ATS Seminar Series: Bruce Wilson

The Advanced Technologies Section (ATS) of the National Center for Computational Sciences at ORNL is a world leader in developing and deploying scientific and technical solutions for leadership-class computing environments. The R&D activities of ATS are organized around designing and deploying leadership class systems, developing artificial intelligence solutions for science and smart facilities of the future, and stewardship of data and workflows at scale to enable science. The ATS Seminar Series is a forum for learning from experts and engaging with collaborators to advance their scientific mission.


Seminar Title:

NASA’s Earthdata Cloud Migration: One Approach for Serving and Integrating Large Volumes of Earth Observation Data


NASA’s Earth Observing System Data and Information System (EOSDIS) presently adds over 25 TB of data volume every data.  With upcoming missions such as the Surface Water and Ocean Topography (SWOT) and NASA-ISRO SAR Mission (NISAR), data growth is expected to exceed 125 TB/day by 2023, with bulk processing spikes exceeding 400 TB/day.  While NASA could build and manage the capability to store and deliver this kind of data from the 12 disciplines-focussed EOSDIS Distributed Active Archive Centers (DAACs), users would generally not have the capability to download and process even small fractions of this data.  As a result of these data volume considerations, as well as the recommendations of a 2016 external review panel that considered the efficiency and effectiveness of the NASA DAACs, NASA has moved forward with commercial cloud services as the core of Earthdata Cloud, which is designed to improve the Interoperability and Reusability of NASA Earth observation data.

This talk will provide an overview of EOSDIS, the general architecture for Earthdata Cloud, the challenges of building this kind of system given FISMA and Anti-Deficiency Act constraints, the progress to date of the Earthdata Cloud migration, and the implications of this migration for data providers, the DAACs, and data users.



Bruce Wilson

Group Leader for Remote Sensing and Environmental Informatics (RSEI), Biological and Environmental Systems Sciences Directorate (BESSD)

Dr. Bruce Wilson is the Group Leader for Remote Sensing and Environmental Informatics (RSEI) at Oak Ridge National Laboratory (ORNL) and the Manager for the NASA-funded ORNL Distributed Active Archive Center for Biogeochemical Dynamics (ORNL DAAC). RSEI focuses on building and managing information systems for climate scientists and ecologists. This group provides integrated data products, data analytics, and data management and delivery systems to advance environmental science. The ORNL DAAC is part of the NASA Earth Observing System Data and Information System (EOSDIS), serving as NASA’s archive and distribution point for terrestrial ecology data, particularly ecosystem and carbon cycle data from ground and airborne campaigns.

Bruce joined ORNL’s Environmental Sciences Division in 2006 as the Systems Engineer for the ORNL DAAC, after 18 years experience in the chemical industry, including 11 years at Eastman Chemical Company in Kingsport, a year with Dow Corning Corporation, and 6 years with the Dow Chemical Company. He served as the ORNL DAAC Manager from 2008 to 2010, when he joined ORNL’s Information Technology Services Division, first as the Group Leader for Client and Collaboration Technologies and then becoming one of ORNL’s Enterprise Architects. In 2018, he returned to ESD and the ORNL DAAC Manager role. Bruce holds appointments in the Bredesen Center for Interdisciplinary Research and Graduate Education and the School of Information Sciences in the College of Communication and Information at the University of Tennessee, Knoxville. He is a co-inventor on 4 US Patents, helped found the USA National Phenology Network, and presently co-leads the NASA DAAC Managers Council. Bruce is a Senior Member of the Association for Computing Machinery, earned a BS in chemistry and mathematics from Michigan State University, and earned a PhD in analytical chemistry (chemometrics) from the University of Washington.
