Presentation Transcript

    1. Processing Airborne Doppler Radar Data

    3. Raw unedited data

    4. Radial velocity corrected for aircraft speed

    5. Remove bad data in rings

    6. Remove bad data in rings

    7. Removing signals with low Normalized Coherent Power

    8. Data with low coherent power removed

    9. Lone data points deleted – “despeckling”

    10. Most of ground clutter removed

    11. Manually removing bad data

    12. Most bad data manually removed

    13. Data that varies significantly from neighboring data removed – “defreckling”

    14. Final clean edited radar sweep!

    15. Next step? Repeat the process about 240 times for a 10 minute Quad-Doppler leg!

    16. How Quad Doppler wind retrieval from airborne radars works

    17. How Quad Doppler wind retrieval from airborne radars works

    18. How Quad Doppler wind retrieval from airborne radars works

    19. How Quad Doppler wind retrieval from airborne radars works

    20. What’s next? Choose several different parameters How to calculate vertical motion (more later) How much smoothing to do (more later) How to take out the terminal fall speed of precipitation particles Many others

    21. Wind Output @ 3.5 km

    22. Vertical cross-section

    23. Vertical cross-section

    24. Vertical cross-section

    25. Choosing a ‘w’ calculation method

    26. Choosing the amount of smoothing
