Abstract

This paper describes ongoing research on wind lidar techniques and measurements. Joint work between Utah State University and NASA's Goddard Space Flight Center has led to several field campaigns over the last three years involving the HARLIE holographic lidar and its use to determine vertical profiles of the horizontal wind. New data analysis methods have been developed at the Space Dynamics Laboratory for remote sensing of the wind speed and direction as functions of altitude. The third stage of HARLIE analysis is now automated to the extent that manual curve matching is optional. Automation has also been developed for analyzing the video images of overhead clouds, so that their motions can be compared with wind data from HARLIE and other instruments. Refinements and multi-sensor cross-checks of the data analysis methods will continue, as new campaigns are being planned. The long term goal of this work is to achieve a robust, non-Doppler wind sensing capability for use in the Calibration/Validation program for airborne and space-borne wind lidar instruments.
