1 Earth-Sun System Division National Aeronautics and Space Administration SPoRT SAC Nov 21-22, 2005 NSSTC ARMOR Dual-Polarimetric Doppler Radar: A Supporting Resource for SPoRT Dr. Walt Petersen ESSC/NSSTC/UAH November 21, 2005 ARMOR: Advanced Radar for Meteorological and Operational Research C-band Upgrade to dual-polarimetry and solid state transmitter ; finished 3/05 Control from NSSTC (data archived here also) Real time data to NWS and Web Flexible/adaptable tool for interrogation and research of Cloud Physics and ABL within the greater context of SPoRT objectives [SUPPORTING TOOL]

2 Earth-Sun System Division National Aeronautics and Space Administration SPoRT SAC Nov 21-22, 2005 ARMOR “Boiling Pot”: Convective Initiation Applications Improved threat detection CI detection, short- term forecast WRF Validation/DA CI CP CBL Tools ARMOR (Flexible high resolution scanning) LMA/NLDN SATELLITE

3 Earth-Sun System Division National Aeronautics and Space Administration SPoRT SAC Nov 21-22, 2005 Severe Storms: ARMOR February 21 2005 3-D Dynamics/Microphysics Lightning Processes: Tools: ARMOR, NEXRAD, LMA Model Validation, DA Satellite Validation Warning Decision 6.0 km CAPPI dBZ 2.0 km CAPPI dBZ ARMOR HID X-Z Cross Section Y=-18 km Height (km) X (km) Sources “cap” the most intense core at top of updraft column and in graupel/small hail (not large hail). -10 -40 What does lightning data characterize?

4 Earth-Sun System Division National Aeronautics and Space Administration SPoRT SAC Nov 21-22, 2005 E.g., 21 Feb. 2005 Convection from NASA TRMM Satellite TRMM-PR TMI 85 GHz VIRS IR Extension to Space and Model DA What is there? What can be assimilated? GLMGPM + Present/Future satellite precipitation retrievals PMW (also model-based) The future PMW + IR + Lightning? Virtual Radar? e.g. Lightning flash rate DA

5 Earth-Sun System Division National Aeronautics and Space Administration SPoRT SAC Nov 21-22, 2005 GLOBAL TRMM REGIONAL SCALE HOUSTON Incorporation of Lightning into Models: ICE! STORM SCALE ARMOR-LMA Physical basis for improved forecasts IC flash rate controlled by graupel (ice mass) production (and vertical velocity) Observational Validation: IWP  Flash Density Global to Cloud Scale Use in WRF? (ice is a prognostic) Ice mass Flash Rate Cloud Model
