PR-2 vs Nexrad Comparison • Data Comparison: EWR vs Nexrad
Observations ~ 30˚
Observations cont… Google Earth NOAA Provides Magnetic Declination Calculator: 12˚ W from MN 12˚
Observations cont… Nexrad starts plotting @ ~ 0dBz vs EWR @ 23dBz. Missing Light Rain?
Recent Ideas • Looking into modifying the transmitted pulse width. • Benefits: • Gain coverage within Aguadilla. • Ease the possibility of an external calibration (if in need).
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.
