NSF Award 1228464

21 Sept. 2012 - 31 August 2015.

NSF Award 0924407

1 Sept. 2009 - 31 August 2012.

The main focus of our research is the development and testing of the ability to retrieve 2-component vector wind fields from a eye-safe, scanning elastic backscatter lidars. Funding from our first award (NSF AGS 0924407) enabled us to compare vector components retrieved from the cross-correlation technique to vector components measured by tower-mounted sonic anemometers between 10 and 30 m AGL. Funding from our second award (NSF AGS 1228464) enabled us to retrieve vectors with a new wavelet-based optical flow motion estimation algorithm and compare results with velocity estimates from cross-correlation and winds measured independently by Doppler lidar between 50 m and 150 m AGL. The second award also supported a significant field experiment at the CSU Chico University Farm from June 2013 to January 2014. A supplemental award on AGS 1228464 allowed us to test the ability of the technique to retrieve the wind field over the ocean in March 2015. Our most recent award (NSF AGS 2054969) will utilize this unique observational capability to test new theories on the structure of surface layer turbulence.
