16 July 2013: Dr. Jakob Mann from Technical University of Denmark to visit CSU Chico. He will give a seminar entited: How can Doppler lidars measure turbulence in the lowest part of the atmosphere? on Tuesday, 16 July 2013, 9 AM in PHSC 202.

13 June 2014: Increasing Research Capacity: a new electrical power distribution system installed will enable us to run multiple lidar systems simultaneously. 320 amps at 240V are now available.
