Four Guiding Lights
NSF Consortium of Resonance andRayleigh Lidars
The Na Wind/Temperature lidars have reached a level of robust and reliable operation whose measurements and scientific contributions makethem an essential community asset.
Often a centerpiece instrument, the lidar technique providesthe most comprehensive measurement of range-resolved, neutralgas properties in the middle atmosphere and lower thermosphere.
What is CRRL?
A university-based lidar consortium with applications tomiddle and upper atmosphere research.

Operations & Maintenance
Facility Challenges: Keeping all Elements Well Balanced
Facility Challenges: As a University-Based Facility, Budgets Impact Students
Students serve as the work force for operations, maintenance, technology development, science productivity, and future innovations.
Facility budget fluctuations and pressures related to operations and data for community usage has a direct impact on students whose support requires consistency and stability to complete degrees
