Virtual Observation System for Earth System Model: An Application to ACME Land Model Simulations

Abstract

Abstract-Investigating and evaluating physical-chemicalbiological processes within an Earth system model (EMS) can be very challenging due to the complexity of both model design and software implementation. A virtual observation system (VOS) is presented to enable interactive observation of these processes during system simulation.Based on advance computing technologies, such as compiler-based software analysis, automatic code instrumentation, and high-performance data transport, the VOS provides run-time observation capability, in-situ data analytics for Earth system model simulation, model behavior adjustment opportunities through simulation steering. A VOS for a terrestrial land model simulation within the Accelerated Climate Modeling for Energy model is also presented to demonstrate the implementation details and system innovations.

A Data Analysis Framework for Earth System Simulation within an <i>In-Situ</i> Infrastructure

“…Generating data for post-simulation earth system process investigation quickly becomes a cumbersome task once a simulation Journal of Computer and Communications reaches a fairly large scale with a huge amount of data and daunting input/output cost. A previous pilot effort focused on demonstrating a concept and small-scale (pointwise) prototype [8]. Our current effort is to process global simulations with the integration of scalable in-situ infrastructure and advanced data processing package.…”

“…Earth system scientists widely adopted post-simulation approaches to analyze results, ranging from visual exploration to transitional statistical data analysis. Along with the advances in in-situ infrastructure development [3] [4], high performance computing and artificial intelligence [5], real-time data analysis becomes an innovative approach to investigate Earth system simulation results [6] [7] [8].…”
