NOAA National Climatic Data Center Air Quality Data Archive and Access

• Air Quality Forecast Guidance– One hour and eight hour averaged ground level

(surface) ozone concentration– Data quality controlled before dissemination to NCDC– Available via ftp or magnetic tape– From June 1, 2004 thru current

• NWS National Digital Forecast Database Air Quality Guidance contour maps – Available from the NCDC NOAA Operational Model

Archive and Distribution System (NOMADS) http://nomads.ncdc.noaa.gov/data.php

Data Management Issues• Standards

– Open Archival Information System (OAIS)– Web Services– Interoperable– Submission Agreements

• Centers of Data and Data Centers– Data Center:

• Contains computer systems, telecommunications and storage systems• Redundant or backup power supplies, redundant data communications

connections, environmental controls (air conditioning, fire suppression, etc.), and special security devices

• Archive and access• Subject to National Archive and Records Agency guidelines

• Metadata and Documentation• Architectures, policies, practices and procedures

NIDIS – U.S. Drought Portaldrought.gov: A Window on Drought

Information

What is a Portal?Think of a Portal as a hub from which users (NIDIS users!) can access all of the content that they will commonly need. It is a Web site and services that improve the access, processing, and sharing of structured and unstructured information within and across a given “enterprise” through:

Portlets - A portal page is displayed as a collection of non-overlapping portlet windows, where each portlet window displays a portlet. They provide aggregated, reusable access to specific information sources or applications (e.g., web services, mapping applications, search engines).

Web Services - Applications and utilities that allow data exchange in a highly interoperable, standardized language/vendor/platform-neutral manner. Crawlers and other content aggregation are supported.

Communities - A virtual workspace of a portal for collaboration, communication, and information dissemination/collection. Communities contain portlets and projects.

Collaboration through Projects - Workspaces within a community that involves subsets of Portal membership. Projects contain portlets and can be part of one or more communities, facilitating collaboration via overviews, discussions, and document/project management.

Information

What else makes a Portal Powerful?

Customization – Ability to customize the portal page for different user groups and individuals.

Security – Incorporation of security through roles and a fine granularity of privileges. As guest users, the public can access non-proprietary enterprise-wide information and web sites well as selected web sites as appropriate.

Crawlers and Search Engines – Bringing in content from elsewhere on the web. Search content of the portal contained in the pages of the Portal and the Knowledge Directory.

Designing a Portal is a Complex Process

To be successful a portal needs lots of planning and the cooperation of all partners of the project.

NIDIS Portal Phase 2 Work and Beyond

• GIS Features• Enhanced content and linkages• Community collaboration tools and features• Links to emerging early warning networks

and products (soil moisture, satellite, etc.)

• Link to GEOSS/GIDIS• Links to pilot studies• Potential for data and information

management/sharing cross-agency and at all levels

Summary

NIDIS’ U.S. Drought Portal Provides a Window for Interagency Data Collaboration and Dissemination• The initial phase of the USDP (November 2007) is

allowing drought experts and general users to answer key questions about drought on an end-to-end basis.
