All of the Earth at High-Resolution in 3D: Scaling Surface Processes From Local to Continental to Global
Abstract
The Earth's surface is typically shaped by local processes that act within regional, continental and global contexts. Traditionally, high-resolution local data are analyzed within low-resolution regional/global context data, yielding uncertainty about the scalability of well-understood local phenomena. This gap between high-resolution local data and low-resolution global data is narrowing due to multiple decades of successful Earth Observing missions that have yielded meter-scale information about the entire Earth's three-dimensional shape and surface composition and how both have changed over the last 25 years. Meanwhile, computation has improved at a rate such that these massive volumes of data can be processed and analyzed efficiently at the global scale. This alignment of data and computation sets the stage for a new era of global analysis of the Earth's geomorphology as a function of time, including forecasts of global surface change in the future. This presentation will discuss how the Polar Geospatial Center at the University of Minnesota is making tens of petabytes of data of the Earth's surface accessible and analyzable to individual researchers and broader communities with the goal of further understanding the wholesale evolution of the Earth's crust.
