8. Observations ~ 30˚

9. Observations cont… Google Earth

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). 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.
