Network Doppler Lidar for simultaneous multi-parameter observations

We present the development progress of our compact multi-field-of-view lidar units for investigating small- to large-scale processes in the atmosphere. Matched narrowband laser and receiver enable precise daylight aerosol measurements with high aerosol visibility and high Doppler wind sensitivity in the troposphere/stratosphere and above. We present recent results with focus on extended measurement capabilities of our transportable systems.

Daylight capable Doppler lidars are complex systems particularly as lidar arrays require compact units with automated functionality. To study the 3-dimensional structure of small- to large-scale atmospheric processes we developed a universal Doppler lidar platform with multiple fields of view. All required technologies are included for studying Mie scattering (aerosols), Rayleigh scattering (air molecules), and resonance fluorescence (potassium atoms) from the troposphere (5 km) to the thermosphere (100 km). We developed unique frequency scanning laser and filter techniques that enable multiple observations (wind, temperature, aerosols, metal density). The combination of narrowband emitter and receiver allow a spectral high resolved characterization of the backscattered Doppler signals with a high wind sensitivity and aerosol visibility. Our current developments focus on enhancing lidar measurement capabilities of multiple parameters together with transferring the technology into industry (Project LidarCUBE) and demonstration of lidar array with enhanced daylight capability (EULIAA – European Lidar Array for Atmospheric Climate Monitoring). We will show recent results of our unique lidar technique with focus on aerosol measurements and more.
