AB: DataFed is a distributed web-services-based computing environment for accessing, processing and rendering environmental data in support of air quality management and science. The flexible, adoptive environment facilitates the access and flow of atmospheric data from provider to users by enabling the creation of user-driven data processing value chains. The approach of DataFed is mediation between users and data providers. DataFed assumes the autonomous and spontaneous emergence of distributed data sources. It non-intrusively wraps datasets for access by web services. The mediator software, composed of web services, provides homogeneous data views (e.g. geospatial, time views) using a global multi-dimensional data model. Application software written using web services consists of data browsers and analysis tools for distributed AQ data. Currently DataFed serves as data gateway for user programs; web pages, GIS, science tools as well as for loosely coupled Service Oriented Architecture Applications. Its federated data pool consists of over 50 datasets and the tools have been applied in several air pollution projects.
