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

Future Integrated AQ information System (Draft for Feedback)

Data are maintained by custodians and exposed through ‘portals’

Mediators uniformly ‘wrap’ data and provide processing services

Analysts program the services to create application-specific products

Responsibility is shared among data providers and mediator/ integrators

ESIPFed can provide the infrastructure and tools for the AQ info system

DataFed Description

DataFed Vision

Better air quality management and science through by effective use of relevant data

DataFed Goals

Facilitate the access and flow of atmospheric data from provider to users

Support the development of user-driven data processing value chains

P articipate in specific application projects

Approach: Mediation Between Users and Data Providers

DataFed assumes spontaneous, autonomous emergence of AQ data ( a la Internet)

Non-intrusively wraps datasets for access by web services

WS-based mediators provide homogeneous data views e.g. geo-spatial, time...

End-user programming of data access and processing through WS composition (limited)

Applications

Building browsers and analysis tools for distributed monitoring data

Serve as data gateway for user programs; web pages, GIS, science tools

DataFed is currently focused on the mediation of air quality data

Anatomy of a Wrapper Service: TOMS Satellite Image Data

Given the URL template and the image description, the wrapper service can access the image for any day, any spatial subset using a HTTP URL or SOAP protocol:

Wrapper classes are available for geo-spatial (incl. satellite) images, SQL servers, text files,etc. The mediator classes are implemented as web services for uniform data access, transformation and portrayal.

Datasets Used in FASTNET

Data are accessed from autonomous, distributed providers

DataFed ‘wrappers’ provide uniform geo-time referencing

Tools allow space/time overlay, comparisons and fusion
