eMAST : Data assimilation
![Page 4: EcoTas13 BradEvans e-MAST framework](https://reader034.fdocuments.net/reader034/viewer/2022051610/549cb0dcb47959c4318b47ac/html5/thumbnails/4.jpg)
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
![Page 5: EcoTas13 BradEvans e-MAST framework](https://reader034.fdocuments.net/reader034/viewer/2022051610/549cb0dcb47959c4318b47ac/html5/thumbnails/5.jpg)
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?
![Page 6: EcoTas13 BradEvans e-MAST framework](https://reader034.fdocuments.net/reader034/viewer/2022051610/549cb0dcb47959c4318b47ac/html5/thumbnails/6.jpg)
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?
