Introduction
• Use of information visualization for climate visualization for better
understanding of visualization tools and techniques and also how the
previous methods in information visualization can be applied to
climate visualization
• In-depth understanding of climate visualization
3
• Detailed analysis and communication of climate change issues and
research results
The three interlinked research areas of climate
visualization.

Background
• Key challenges:
 Complexity of societal and environmental systems
 Vast amount of heterogeneous data on spatial and temporal scales
• Rapid development of computational power and graphics to boost
the representation of large datasets
• Information visualization approach was made but tools were not
enough to give scientific evaluations details
5
CLIMATE VISUALIZATION
• After identification of challenges within climate communication ,
scientists have taken approach based on the selection of data , their
visual representation and the creation of narratives
• Large datasets and complex modelling
6
Tools
• ICEDome
This is a software environment for large scale visualization and
functions as a framework for development of new visualization
techniques. The focus is on using massive multi-dimensional and
time variant data as well as on integrating mixed media in highly
interactive and immersive environments.

• ICEWeb
• This tool lets researchers exchange and edit climate data
through an easy-to-use web application.
• Multiple data layer support
• Time control and advanced coloring
• Spherical and flat map projection
• Visualizing climate tweets

The Worldview project
• In 2008, Researchers of Linkoping University, the Norrkoping
Visualization Centre and the Swedish Meteorological and
Hydrological Institute started the world view project
• provide details based on scientifically validated data to
communicate the complexity of climate change and interaction
with audience
13
The Worldview project
• In 2009,several presentations of 30 minutes were held in immersive
dome environment.

Previously performed evaluations
• Priority given on data, representation, narrative, narrator and
presentation environments
• Conducted with heterogeneous groups
• Questions based on novelty, aesthetics and understanding of the
visual representations
15
Future Directions
• Depth of knowledge on the effectiveness and efficiency of climate
visualization
• Controlled experiments comparing elements
• (Qualitative) usability evaluation of a tool
• Controlled experiments comparing two or more tools
• Case studies of tools in realistic settings
16
CONCLUSION
• Beneficial for the researchers as the new interactive tools help in
communication , analysis , planning and decision making
• Improving existing tools for efficiency and effects of visual
representations of climate change related issues
• Visualization for large variety of audiences
