1. Enhancements in the Ground-Based Wind Measurement Capabilities near Huntsville, Alabama: Validation for Airborne & Space-Based Doppler Wind Lidars David Bowdle, Kevin Knupp, Mike Newchurch University of Alabama in Huntsville Presented at: Meeting of the Working Group on Space-Based Lidar Winds Monterey, California, February 5-8, 2008

2. ARMOR UPGRADES Advanced Radar for Meteorological and Operational Research (ARMOR) WSR 74C Doppler Radar located at the Huntsville Airport decommissioned, transferred to UAH 2004 upgraded to dual polarization new receiver, feedhorn, antenna controller partnership with WHNT-TV 2005/2006 new transmitter, pedestal, antenna Future relocate to reduce ground clutter?

3. MAX ACQUISTION Mobile Alabama X-band (MAX) Measurements X-band Doppler scanning dual polarimetric Platform truck-mounted Status operational winter 2008 enables dual-Doppler with ARMOR

4. MIPS UPGRADES Mobile Integrated Profiling System (MIPS) Existing Wind Measurements Doppler sodar profiler (two units) 915 MHz wind profiler X-band profiling radar scanning 2-  m Doppler lidar (MSFC) Proposed Wind Measurements long-range Doppler wind lidar short-range high-PRF Doppler wind lidar dual-polarization W-band Doppler radar profiler KaX-band dual-polarization scanning Doppler radar

5. POTENTIAL Wind Validation for Airborne and Satellite-Based Doppler Lidars Multiple Doppler Lidars One fixed Two independently mobile Dual Polarization Multiple Doppler Radars One fixed Multiple independently mobile includes clear air coverage with/without insect tracers complementary coverage with clouds Advanced Regional Model Assimilation of satellite-based surface energetics Improves high-resolution models for SEUS & north Alabama Setting Moderately complex terrain (orography and land usage) Some instruments operate for intensives Some instruments operate 24/7
