  1. PR-2 Radar in Aguadilla Ricardo Ríos Olmo Advisor: Dr. José Colom

  2. Outline • Objective • About PR-2 • PR-2 vs Nexrad • Observations • Recent Ideas • Next Up….

  3. Objective • Modify Source Code to our needs: • Raw Data • Display Resolution • Data Resolution • Data Transfer from Aguadilla – UPRM • Validate Radar Data • Pulse width modification??

  4. About PR-2 Radar donated by EWR Weather Radar Systems. Model: EWR 600 System Specifications • Tx/Rx • Frequency: 9.345 GHz (± 30 MHz) • Power Output: 4kW peak • Pulse Width: 4µs • Range: 40Nm (for our purposes) • PRF: 119 Hz (± 10 %) • Receiver Gain: 135dB • Antenna • Flat Plate (Slotted Waveguide) • Size : 18” • HPBW: 5.5˚ • Gain: 31.0 dB • Side Lobes : -25 dB • Tilt: 0˚ to 15˚

  5. Location Coordinates: 18°28'30.30"N 67° 7'13.81“W Total radar height in site: 50ft

  6. Radar Data Interface

  7. PR-2 vs Nexrad Comparison • Data Comparison: EWR vs Nexrad

  8. Observations ~ 30˚

  9. Observations cont… Google Earth NOAA Provides Magnetic Declination Calculator: 12˚ W from MN 12˚

  10. Observations cont… Nexrad starts plotting @ ~ 0dBz vs EWR @ 23dBz. Missing Light Rain?

  11. Recent Ideas • Looking into modifying the transmitted pulse width. • Benefits: • Gain coverage within Aguadilla. • Ease the possibility of an external calibration (if in need).

  12. Next Up… • Modify EWR Source Code. • Establish DSL – File Transfer to UPRM. • Check for installation errors. • ** Modify pulse modulation for better coverage. Crucial Needs… • EWR Source Code • Update: EWR Agreed to give us code. It’s in due process.
