Abstract
ACME scientists use simulation ensembles to study how input parameter adjustments effect simulation results. Provenance can aid in explaining the factors that contribute to actual results and if captured in sufficient detail, provenance can be used as a knowledge source to reproduce all or parts of an ensemble. The Provenance Environment (ProvEn) platform helps capture provenance from ACME ensemble runs and visualize it through ProvEn Dashboard. The HArvest Provenance Interface (HAPI) is developed to crawl through the ACME case directories and disclose the data as provenance messages to ProvEn. The collected provenance can be visualized through ProvEn dashboard which helps with results explanation.
