1 QuikScat and WindSat underflights with TODWL G. D. Emmitt, C. O'Handley and S. Greco Simpson Weather Associates Lidar Working Group Meeting Snowmass July 17 – 20 2007

2 Objectives Investigate the influence of OLEs and near surface jets on OVW retrievals and air-sea flux parameterizations Investigate the accuracy of PBL wind profiles derived for OVWs Obtain high spatially resolved wind profiles within footprint and processing “pixels” of both a scatterometer (QuikScat) and a polarmetric radiometers (WindSat)

3 April Underflights with TODWL and the STV Two underflights – 5:30 pm PDT April16, 2007 – 6:07 pm PDT April 18, 2007 Off coast near and over Monterey Bay Flight altitude of 1900 m Conical scanning down 500 m repeat
