  3. ACC Portal Overview

  4. Status & progress on GEO 2009-2011 Task: ACC Portal • This task seeks to develop a VC portal for Atmospheric Composition Constellation (ACC). • Identify requirements and implement a prototype ACC portal for evaluation and eventual use by the ACC, GEOSS and other AC user communities. • Other AC and Air Quality portals exist; this task seeks to identify the unique requirements and common (shared) features of the ACC / GEOSS users to provide a value-added and complementary capability. • The CEOS ACC group is guiding the requirements and goals for this task. • DLR and NASA are working on implementation plans for the initial ACC Portal. • Other ACC member agencies are invited in the co-ordination of portal evaluation activities and the provision of portal data and tools.

  5. Status & progress on GEO 2009-2011 Task: DLR-NASA Coordination • Initial coordination among CEOSS ACC Group, DLR and NASA • February meeting in Oberpfaffenhofen, Germany (DLR) • Drafted ACC Portal mission • Drafted architectural approach • Decided to initiate portal development with WDC-RSAT, Giovanni, and DataFed • Follow-up telecons • Formation of technical team to outline implementation approach

  6. ACC PortalMission Statement Provide access, tools, and contextual guidance to scientists and value-adding organizations in using remotely sensed atmospheric composition data, information, and services. The ACC Portal will help to foster interoperability and application of atmospheric composition data, information and services worldwide.

  7. Approach • Use WDC-RSAT as ACC portal foundation • Enhance with Giovanni and DataFed • Coordinate with CEOS ACC Group to define and refine requirements • Take inventory of existing and planned portals, tools, services and architectures • identify gaps, unique value-added by an ACC Portal, and capabilities shared with other efforts • Define an initial architecture • Define demonstration pilot to be developed in phases • Use regular telecons and a collaboration website to coordinate • Connect with ESIP, Application Sciences, and other related efforts • Work with CEOS ACC Group to create a user advisory board

  8. Defining ACC Portal Users • Atmospheric Science Researchers • Value-adding organizations • Organizations that process (aggregate, filter, combine or analyze) remote sensing data for particular applications and users Users can be characterized by their: Domain Groups Air Quality Climate Stratospheric Ozone Data Needs Real-time Forecast Archived data Contextual Needs • Processes used, assumptions made in deriving AC data products • Understanding of AC data products for application in their domain • Availability of data products • Previous uses of the AC data products

  10. Desirable ACC Portal Features • Interoperable web services – Use of standards-based interfaces to share data, services and tools from WDC-RSAT, BEAT/VISAN, Giovanni, DataFed and other related AC service providers, including support of distributed • Data Access – Spatial, temporal and other queries to AC data returning data in multiple, standard formats • Visualization – Provide completed visualization results and access to tools to conduct visualization • Processing & Analysis – Provide completed data processing and data analysis results and access to tools to conduct processing and analysis • Contribution to GEOSS(Architecture Implementation Pilot) – Become a community ‘node’ in the GEOSS Architecture by serving as an • AC Community Catalog - Data providers can register their services with the AC Community Catalog. The AC Community Catalog, in turn, is registered with the GEO Registry via a standard catalog interface, thereby allowing the GEOSS Clearinghouses to harvest metadata for the individual AC services • AC Community Portal - Users can search the metadata in the GEOSS Clearinghouses with AC-focused queries to discover relevant data and tools • User contributed content – Use of social networking and knowledge networking (e.g., wikis, blogs, forums, keyword tagging, interoperable portlets, RSS feeds, etc) that allow AC users to provide feedback and input to the AC Portal. Examples might include users • sharingpublications in which they have used AC data • posting questions on assumptions made in the derivation of AC data products • identifying unique AC data needs for a particular application • custom configuring the portal front-end using portlets for their particular scientific or application areas

  12. Potential view of future ACC Portal

  13. ACC PortalMilestones (tentative) • Initial ACC portal objectives & design By 15 May 2009 • DLR/NASA AC tools evaluation and technical assessment By 1 July 2009 • ACC portal prototype By 15 Sep 2009 • Demonstrate to GEO-VI, Wash. DC By 18 Nov 2009 • Plans for portal governance/maintenance By 31 Dec 2009

  14. Participants in initial design & approach • DLR • Michael Bittner • Diego Loyla • Beate Hildenbrand • Kathrin Höppner • Volker Mohnen • NASA • Ernie Hilsenrath • Karen Moe • Frank Lindsay • Greg Leptoukh • Stefan Falke (Northrop Grumman) • ESA • Claus Zehner

  15. Task Revisions • Added Michael Bittner (DLR) as POC • Added ‘AC tools evaluation‘ task

  16. NASA Perspective & Status

  17. NASA Contributions to ACC Portal • Active participation in ACC Portal design and implementation • Contributing to ACC Portal architecture • Integration of Existing Systems • Giovanni • DataFed • Hosting collaboration website • Hosting coordination telecons

  18. GES-DISC Interactive OnlineVisualizationANdaNalysis Infrastructure (Giovanni) • With Giovanni and a few mouse clicks, one can easily obtain information on the atmosphere around the world. • There is need to learn data formats to retrieve and process data. • You can try various combinations of parameters measured by different instruments. • All the statistical analysis is done via a regular web browser. • http://giovanni.gsfc.nasa.gov/ • Caution: Giovanni is a constantly evolving data exploration tool!

  20. Five practices for agile, seamless data federation: DataFed: A web infrastructure for sharing and analyzing air quality data • Space-Time Query for standardized access to all data (WCS) • Data Wrappers for turning heterogeneous data into web services • Data Mediators for transforming data into ‘Views’ • Mashups for connecting autonomous application • DataSpaces for shared metadata by the users, for the users Rudolf Husar (rhusar@me.wustl.edu ) http://www.datafed.net
