In the spring of 2002 the Goddard Lidar Observatory for Winds (GLOW) was operated at the Homestead profiling site in western Oklahoma as part of the International H2O Project (IHOP). GLOW is a mobile direct detection Doppler lidar system which operates at the eyesafe wavelength of 355 nm. Vertical profiles of wind speed and direction are obtained with the lidar using the double edge technique to measure the Doppler shift of the laser signal backscattered by air molecules. During the IHOP campaign over 240 hours of wind profiles were obtained with the GLOW lidar in support of a variety of scientific investigations. In this paper we present a summary of IHOP operations including example case studies and results of inter-comparisons with data from other available wind sensors.
