3. What is the NYCCSC? A 3-year project funded by
With additional partners
Northeast States for Coordinated Air Use Management (NESCAUM), SUNY Collect of Environmental Sciences and Forestry, NOAA, and the Cornell University Northeast Regional Climate Center

4. What is the NYCCSC?
Central point of search and access to climate change information relevant to NY State
Audience to include state & local policy makers, researchers, and members of the public
Inform future research and enable scientifically sound and cost-effective policy decisions
Site launched August 2016
No CENTRAL point of search – multiple websites – can we access all this information in the same place
“No central, searchable repository or clearinghouse to collect, store, summarize, interpret, and disseminate
NYSERDA: nystate energy research and development authority
SUNY ESF: college of environmental science and forestry,
NRCCL Northeast Regional Climate Center,
NESCAUM: Northeast states for coordinated air use management, national oceanic and atmospheric administration
Long term vision: regional resource for Northeast
Information: relevant, quality
Leverage and improve upon the capabilities of existing state, regional and federal climate-related sites

5. User-centered design approach
Iterative design and refinement
Multiple rounds of user testing and feedback
Interviews, think alouds, focus groups
Evaluating site as a whole
Evaluating specific features or functionality
Project team and stakeholders

6. Site Demo Multiple types of content
Multiple entry points for discovery/browsing
Textual search
Faceted search
Geographic search
Links between content and climate change concepts

26. Wouldn’t it be great if…
The richness of the underlying model
Could be leveraged for
Improved visualization/navigation/display/interface design?
Bringing in external linked data relationships?
Alignment with other ontologies?
