Atmospheric Remote Sensing: Instruments
Airborne Aerosol Lidar (ABAEL)
Decommissioned
ABAEL is designed to detect aerosol layers in the atmosphere from an aircraft. It is deployed for air quality missions to locate aerosol layers for in-situ sampling and for mapping the regional distribution of aerosols.
Basic parameters measured:
- Aerosol backscatter
