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

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

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  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. Some Examples of ARM Quicklook IOPshare 2D-S Products

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

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

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

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

13  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. 2D-S Archive Data
