|Name||Aerosol LIDAR (LIght Detection And Ranging)|
|Measured parameter||Aerosol backscatter coefficient|
Laser pulses are transmitted, the backscattered radiation is collected in a telescope and measured by appropriate detectors. The ranging is done by measuring the pulse travel time. The backscattered signal contains information on the microphysical particle properties (aerosol Lidar).
|Measurement(s)||Active Remote Sensing|
|Operating mode||Remote sensing|
ABLE is a high-power lidar emitting at 532 and 355nm. It can fire in the vertical either above or below the aircraft. The firing direction is decided before each flight and cannot be changed in-flight. The system detects aerosols up to over 10 km from the aircraft.
Aerosol backscattered and depolarisation, 1-20km above the aircraft. Unlike ground based experiments, airborne Lidars are not limited to looking at the vertical column over the instrument, but can be quickly moved into an area of interest and look at any direction in the sky.
