Short Summary

This paper describes the development and technical setup of a novel 532.25 nm coherent Doppler lidar (CDL) and demonstrates its capability to simultaneously observe diverse atmospheric particles and detect the Rayleigh-Brillouin spectrum for Mie signal calibration.

Objective

• To develop and characterize a novel 532.25 nm coherent Doppler lidar (CDL) system with a 3.2 GHz data acquisition rate.
• To demonstrate the CDL's ability to simultaneously observe cloud, precipitation, and aerosol particles across a wide size range within a single Doppler spectrum.
• To demonstrate the coherent detection of the broadband Rayleigh-Brillouin (RB) spectrum and its potential for Mie signal calibration.

Study Configuration

• Spatial Scale: Local atmospheric column (demonstrated through atmospheric measurement cases).
• Temporal Scale: Short-term atmospheric observation periods (demonstrated through atmospheric measurement cases).

Methodology and Data

• Models used: Not applicable (instrument development and atmospheric observation).
• Data sources: Atmospheric observations (generated by the developed 532.25 nm coherent Doppler lidar).

Main Results

• A coherent Doppler lidar operating at 532.25 nm wavelength with a 3.2 GHz data acquisition system was successfully developed and its technical setup described.
• The instrument demonstrated the ability to observe cloud, precipitation, and aerosol particles of very different sizes simultaneously within a single Doppler spectrum.
• The system achieved coherent detection of the broadband Rayleigh-Brillouin (RB) spectrum, enabling the possibility for Mie signal calibration.

Contributions

• Development of a novel 532.25 nm coherent Doppler lidar, offering new capabilities and benefits compared to existing 1.55 µm CDLs.
• Demonstration of simultaneous observation of diverse atmospheric particles (cloud, precipitation, aerosol) with a single instrument.
• Introduction of a method for Mie signal calibration through coherent detection of the Rayleigh-Brillouin spectrum.
• The system's capabilities are identified as promising for advancing knowledge about aerosol-cloud interactions.
