Outline

Atmospheric Composition Portal Background

The 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 task

A need was perceived to develop a shared collaboration place for remotely sensed atmospheric composition related data and information

The aim is to enhance international cooperation, data sharing and services

The 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

Initial CapabilityDemonstration

Goal: Demonstrate the feasibility of connecting distributed atmospheric composition data and analysis tools into a common and shared web framework

Initial effort focused on:

• Collaboratively creating a web application within WDC-RSAT for comparison of satellite derived atmospheric composition datasets accessed from distributed data sources

• Implementation of data access and interoperability standards

• Solicit feedback from potential users and other participants

• Especially others in WGISS

• Data

• Ozone (now)

• NO2 (coming soon…)

AC Portal Alpha ReleaseAnnouncement

13

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.

Participation from broader WGISS and CEOS community

We seek your recommendations in developing the AC Portal – what would be useful from your perspective?

• Data Providers• What 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 Users• Do 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: • http://wgiss-acig.wustl.edu

GEO-CEOS Task AR-09-02a _30

IN 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 usingremote 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.
