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
