, depolarization ratio

RESEARCH OBJECTIVES AND SPONSOR: to control air quality and climatic effects; to make quantitative analysis of anthropogenic emissions such as mobile vehicle exhaust or industrial plumes and the way they affect human health

MEASUREMENT TECHNIQUE: Differential Absorption Lidar for pollutants and water vapor.

MEASUREMENT RANGE: until 4 km

VERTICAL RESOLUTION: minimum resolution: 15 m

FREQ. OF MEASUREMENT (TYPICALLY): A measurement campaign every 4 month

MEASUREMENT TIMES (TYPICALLY): 1 week to prepare the whole system and 2 hours to begin the measurement.

LASER TYPE AND WAVELENGTH (s): Ti:Sapphire (700-900 nm) and non linear mixing between Ti:Sapphire and Nd:YAG (250-480 nm)

LASER ENERGY/PULSE: 100 mJ (at 780 nm for fundamental Ti:Sapphire ) and typical output energy is 20 mJ in the 450 nm region and 2-5 mJ in the 300 nm region.

PULSE REPETITION RATE: 10 Hz

RECEIVER SIZE AND CONFIGURATION: Newtonian telescope (f = 600 mm, f = 1600 mm, field of view = 1 mrad), monostatic system
