In this study, CLEX researchers and colleagues analysed the magnitude and sensitivity of vegetation responses to the Millennium Drought with satellite-derived information.Read More
In this study, CLEX researchers and colleagues tested the ability of 10 terrestrial biosphere models to reproduce observed sensitivity of ecosystem productivity to rainfall changes (rainfall exclusion/irrigation) at ten sites across the globe.Read More
Research brief: Higher streamflow variability than rainfall creates challenges for hydrologic variability framework.
New research shows, contrary to expectation, the inter-annual variance in evapotranspiration is much smaller than for precipitation, runoff and soil storage. Accounting for hydrologic covariances explains why it is possible for variability in the principal sink (e.g., streamflow) to exceed variability in the source (precipitation).Read More
In this study of drought and rainfall over the Murray Darling Basin, CLEX authors find that the length of time between La Niñas and negative-IODs is an important indicator of the likelihood of drought for this region.Read More
This work describes a new cross-scale modelling framework for urban environments and applies it to calculate how electricity and gas demand will change under future climate change and air conditioner (AC) ownership scenarios.Read More
CLEX researchers evaluated an updated version of CABLE climate model within a WRF physics ensemble over the CORDEX AustralAsia domain. Results were strongly dependent on the region of interest.Read More
CLEX researchers and colleagues found the Aridity Index was too simplistic to capture the many aspects that define landscape aridity, including the amount of rainfall, water resources and vegetation productivity, and is a poor indicator of future aridity changes.Read More
With projected increases in temperature in the future, the amount of water vapour that can be held at saturation – before it condenses into clouds, dew or water film – increases exponentially. As this deficit increases plants tend to close their stomata, which reduces water fluxes into the boundary layer. Do models currently capture the observed leaf-level response to increasing vapour pressure deficit? What about at very high levels of this deficit?Read More
This paper documents the efforts of the international weather data rescue initiative ACRE, the International Surface Temperature Initiative and researchers that took part in workshops held in Bern, Switzerland, in June 2018 to rescue and digitize meteorological measurements taken prior to 1850 from around the world.Read More
Melbourne’s existing water supplies may face pressure if global warming hits the 2℃ level. The effects of drying and warming in southern Australia are expected to reduce natural water supplies. If we overshoot 2℃ of warming, even the desalination plant might not provide enough drinking water to a growing population.Read More
This study showed that phosphorus availability reduced the projected CO2-induced biomass carbon growth by about 50% over 15 years compared to estimates from carbon and carbon-nitrogen models.Read More
This release is to advise the community that an ACCESS Oversight Committee has been formed initially comprising Christian Jakob, Rachel Law, Helen Cleugh, Andy Pitman, Tony Hirst, Peter May, David Karoly and Ben Evans. Terms of reference have been agreed to by the group and can be found at the end of this document.Read More
