DRAFT April 28, 2005 ESIP AQ Cluster, [email protected]Current Air Quality Information ‘Ecosystem’ (Draft for Feedback) AQ information includes emissions, ambient & satellite data and model outputs The distributed data are produced and provided by agencies, mostly through portals Providers have different access protocols, formats, and information usage conditions This lack of interoperability causes the under-utilization of the rich data resources

• AQ information includes emissions, ambient (surface) and satellite data and model outputs • The information is provided by multiple Agencies, have different form and is• AQ data usage requires considerable processing and integrating

• Data transport is being actively pursued: OPeNDAP, SOAP, ...
• Earth System Partners need to be able to find and use various data sets, wherever they may be, whatever format...
• THREDDS can provide dynamic access and generate catalogs
• GCMD is a major resource for metadata management for the entire GeoSciences community- this activity must evolve!
• Ontology projects such as SWEET in conjunction with THREDDS and GCMD can provide individual data sources, data variables and metadata management for the community.

• Traditional Unidata Approach– Mainly meteorological data– Subscription system pushes data to user sites– Unidata Program Center provides data analysis tools for
use on data at user sites
• THREDDS Enhancements– Broader menu of Earth system data– Local client access from remote servers– Less arcane, more general and accessible tools– Integration of data and analysis tools into educational
modules and digital libraries
THREEDS
The THREDDS (Thematic Realtime Environmental Distributed Data Services) project is developing middleware to bridge the gap between data providers and data users. The goal is to simplify the discovery and use of scientific data and to allow scientific publications and educational materials to reference scientific data.
The mission of THREDDS is for students, educators and researchers to publish, contribute, find, and interact with data relating to the Earth system in a convenient, effective, and integrated fashion. Just as the World Wide Web and digital-library technologies have simplified the process of publishing and accessing multimedia documents, THREDDS is building infrastructure needed for publishing and accessing scientific data in a similarly convenient fashion.
• Universities have used Unidata tools to acquire, analyze, and display real-time atmospheric data for nearly 20 years
• THREDDS – along with related client/server access and display technologies-- makes an even broader menu of Earth system data to a more diverse community of users
• THREDDS technologies enable the creation of compound educational modules and scientific publications with embedded pointers to datasets and tools.
