2. Goals of LEAD Day Introduce LEAD concepts and software to you Get feedback from you

3. LEAD Goal: Democratization Making it EASY for users to: – experiment using meteorological tools – create meteorological forecasts – perform mesoscale modeling and forecasting – access data (source and product) – make use of large scale cyberinfrastructure (teragrid)

4. This means: Freedom from Technological Issues* Hassle free access to supercomputing resources –TeraGrid, mass storage devices Hassle free execution of forecast models and related tools –WRF –ADAS, WRFSI, … Data format independence * If you’d lived through what we’ve gone through you’d really appreciate what this means!!

5. Two LEAD Orchestration Systems LEAD Portal –Web based portal/portlets –Web Service based orchestration –Thin client (browser) –ADAS for initial and boundary conditions Siege Ensemble Broker –Desktop client based –Web Service based orchestration –Thick client (Siege and IDV) –WRFSI for initial and boundary conditions

6. Logistics AM: Two groups (blue, green) –1 st hour: Explore each system, launch a run, evaluate 1) LEAD Portal 2) Siege –2 nd hour: Rich: LEAD in Education PM: one large group –View results, compare with radar data, discussion, final evaluation

7. Caveat This is the bleeding edge!!! “Winging it”: “This expression comes from the theater, where it alludes to an actor studying his part in the wings (the areas to either side of the stage) because he has been suddenly called on to replace another.”
