Towards a framework for sharing an open set of data and tools for ecosystem modellers

Brad Evans, Ben Evans and Colin Prentice

eMAST : Data assimilation

eMAST’s objectives 2013-2015

DELIVER research data infrastructure to integrate TERN (and other) data streams on the National Computing Infrastructure

ENABLE data assimilation, model evaluation and accreditation and ecosystem model optimization

DRIVE advances in ecosystem science, impact assessment and land management

Driving science questions

CARBON: How much CO2 is exchanged? How much carbon can be stored and where?WATER: What drives water use by ecosystems, and runoff in rivers?CLIMATE CHANGE: How does it change the rules?LAND MANAGEMENT: What will work, in a changing climate?

More driving science questions

FIRE: What are the risks? How can they be mitigated?CLIMATE FEEDBACKS: How will ecosystem changes influence the exchanges of carbon, water and energy with the atmosphere?BIODIVERSITY: What species are threatened? Where are likely refugia? Is there a tipping point?

What eMAST is delivering

High-resolution data products: climate, canopy conductance, water use, primary productionTools for interpolation, downscaling, upscaling, hindcasting, forecastingA state-of-the-art data assimilation system for ecosystem model optimizationSoftware for model evaluation (based on PALS)Top-level ecosystem drivers and targets for models

Summary: Data-model fusion toolsData assimilation collaboration with NEON and NCAR, CSIRO, Macquarie University and the Australian National University- ACEAS workshop on data assimilation early 2014

eMAST : An R-Package ‘emast’ for the computation and visualization of bioclimatic indices

ePiSaT : Collaboration with OzFlux and AusCover to model Gross Primary Production across the landscape, another R-Package ‘ePiSaT’

Protocol for the Analysis of Land Surface Models (PALS) for evaluation of data and models

The future of eMASTContinue delivery of our key datasets through the RDSI, Data Discovery, Visualization & Exploitation… consolidation of our tools and porting them to Raijin.
