Instrument: Ozone Lidar EXperiment

Name Ozone Lidar EXperiment
Acronym OLEX
Manufacturer DLR
Operated by DLR
Operated onboard

Instrument type

Name Aerosol LIDAR (LIght Detection And Ranging)
Acronym Aerosol LIDAR

Principle of operation

Measured parameter Aerosol backscatter coefficient
Operating principle

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
