delivering real-time satellite data to a broader audience
This paper presents our work of enhancing the existing cyberinfrastructure using Web 2.0 technologies for delivering real time satellite data to a broader audience. As a resource provider on the TeraGrid, Purdue University hosts several data collections for earth and environmental research, including a large number of satellite data products that are received and generated in real time at the Purdue Terrestrial Observatory (PTO). A science gateway portal, named PRESTIGE, has been developed as the access point to services related to the satellite data generated at PTO. It remains a major challenge to help potential users easily discover the data products that are available and access them based on their needs. In an effort to address this challenge, we developed different interfaces for different user groups. We use the Google gadget as a new way to deliver satellite data and information to a broad user community. Three satellite data viewer gadgets have been developed and deployed. They connect to a data generation and processing system at the backend. The gadgets embrace the recent Web 2.0 technologies in bringing the rich access and sharing capabilities available in the general cyberspace to the scientific user communities.
