The eMAST project aims to integrate ecosystem data from sources like TERN to enable modeling of questions in carbon, water, climate change, land management, fire, climate feedbacks and biodiversity. It provides climate and bioclimate datasets at 1km resolution from 1970-2011. Tools include packages for computing bioclimatic indices and modeling gross primary productivity (GPP) across Australia using OzFlux and satellite data. An example user workflow shows how ePiSaT modeling could be used on TERN data to produce and evaluate continental GPP estimates. eMAST plans to deliver its key datasets and tools through the Research Data Services Infrastructure to advance ecosystem science.
