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. 7 ICEDome 1 2 3 4 5 6 Credit:https://vimeo.com/album/2918709/video/8094521 8 • 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 9 ICEWeb Credit:https://vimeo.com/album/2918709/video/8094521 10 ICEWeb Credit:https://vimeo.com/album/2918709/video/8094521 11 Iceweb Credit:https://vimeo.com/album/2918709/video/8094521 12 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.
