LIDAR NETWORK SYSTEM FOR MONITORING THE ATMOSPHERIC-ENVIRONMENT IN JAKARTA CITY

A lidar network system consisting of two Mie scattering lidars and one differential absorption lidar was developed to measure the atmospheri c environment in Jakarta. The three lidars were installed at three loc ations in Jakarta to study atmospheric boundary layer structure and tr ansportation of atmospheric pollutants. The Mie scattering lidars empl oy compact flashlamp pumped Nd:YAG lasers operated at 1064 nm fundamen tal. They are installed in shelters and directed vertically. One of th e Mie lidar has a rotating wedged window for scanning conically to mea sure wind velocity using a correlation method. The DIAL system employs two Nd:YAG laser-pumped optical parametric oscillators. The DIAL is d esigned to measure distribution of ozone and SO, in the near UV region , and NO2 in the 450-nm region. The system is installed in a shelter a nd has a full scanning capability.
