2. NOAA and DoD, through NPOESS/IPO, have been funding risk reduction, calibration/validation, research and simulation studies related to Wind Profiling LIDAR for several years. • Risk Reduction Efforts • Requirements definitions and refinements, realizability studies • LIDAR scatterers’ distributions and characterization studies • Ground based Wind LIDAR Validation Systems • Airborne Validation of the Concept [DDWL (various), CDWL, Hybrid] • LIDAR Technology Studies e.g. HOE, Tunable LOs, Detectors, efficient, long-life, high-rep Lasers • Hybrid DWL feasibility studies; Adaptive Targeting studies • Platform Accommodation Studies [airborne & spaceborne (incl. NPOESS, NPOESS Lite)] • Calibration/Validation of space-based WL • Ground ( stationary and mobile) system development & demonstrations • Airborne system development & demonstrations • Utilization of Sondes [Rawinsondes, Dropsondes]; Collateral measurements req. (e.g. aerosols) • Comparison of “truth techniques” for space based WL • OSSEs [Observing System Simulation Experiments] & OSEs • Showing the relative benefits of various Space-based DWL concepts. • Space based Doppler Wind LIDAR Mission Studies – Demonstration NWOS • BalloonWinds – NOAA/NESDIS Office of Systems Development • International Space Station Wind Lidar Study- NASA/GSFC IDL/MDL • NOAA/NESDIS/OSD co-sponsoring w/NASA & USAF NOAA / NESDIS Wind Lidar Activities

4. The National Research Council (NRC) Decadal Survey report published in 2007 recommended a global wind mission - The NRC Weather Panel determined that a hybrid Doppler Wind Lidar (DWL) in low Earth orbit could make a transformational impact on global tropospheric and stratospheric analyses Independent modeling studies at NCEP, ESRL, NASA and ECMWF show tropospheric wind profiles to be the single most beneficial measurement for numerical weather prediction that is absent from the current Global Observing System The measurement of accurate global winds is also critical for climate monitoring; improved reanalysis data sets are especially needed to provide a more accurate environmental data record to study global warming Background

5. DWL technology is basically ready to be demonstrated in space, but a mission focus is needed NASA is investing very little resources into critical mission activities because of the “tier 3” status of a winds mission even though it continues its large critical technology development In a 9/22/09 letter, the Air Force Director of Weather recently renewed the offer to NASA’s Associate Administrator, Science Mission Directorate, first made in August 2007, to sponsor a NASA winds space demonstration in the DoD Space Experiments Review Board (SERB) via the Space Test Program (STP); this could provide a large benefit to NASA in terms of defraying launch costs NOAA (NESDIS/OSD) and DoD (USAF/ORS) are contributing to the NASA-led ISS DWL feasibility study because of the potential benefit to a broad range of NOAA and DoD programs [see next chart for NOAA Program examples] Background [continued]
