Abstract:
From natural disasters such as flooding and forest fires to
man-made disasters such as toxic gas releases, the impact of weather-influenced
severe events on society can be profound. Understanding, predicting, and
mitigating such local, mesoscale events calls for a cyberinfrastructure
to integrate multidisciplinary data, tools, and services as well as the
capability to generate and use high resolution data (such as wind and
precipitation) from localized models. The need for such end to end systems --
including data collection, distribution, integration, assimilation,
regionalized mesoscale modeling, analysis, and
visualization -- has been realized to some extent in many academic and
quasi-operational environments, especially for atmospheric sciences data. However, many challenges still remain in the
integration and synthesis of data from multiple sources and the development of
interoperable data systems and services across those disciplines.
Over the years, the Unidata Program
Center has developed several tools
that have either directly or indirectly facilitated
these local modeling activities. For
example, the community is using Unidata technologies
such as the Internet Data Distribution (IDD) system, Local Data Manger (LDM), decoders,
netCDF libraries, Thematic Realtime
Environmental Distributed Data Services (THREDDS), and the Integrated Data
Viewer (IDV) in their real-time prediction efforts. In essence, these technologies for data
reception and processing, local and remote access, cataloging, and analysis and
visualization coupled with technologies from others in the community are becoming
the foundation of a cyberinfrastructure to support an
end-to-end regional forecasting system.
To build on these capabilities, the Unidata Program
Center is pleased to be a
significant contributor to the Linked Environments for Atmospheric Discovery (LEAD)
project, a NSF-funded multi-institutional large Information Technology Research
effort. The goal of LEAD is to create an integrated and scalable framework for
identifying, accessing, preparing, assimilating, predicting, managing,
analyzing, mining, and visualizing a broad array of meteorological data and
model output, independent of format and physical location. To that end, LEAD
will create a series of interconnected, heterogeneous Grid environments to
provide a complete framework for mesoscale research,
including a set of integrated Grid and Web Services.
This talk will focus on the transition from today’s
end-to-end systems into the types of systems that the LEAD project envisions
and the multidisciplinary research problems they will enable.
