Curated Data Albums for Earth Science Case Studies



Case study analysis and climatology studies are common approaches used in Atmospheric Science research. Research based on case studies involves a detailed description of specific weather events using data from different sources, to characterize physical processes in play for a given event. Climatology-based research tends to focus on the representativeness of a given event, by studying the characteristics and distribution of a large number of events. To gather relevant data and information for case studies and climatology analysis is tedious and time consuming; current NASA Earth Science data systems are not suited to assemble multi-instrument, multi mission datasets around specific events. For example, in hurricane science, finding airborne or satellite data relevant to a given storm requires searching through web pages and data archives. Background information related to damages, deaths, and injuries requires extensive online searches for news reports and official storm summaries.

We are currently working on developing knowledge synthesis engine to create curated “Data Albums” to support case study analysis and climatology studies.  The technological challenges in building a reusable and scalable knowledge synthesis engine are several. First, how to encode domain knowledge in a machine usable form? This knowledge must capture what information and data resources are relevant and the semantic relationships between the various fragments of information and data. Second, how to extract semantic information from various heterogeneous sources including unstructured texts using the encoded knowledge?  Finally, how to automatically design of the structured database based the encoded knowledge to store all information and data fragments in queryable form? The structured database must allow both knowledge overviews of an event as well as drill down capability needed for detailed analysis.  We are utilizing an application ontology driven framework to build the knowledge synthesis engine.

Our effort will deploy curated Data Albums for two science research areas. The first instance will be a portal for hurricane case studies at the Global Hydrology and Resource Center (GHRC), a NASA Data Center. This portal will auto-generate Data Albums for specific hurricane events, compiling information from NASA field campaign collections and other sources. The second instance will be customized to support NASA’s Short-term Prediction Research and Transition (SPoRT) Center in compiling case studies to evaluate the performance of numerical weather prediction tools for convective weather events.
