Short Summary

This study calibrated a Raman water vapor lidar using tower-based in-situ humidity measurements at the Cabauw Experimental Site, demonstrating its stability with a day-to-day calibration constant variability of less than 2% and good agreement with radiosonde data.

Objective

• To calibrate a Raman water vapor lidar using tower-based in-situ humidity measurements and evaluate its stability throughout the year.

Study Configuration

• Spatial Scale: Point (200 m above ground level) for direct lidar-tower comparison; vertical profiles for lidar and radiosonde comparisons.
• Temporal Scale: Year-long evaluation for stability; high time resolution for direct comparisons; day-to-day variability assessment.

Methodology and Data

• Models used: Not applicable (instrument calibration study).
• Data sources: Tower-based in-situ humidity measurements, Raman water vapor lidar profiles, operational radiosonde data.

Main Results

• The Raman water vapor lidar was successfully calibrated using tower-based in-situ humidity measurements.
• Calibrated lidar water vapor profiles showed no significant difference when compared with operational radiosonde data.
• The day-to-day variability of the lidar's calibration constant was found to be smaller than 2% for both day and nighttime operations, indicating high stability.

Contributions

• Provides a robust calibration method for Raman water vapor lidars using readily available tower-based measurements.
• Demonstrates the long-term stability and reliability of the calibrated lidar system for atmospheric water vapor profiling.
• Validates lidar performance against established radiosonde data, enhancing confidence in lidar measurements.
