  1. 2D-S Participation in RACORO Brad Baker, Paul Lawson and Qixu Mo

  2. Outline • 2D-S Features • Examples of Quicklook IOPshare 2D-S Products • Data Place in Final Archives.

  3. Custom 128-photodiode array/front end with ~ 10 times the response speed of older probes (smaller 50 m pixels on the array). • 10 m particles imaged at 170 m s-1 (front end up to 233 m s-1) • Two independent imaging probes in one instrument provide stereo images of some particles and measurement redundancy • Large Sample Volume: 3 times the 2D-C Sample Volume

  4. Example Showing how 2D-S Particle Inter-arrival Times are used to Remove Shattered (and Splashed) Images

  5. Example of Correcting out-of-focus “Donuts”

  6. Some Examples of ARM Quicklook IOPshare 2D-S Products • Comparison of 2D-S, CAS and CIP PSD’s • Time Series and Scatterplot Comparisons of 2D-S H and V channels • Time Series and Scatterplot Comparisons of 2D-S from 10 to 50 m with CAS from 9 to 50 m • Time Series and Scatterplot Comparisons of 2D-S > 50 m with CIP > 50 m.

  7. Comparison ofPSD’s: CAS,CIP, 2D-S (V) , 2D-S (H)

  8. Time Series Comparison:CAS 9 to 50 m 2D-S (V) 10 to 50 m 2D-S (H) 10 to 50 m

  9. Comparison of 2D-S (V) and 2D-S (H) Channels

  10. Scatterplot Comparison: 2D-S (V) 10 to 50 m CAS 9 to 50 m

  11. Time Series Comparison:CIP > 50 m 2D-S (V) > 50 m 2D-S (H) > 50 m

  12. Scatterplot Comparison: 2D-S (V) > 50 m CIP > 50 m

  13. 2D-S Archive Data • 1-Hz PSD’s of Concentration, Area and Mass with Splashers Removed and “Donuts” Resized • 1-Hz Total Particle Concentration, Extinction, LWC, Effective Radius, Radar Reflectivity • 2D-S Images: All Images Archived.
