1 Sponsored by the National Science Foundation GENI Alpha Demonstration Nowcasting: UMass/CASA Weather Radar Demonstration David Irwin November 3,

2 Sponsored by the National Science Foundation 2 November 3, 2010 Problem CASA (an NSF ERC) is studying experimental networks of small controllable weather radars –Better data is the foundation of better hazardous weather detection and earlier warnings –Complex modeling to detect inclement weather requires many resources: sensors, bandwidth, storage, and computation Costly to dedicate resources for rare events –How do we generate accurate, short-term “nowcasts” using these new distributed radar systems?

3 Sponsored by the National Science Foundation 3 November 3, 2010 Solution Today: only a few large NEXRAD radars (100s) Tomorrow: many (1000s) smaller, less expensive radars produce data close to the ground where weather happens Requires a flexible infrastructure for coordinated provisioning of shared sensing, networking, storage, and computing resources on-demand

4 Sponsored by the National Science Foundation 4 November 3, 2010 Example: Puerto Rico Testbed UPRM Student Testbed –Led by Jorge Trabal, Prof. Sandra Cruz-Pol, and Prof. Jose Colom –http://www.youtube.com/watch?v=7TR64BhwMlIhttp://www.youtube.com/watch?v=7TR64BhwMlI

5 Sponsored by the National Science Foundation 5 November 3, 2010 Demo Background Dynamic end-to-end Nowcasting on GENI –Use GENI/Orca Control Framework (RENCI/Duke) https://geni-orca.renci.org/trac/ –Reserve heterogeneous slice of resources Sensing Slice: UMass ViSE radars Networking Slice: NLR, BEN-RENCI Computation Slice: Amazon EC2 + UMass and RENCI VMs Storage Slice: Amazon S3

Chandrasekar –Nowcasting Software RENCI/Duke –Orca Control Framework –BEN network Starlight

9 Sponsored by the National Science Foundation 9 November 3, 2010 Conclusion GENI is critical for next-generation applications –Enable nowcasting in experimental radar systems –GENI capabilities: “sliceability”/virtualization, federation, network programmability Provide domain scientists a new platform –Experiment with tightly integrated systems combining sensing, storage, networking, computing –Engage domain scientists in CASA and elsewhere Extend GENI network to Puerto Rico
