Description
What is CRRL?
A university-based lidar consortium with applications tomiddle and upper atmosphere research.
Often a centerpiece instrument, the lidar technique providesthe most comprehensive measurement of range-resolved, neutralgas properties in the middle atmosphere and lower thermosphere.
Products:
The Na Wind/Temperature lidars have reached a level of robust and reliable operation whose measurements and scientific contributions makethem an essential community asset.0
