Abstract. The distribution of data contributed to the Coupled Model Intercomparison Project Phase 6 (CMIP6) is via Earth System Grid Federation (ESGF). ESGF a network internationally distributed sites that together work as federated archive. Data records from climate modelling institutes are published and then shared around world. It anticipated CMIP6 will produce approximately 20 PB be ESGF. In addition this large volume number value-added services required interact with ESGF; for example...
The Australian Community Climate and Earth System Simulator (ACCESS) has contributed to the World Research Programme’s Coupled Model Intercomparison Project Phase 6 (CMIP6) using two fully coupled model versions (ACCESS-CM2 ACCESS-ESM1.5) ocean–sea-ice (1° 0.25° resolution of ACCESS-OM2). models differ primarily in configuration version their atmosphere components (including aerosol scheme), with smaller differences sea-ice land versions. Additionally, ACCESS-ESM1.5 includes biogeochemistry...
The Pacific Northwest (PNW) has a complex tectonic history and over the past ∼17 Ma played host to several major episodes of intraplate volcanism. These events include Steens/Columbia River flood basalts (CRB) striking spatiotemporal trends Yellowstone/Snake Plain (Y/SRP) High Lava Plains (HLP) regions. Several different models have been proposed explain these features, which variously invoke putative Yellowstone plume, rollback steepening Cascadia slab, extensional processes in lithosphere,...
Australia’s Climate Simulator (ACCESS-NRI) is a national research infrastructure established to support the Australian Community and Earth System (ACCESS) modelling system. Since its launch in 2022, ACCESS-NRI has focused on modernising climate software data practices for ACCESS. Guided by needs of our community, goal make framework outputs more FAIR (Findable, Accessible, Interoperable, Reusable) easier use.   One key challenges achieving ACCESS reliance often...
Developing climate models often requires the ability to access and share extremely large datasets (spanning tens hundreds of terabytes) that are discoverable optimised for high-performance computing (HPC) applications. This is a major challenge, as researchers frequently lack storage resources specialised support needed ensure efficient data management sharing practices across full life-cycle. The challenges evident even when dealing with curated prepared broad access, citation, reuse....
Received 24 March 2011; revised 25 May accepted 31 published 8 July 2011. [1] We present three‐dimensional laboratory modeling of the evolution finite strain and compare these to shear wave splitting observations in Northwest U.S. under High Lava Plains (HLP). show that relationships between mantle flow anisotropy are complicated subduction zones factors such as initial orientation olivine fast‐axis, style subduction, time evolving important. Due increased horizontal shear, systems with a...
Abstract A recent expansion in global seismic anisotropy data provides important new insights about the style of mantle convection. Interpretations these geophysical measurements rely on complex relationships between mineral physics, seismology, and dynamics. We report 3‐D laboratory experiments using finite strain markers evolving time‐dependent, viscous flow fields to quantify range expected patterns within buoyant plumes surfacing a variety tectonic settings. surprising result is that...
To ensure seamless, programmatic access to data for High Performance Computing (HPC) and analysis across multiple research domains, it is vital have a methodology standardization of both services. At the Australian National Computational Infrastructure (NCI) we developed Data Quality Strategy (DQS) that currently provides processes for: (1) Consistency structures needed (HPD) platform; (2) Control (QC) through compliance with recognized community standards; (3) Benchmarking cases operational...
The Australian Earth System Simulator (ACCESS-NRI) is a national research infrastructure designed to support the development and of Community Climate (ACCESS). With strategic goal enhance quality performance ACCESS suite model configurations, ACCESS-NRI supports open release Model Evaluation Diagnostics (MED) framework for system modeling community.  In climate science, evaluation computational models plays pivotal role in assessing their reliability simulating Earth's complex...
It is difficult to reliably build climate models, reproduce results and so replicate scientific findings. Modern software engineering coupled with the right tools can make this easier.  Some sources of complexity that a problem:   Climate models are an imperfect translation extremely complex understanding into computer code. Imperfect because many assumptions made problems tractable. typically number separate different realms earth system, which run independently while...
ACCESS-NRI is a national research infrastructure (NRI) established to support the Australian Community Climate and Earth System Simulator, or ACCESS. The ACCESS suite of software data outputs are essential tools used simulate past future climate, weather systems decision making within Australia. ACCESS-NRI's mission build an open collaborative that will accelerate in system, climate modelling as well enable new not currently possible. facility brings together skills development,...
