NOAA Strategic Plan• Successful, theme-based web pages support NOAA’s mission strategy:
“Engage, advise, and inform individuals, partners, communities, and industries to facilitate information flow, assure coordination and cooperation, and provide assistance in the use, evaluation, and application of information” *
• Websites that present NOAA science, data, analysis and information in a manner that is clear, scientifically validated, useful, interesting and intelligible by a broad audience support NOAA in promoting the
“increased use and effectiveness of climate information for decision makers and managers” *
* NOAA Strategic Plan for FY2003 – FY2008 and Beyond http://www.osp.noaa.gov/docs/NOAA_Final_Strategic_Plan_March31st.

Data Quality Act
• Congress has directed OMB to issue government-wide guidelines for:
“ensuring and maximizing the quality, objectivity, utility, and integrity of information disseminated by Federal agencies …" *
* Section 515(a) of the Treasury and General Government Appropriations Act for Fiscal Year 2001

Tomorrow’s Applications• Distributed Data Access
– Centralized, uniform, consistent access to geographically distributed Arctic Observing System data and products in a common data format
• Web Services– Machine access to data from Arctic Observing
Systems• Automated data assimilation into models
• Collaboratories– Full collaborative sharing of applications over the
Internet• Scientists use networks not airplanes for collaboration

Distributed Data Access
Integrated view of data from 3 sources
![Page 13: Arctic Applications achievable through Information Technology “… combining the interests of the scientific community … with those of the computer science](https://reader036.vdocuments.mx/reader036/viewer/2022062805/5697bfed1a28abf838cb8fe3/html5/thumbnails/13.jpg)
What is a Web Service?Web Services are NOT related to the Web!
• Web Services– Support machine-to-machine data requests
• Published by data holders• Discovered and invoked by data users (computer programs)• Requesting program specifies data subset and variable desired• Based on W3C standards
– XML/Simple Object Access Protocol (SOAP)
– Uniform Description, Discovery and Integration (UDDI),
– Web Service Descriptive Language (WSDL)
– HTTP
– Microsoft, IBM, Sun Microsystems, etc.
• Used in commercial applications• Emerging use for scientific applications

What is a Collaboratory?
“The fusion of computers and electronic communications has the potential to dramatically enhance the output and productivity of U. S. researchers” “… combining the interests of the scientific community … with those of the computer science and engineering community to create integrated, tool-oriented computing and communication systems to support scientific collaboration… called "collaboratories." *

OceanShareNetwork collaboration tool
• All network collaborators see the same computer display– Any participant can add data to a plot, mark a plot, log a comment– Promotes unlimited, spontaneous data exploration and discussion
leading to fruitful scientific collaboration
• Collaboration features– Local, remote data file access and Java graphics– Standard collaboration tool features (annotation, whiteboard, etc)
• Secure LDAP Document Repository– Proposals, papers in progress, data, images– Access control by document or by folder– Accessible from web and desktop
