ARMOR is a scanning dual-polarimetric Doppler radar operating at C-band (5625 MHz) with a beam width of 1o. It was originally deployed in Huntsville by the National Weather Service as a local warning radar in 1977 (WSR-74C), refurbished and upgraded to Doppler in 1991. The radar was donated to the UAH Dept. of Atmospheric Science in 2002 and upgraded to dual-polarimetry using the SIGMET Antenna Mounted Receiver in Fall 2004.

ARMOR Dual-Polarimetric Doppler Radar
Paving the Way for Scientific Advancement

Education and training
     - UAH graduate students will gain experience using an advanced
       polarimetric radar platform in advance of the National Weather
       Service NEXRAD network upgrade.
     - Real-time student use of the radar in both classroom and
       research environments

Continuous data archive at NSSTC for full volumetric and surveillance scans

One of a kind technology transfer via real-time use of ARMOR in the broadcast meteorology domain.

Real-time operational feed to NWS for nowcasting and training at NWS WFO Huntsville

Supports basic thunderstorm, cloud physics, cloud electrification and precipitation research within the UAH/NASA Severe Thunderstorm Observations and Research Meteorological NETwork (STORM-NET)

    - Strategically located with UAH Mobile Integrated Profiling
      System (MIPS) and

Source for Satellite precipitation mission ground truth and physical validation via precipitation microphysics retrieval and kinematic measurements (dual-Doppler)

Vastly improved Quantitative Precipitation Estimation (QPE) for surface hydrological and water cycle studies

Operational meteorological decision support tool development and data assimilation (e.g. NASA-SPoRT)

Detailed cloud kinematic, microphysical, electrification, and lightning studies using the NASA Northern Alabama Lightning Mapping Array (NASA-MSFC/NSSTC Thunderstorm and Lightning Group) , ARMOR polarimetric variables and real-time dual-Doppler capability.

Potential hydrological data input for assimilation into local distributed runoff models, regional flood plain studies/planning

Near surface wind retrievals for assimilation into pollutant dispersion models

Boundary layer studies including identification of biological flyers
