Horrigan, Associate Director http://www.pewinternet.org/pdfs/PIP_Exploratorium_Science.pdf NSF (my sponsor) has long recognized the importance of science and technology interactions:  NSF (my sponsor) has long recognized the importance of science and technology interactions Nancy Wilkins-Diehr ([email protected]) NSF Continues Its Leadership Today What Will Lead to Transformative Science?:  NSF Continues Its Leadership Today What Will Lead to Transformative Science? Nancy Wilkins-Diehr ([email protected]) Gateways are a terrific example of interfaces that can support transformative science Flagship US$52M CDI Program Launched in 2008:  Flagship US$52M CDI Program Launched in 2008 Nancy Wilkins-Diehr ([email protected]) Don’t use:  Don’t use Nancy Wilkins-Diehr ([email protected]) Three Thematic Areas Offer Diversity:  Three Thematic Areas Offer Diversity Nancy Wilkins-Diehr ([email protected]) Exciting Canadian Activities:  Exciting Canadian Activities Nancy Wilkins-Diehr ([email protected]) Science Gateways are a Natural Extension of Internet Developments:  Science Gateways are a Natural Extension of Internet Developments Nancy Wilkins-Diehr ([email protected]) Gateway Idea Resonates with Scientists:  Gateway Idea Resonates with Scientists Capabilities provided by the Web are easy to envision because we use them in every day life Researchers can imagine scientific capabilities provided through a familiar interface Groups resonate with the fact that gateways are designed by communities and provide interfaces understood by those communities But also provide access to greater capabilities on the back end without the user needing to understand the details of those capabilities Scientists know they can undertake more complex analyses and that’s all they want to focus on But this seamless access doesn’t come for free. It all hinges on very capable developers Nancy Wilkins-Diehr ([email protected]) Trust and Reliability are Fundamental to Success:  Trust and Reliability are Fundamental to Success Nancy Wilkins-Diehr ([email protected]) How can we build interfaces that scientists will trust?:  How can we build interfaces that scientists will trust? Expertise Simple web pages are easy to design Complex capabilities, particularly those involving grid access, take knowledgeable developers to create a production product LEAD, nanoHUB show what investment can do Sustained funding Most science groups have money for research, not portal building or ongoing support for portals Knowledge transfer Must take advantage of industry advancements Investments must result in building blocks that other applications can use Many gateways have similar issues Data access Analysis capabilities User work environments Workflow capabilities Nancy Wilkins-Diehr ([email protected]) Tremendous Opportunities Using the Largest Shared Resources - Challenges too!:  Tremendous Opportunities Using the Largest Shared Resources - Challenges too! What’s different when the resource doesn’t belong just to me? Resource discovery Accounting Security Proposal-based requests for resources (peer-reviewed access) Code scaling and performance numbers Justification of resources Gateway citations Tremendous benefits at the high end, but even more work for the developers Potential impact on science is huge Small number of developers can impact thousands of scientists But need a way to train and fund those developers and provide them with appropriate tools Nancy Wilkins-Diehr ([email protected]) What is the TeraGrid? A unique combination of fundamental CI components:  What is the TeraGrid? A unique combination of fundamental CI components What is the TeraGrid?:  What is the TeraGrid?

It's interesting that I found an example using IDV that parallels our discussion of mesoscale boundaries in class. It illustrates very nicely the transition to a coastal low and the strong baroclinic zone with a location very similar to Markowski's depiction. I created this image in IDV after running a 5-km WRF run (initialized with NAM output) via the LEAD Portal. This simple 1-level plot is just a precursor of the many capabilities IDV will eventually offer to visualize high-res WRF output. Enjoy!
