Enabling Linked Science in Uncertainty Quantification Research

  1. 1. Enabling Linked Science in Global Climate Uncertainty Quantification (UQ) Research Eric Stephan, Todd Elsethagen Linked Science Problem Provenance Environment (ProvEn) Services Uncertainty quantification (UQ) studies are often difficult to share between Portable Java-based lightweight restful ETL knowledge pipeline Climate Science for a collaborating scientists because they consist of many different interrelated simulation results, analytical reports, and ancillary data describing scientific Sustainable Energy Future rationale and calibrations used for setting parameters. The Climate Science for a Sustainable Energy Study NetCDF Future (CSSEF) is a collaborative project Scientists producing the data need linked science to provide a consistent means to correlate study data to background knowledge describing how the Plan Headers Citation among Oak Ridge National Laboratory, study was conducted. Argonne National Laboratory, Brookhaven Contributed Analysis Simulation Raw Native National Laboratory, Lawrence Berkeley Collaborating scientists using the UQ studies need this knowledge and National Laboratory, Lawrence Livermore references to data provided in a consistent and cross referenced form. Scripts Log files Provenance National Laboratory, Pacific Northwest National Ancillary Laboratory, and Sandia National Laboratories, Info together with the National Center for Atmospheric Research to transform the climateWhat is Data Provenance? model development and testing process andData provenance is historical information describing the people, institutions, thereby accelerate the development of thesoftware, and activities, responsible for creating or modifying data.

A better alternative is to extract from information produced native sources For more information about ProvEn Servicesby scientists conducting the study, simulation log files, workflow logs, ancillary ProvEn Services Pipelinematerials, or scripts, spreadsheets, and pictures used for analysis.
