9 Earth Science Technology Office (ESTO) Stimulus-Funded Technology Development Global Hawk Instruments Stimulus-Funded Technology Development Global Hawk Instruments This task will Integrate the LVIS capability onto the Global Hawk and provide an automated, reliable package for high altitude measurements. Land, Vegetation, & Ice Sensor (LVIS) GOLD will enable, for the first time, Ozone LIDAR measurements from a high-altitude aircraft that support global atmospheric composition and climate change investigations. Global Ozone Lidar Demonstrator (GOLD) UAVSAR The Uninhabited Aerial Vehicle – Synthetic Aperture Radar (UAVSAR) project will install two existing UAVSAR pods on a UAV for the first time. On Global Hawk, UAVSAR will generate precise topographic maps and single-pass polarimetric interferograms of ice and vegetation. Earth Science Technology Office (ESTO) $ 1.6M $1.5M $4.4M
