  1. USE CASE FOR SEMANTICS GROUP A.K.Sinha Use case presentation, Arlington , April 30-May 1, 2012

  2. Volcanism and Climate • Abundant data and models already exist • Extreme heterogeneity of data: from sensors to geologic maps • General high level conceptual semantic framework for volcanism exist • Data discovery and integration challenges: simple to complex queries • Knowledge modeling challenges: linking processes and models towards new understanding of knowledge discovery • Societally relevant and strong community support • Links many of the earth’s realms • Well suited for workflow, data mining and other Group challenges A.K.Sinha Use case presentation, Arlington , April 30-May 1, 2012

  3. Resolve the signature of an eruption in the terrestrial lower atmosphere by “determining the statistical signatures of both volcanic and solar forcings on the height of the tropopause”. This specific science template was motivated for developing methods to work across science disciplines , data heterogeneity and applicable processes in search for indicators of volcanic eruptions that create changes in the atmosphere From Fox et al., 2007 A.K.Sinha Use case presentation, Arlington , April 30-May 1, 2012

  4. Data associated with just volcanoes !!!! Nyamuragira Nyiragongo Sarah Colclough Cambridge University A.K.Sinha Use case presentation, Arlington , April 30-May 1, 2012

  5. USGS Physical quantity versus measured as quantity NOAA Value and units? USGS Reference frame? Reference units? A.K.Sinha Use case presentation, Arlington , April 30-May 1, 2012

  6. Examples of some queries What species reinhabit disrupted volcanic terrain Who is at risk through varying types of volcanic eruptive products What is the relationship between eruptive intensity, volume and gas content and impact on global climate Leading to Learning about processes leading to eruptions and to facilitate predictions Social impact of volcanism…cities at risk A.K.Sinha Use case presentation, Arlington , April 30-May 1, 2012
