  • Atmospheric Composition Portal BackgroundThe Atmospheric Composition Constellation (ACC) and the Workgroup for Information Systems and Services (WGISS) within the Committee on Earth Observation Satellites (CEOS) is developing a portal to support interoperability among the atmospheric composition research and applications communities.The portal was called for by CEOS as part of the sanctioned constellations and is a GEO taskA need was perceived to develop a shared collaboration place for remotely sensed atmospheric composition related data and informationThe aim is to enhance international cooperation, data sharing and servicesThe technical challenge is to explore how disparate systems across agencies and countries can work together more seamlessly.*

  • *AC PortalMission Statement

    Provide access, tools, and contextual guidance to scientists and value-adding organizations in using remotely sensed atmospheric composition data, information, and services.

    Help foster interoperability and application of atmospheric composition data, information and services worldwide.

    Identify the unique requirements and common (shared) features of the ACC and GEOSS users to provide a value-added and complementary capability.

    Work with partners in CEOS and the broader AC community in advancing the AC Portal

  • Anticipated Features of the AC Portal *

  • *= connectivity between portal contributors

  • *Anticipated AC Portal UsersAtmospheric Science Researchers

    Value-adding organizationsProcess (aggregate, filter, combine or analyze) remote sensing dataDevelop decision support tools or particular applications and users

    Users can be characterized by their:Domain Groups: Air Quality, Climate, Stratospheric Ozone

    Data Needs: Near-real-time, Forecast, Archived dataInformation Context Needs Processes used, assumptions made in deriving AC data products Understanding applicability of AC data products in their domain Availability of data products Previous uses of AC data products

    Initial effort focused on:Collaboratively creating a web application within WDC-RSAT for comparison of satellite derived atmospheric composition datasets accessed from distributed data sourcesImplementation of data access and interoperability standardsSolicit feedback from potential users and other participantsEspecially others in WGISS DataOzone (now)NO2 (coming soon)

  • AC Portal Alpha ReleaseAnnouncement*The CEOS WGISS Atmospheric Composition Interest Group announces the alpha release of the Atmospheric Composition Portal (AC Portal). The AC Portal is being developed to: provide access, tools, and contextual guidance to scientists and value-adding organizations in using remotely sensed atmospheric composition data, information, and services. foster interoperability and application of atmospheric composition data, information and services worldwide. identify unique requirements and common (shared) features of the ACC and GEOSS users to provide a value-added and complementary capability. collaborate with partners in CEOS and the broader AC community in advancing the objectives of the AC Portal. The alpha release represents an initial version of the AC Portal intended to generate ideas and feedback, and to invite others to become involved in the AC Portal development. A beta release is planned for 31 August 2010. AC Portal: About the AC Portal: What's Next for the AC Portal: Provide your ideas, interests and comments: To stay updated on the latest AC Portal developments, please subscribe to the AC Portal announcements email list by sending an email to [email protected] with subject heading 'AC Portal announcements'.

  • Participation from broader WGISS and CEOS communityWe seek your recommendations in developing the AC Portal what would be useful from your perspective?

    Data ProvidersWhat is important for users of your data to know when applying it to air quality or climate applications?What kind of information would you like to get from users of your data?Data UsersDo you have unmet or challenging remotely sensed AC data needs?Any issues you encounter in working with remotely sensed AC data?Do you need any processing, analysis, visualization tools to supplement your existing tools?Would visualization and analysis tools in an online environment be useful?Do you work with metadata?

    For more information and provide feedback and comments:

  • GEO-CEOS Task AR-09-02a _30IN PROGRESS: The AC Portal Technical Team announced the AC Portal alpha release on 18 May 2010 at WGISS 29. We are participating in the GEOSS Architecture Implementation Pilot, Phase 3 that kicked-off in March 2010, where we plan to contribute AC data web services, and to provide input on the structure of metadata and the process for registering services in the GEOSS Common Infrastructure. COMPLETED: The AC portal provides access, tools and guidance to atmospheric scientists and the value-added organizations in using remote EO in Atmospheric Composition data, information and services. The portal was presented and demonstrated at the following meetings: 1) ACC Workshop on Air Quality in Frascati, Italy on 15 June, 2009, 2) GEO-VI Plenary and Air Quality meetings in Washington DC on 17 Nov, 2009, 3) ESIP Winter Meeting in Washington DC 5 Jan, 2010, 4) ACC Workshop in Montreal 30-31 March where a progress report and demo were presented and several pilot uses of the portal identified. *
