Research Groups

This study developed a low-maintenance differential absorption lidar (DIAL) for continuous vertical water vapor profiling and validated its performance against a collocated Raman lidar, demonstrating good agreement between the two systems.

Objective

• Develop a low-maintenance differential absorption lidar (DIAL) capable of continuous vertical water vapor profile measurements.
• Validate the performance of the developed DIAL by comparing its measurements with those from a collocated Raman lidar.

Study Configuration

• Spatial Scale: Local, point-based vertical profiling.
• Temporal Scale: Continuous observation over an unspecified duration.

Methodology and Data

• Models used: Not applicable; the study focuses on instrument development and observation.
• Data sources: Direct observations from the developed Differential Absorption Lidar (DIAL) and a collocated Raman lidar.

Main Results

• A low-maintenance differential absorption lidar (DIAL) system was successfully developed.
• The developed DIAL continuously observed vertical water vapor profiles.
• The water vapor profiles measured by the DIAL showed good agreement with those obtained from a collocated Raman lidar.

Contributions

• Development and successful validation of a low-maintenance DIAL system, addressing a critical need for extensive lidar observation networks to enhance early prediction of heavy rainfall and mitigate water-related hazards.
• Demonstration of the DIAL's capability for continuous and accurate vertical water vapor profiling through direct comparison with a collocated, established Raman lidar.
