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]

ARMOR “Boiling Pot”: Convective Initiation

  • Tools
    • ARMOR (Flexible high resolution scanning)
    • LMA/NLDN
    • SATELLITE
  • Applications
    • Improved threat detection
    • CI detection, short-term forecast
    • WRF Validation/DA

Extension to Space and Model DA

What is there? What can be assimilated?

GLM

The future

GPM

VIRS IR

TMI 85 GHz

TRMM-PR

E.g., 21 Feb. 2005 Convection from NASA TRMM Satellite

e.g. Lightning flash rate DA

Present/Future satellite precipitation retrievals PMW (also model-based)

PMW + IR + Lightning?

Virtual Radar?

Incorporation of Lightning into Models: ICE!

Physical basis for improved forecasts

IC flash rate controlled by graupel (ice mass) production (and vertical velocity)

Flash Rate

  • Observational Validation:
    • IWP  Flash Density
    • Global to Cloud Scale
  • Use in WRF? (ice is a prognostic)

Ice mass
