Linked Environments forAtmospheric Discovery

Transforming the sensing and numerical prediction of high impact local weather through dynamic adaptation

Vision

Revolutionize the ability of scientists, students, and operational practitioners to observe, analyze, predict, understand, and respond to hazardous or severe weather by interacting with it dynamically and adaptively

Motivation

  • Weather technologies are hard to use in sophisticated ways because they’re complicated and linked together using cumbersome software - creating aHUGE DIVIDE BETWEEN THE HAVES AND THE HAVE NOTS

  • High impact local weather isVERY DYNAMICwhile our tools, cyber environments and learning modalities are highlySTATIC

GOALS

  • #1: Lowering the barrier for using complex end-to-end weather technologies

    • Democratize the availability of advanced weather technologies for research and education

    • Empower application in a grid context

    • Facilitate rapid understanding, experiment design and execution

  • #2: Dynamic Adaptation to Weather

    • Models and hazardous weather detection systems responding to observations and their own output

    • Models and hazardous weather detection systems driving the collection of observations

    • IT infrastructures providing on-demand, fault tolerant services

What can LEAD do for you?

  • Researchers

    • Access to: Powerful tools for Assimilation, Prediction, Mining and Visualization

    • Supercomputing resources - TeraGrid

    • Data – real-time and recent data resources

  • Educators

    • Access to: LEAD Learning Communities – tools and colleagues

    • Classroom demonstrations – hands on access to tools

    • Data –real-time and recent data resources

  • Students

    • Access to: Resources to learn about and visualize the weather

    • With approval – create experiments access tools

    • Data –real-time and recent data resources

How? : Built on (Web) Services

[But in a Grid Framework]

3

Service A

(Forecast Model)

Service B

(Terrain Preprocessor)

Service C

(Interpolator Service)

Many others…

How? : Workflow Generation

4

Pre-configured workflows automatically generated, which can be modified by users via a composition tool – launch manually or via trigger (dynamic)
