1 Rain Rates Measured Acoustically Using Passive Aquatic Listener Jie Yang, William E. Asher, Jeffrey A. Nystuen, and Andrew T. Jessup Applied Physics Laboratory, University of Washington Acoustics Department talk, April 7, 2014

2 Argo floats (collaboration with Steve Riser) Park depth – 1000 m Profile duration – several days several years Expected lifetime – several years Iridium communication – 2-way PAL for moorings Adaptive underwater recorder Very low power consumption High bandwidth (1-40 kHz) Park depth – 2000 m

3 TropicalPacific TropicalPacific Float #6917 4/2011 – 3/2012 3

4 Float trajectories during SPURS (Thanks to Jessica Anderson for the figure) 200 km 220 km Float 7587

5 Comparison of wind speed between PAL and central mooring Float 7587

6 Comparison of accumulated rain amount Float 6923 Float 7681 Float 7587

7 Passive acoustic monitoring of the ocean can provide measurements of wind speed and rainfall rate Passive acoustic monitoring technology has been deployed on STS/PAL floats Initial results from five STS/PAL floats (SPURS region, Equatorial Pacific, and Bay of Bengal) show wind speed and rainfall climatology Acoustically derived wind speed compares very well with central mooring MET data Comparison between acoustically derived rainfall accumulation using the twelve SPURS STS/PAL floats with satellite data is very encouraging Summary
