Lidar Uncertainty Measurement Experiment (LUMEX) – An Overview
1. Characterize sampling error for vertical velocity statistics
2. Analyze sensitivities of different Doppler lidar systems
3. Compare various single and dual Doppler retrieval techniques
4. Characterize error of spatial representativeness for separation distances up to 3 km
5. Validate turbulence analysis techniques and retrievals from Doppler lidars
This experiment brought together 5 Doppler lidars, both commercial and research grade, for a period of three weeks for a comprehensive inter-comparison study. The Doppler lidars were deployed at the Boulder Atmospheric Observatory site in Erie, site of a 300 m meteorological tower. This tower was instrumented with six sonic anemometers at levels from 50 m to 300 m with 50 m vertical spacing. A brief overview of the experiment outline and deployment will be presented. Results from the sampling error analysis and its implications on scanning strategy will be discussed. Results from inter-comparison of retrieval techniques and error of spatial representativeness analysis will be presented to discuss the importance of the choice of scanning strategy and retrieval algorithm based on the application, such as boundary layer studies or wind energy.
