A Strong Record of Technology Investment for Wind Measurements

Coherent Detection: • Demonstration of a hardened diode-pumped 2-µm laser (Kavaya/LaRC - IIP04)• Lab build and demonstration of integrated heterodyne photoreceiver (Amzajerdian/LaRC -

LRRP)• Integrated lidar photo receiver and sensor development (Abedin/LaRC - LRRP) • Development of an advanced optical heterodyne receiver (Mansour/JPL - ATI 99)• Laser diode characterization and lifetime demonstration (Amzajerdian/LaRC – LRRP)• Airborne demo of autonomous coherent-detection, pulsed, 2-micron, Doppler wind lidar

system (Kavaya/LaRC-IIP07)Direct Detection:

• Control and monitoring of laser thermal systems (Butler/GSFC - LRRP), • Narrow band, single mode, single frequency UV laser and space qualified etalon assembly for

O3 measurement (Gentry/GSFC -IIP04, ACT05)• Developed a high-power single frequency UV laser transmitter (Austin, Lite Cycles – SBIR

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)

UAVSARThe 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.
