Science Mission Directorate Meeting of the Working Group on Space-Based Lidar Winds: View from NASA Headquarters Ramesh Kakar Weather Focus Area Leader July 8, 2008

2 Recent Developments NASA has selected seven proposals for funding as a result of the ROSES07 Wind Lidar Science Announcement NASA plans to spend more than $3M over three years in support of these proposals The IIP selected two new Wind Lidar proposals in April 2008 NASA plans to support a “hurricane genesis” field experiment during the 2010 hurricane season and expects a hybrid wind lidar system to be the primary instrument for this experiment Dr. Ed Weiler replaced Dr. Alan Stern as SMD Associate Administrator in March 2008

Summary  Considerable activity related to the measurement of vector wind profiles is ongoing at NASA  The NRC Decadal Survey specifically calls out for space-borne demonstration of 3-D winds but puts this in the third tier of its recommendation  The NASA management is committed to implement the NRC advice strictly along the suggested sequence
