Acc portal overview

ACC Portal Overview


Status progress on geo 2009 2011 task acc portal

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.


Status progress on geo 2009 2011 task dlr nasa coordination

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


Acc portal mission statement

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.


Approach

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


Defining acc portal users

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

Desirable acc portal features

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

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.

  • Caution: Giovanni is a constantly evolving data exploration tool!

Five practices for agile seamless data federation

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
