Research brief: Predicting the risk of drought-induced tree mortality in Australia
CLEX researchers implemented a new model of plant hydraulics into the Community Atmosphere Biosphere Land Exchange (CABLE) land surface model to robustly project future drought impacts on Australian vegetation.

Research brief: Including vegetation structure improves photosynthesis in land surface models
CLEX researchers and colleagues that adding vegetation canopy architecture with zenith angular variations significantly improved photosynthesis prediction in light-limited ecosystems.

Research brief: what causes the annual Central American Drought?
CLEX researchers investigate the mysterious annual mid-summer drought that occurs in Central America and Mexico, and find a range of regional influences that alter its timing and characteristics.

Research brief: New product improves satellite rainfall estimates for data-scarce regions
Researchers have developed a hybrid approach to estimate recent rainfall that combines satellite-based rainfall estimates with satellite-based soil moisture estimates. When this approach was tested against independent rain gauge measurements it showed notable improvements.

Latest climate models show more intense droughts to come
An analysis of new climate model projections by Australian researchers from the ARC Centre of Excellence for Climate Extremes shows southwestern Australia and parts of southern Australia will see longer and more intense droughts due to a lack of rainfall caused by climate change.

Research brief: CMIP6 models show some improvement over Australia
Australian researchers assess the ability of recently released climate models to simulate the climate of Australia and the new scenarios for 21st Century climate change.

Don’t look to mature forests to soak up carbon dioxide emissions
Models used to project future climate change, and impacts of climate change on plants and ecosystems, currently assume that mature forests will continue to absorb carbon over and above their current levels, acting as carbon sinks. The findings from this research suggest that those sinks may in actual fact be weaker or absent for forests on low-nutrient soils.

Research brief: New energy/water dataset obeys energy conservation laws
This study presents a method for combining multiple observational datasets of the energy and water budgets at the land surface from different sources into a single hybrid dataset that conserves energy and mass.

Research brief: Future Australian drought could lead to high carbon releases
In this study, CLEX researchers and colleagues analysed the magnitude and sensitivity of vegetation responses to the Millennium Drought with satellite-derived information.

Research brief: Climate models overestimate ecosystem productivity to rainfall
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.

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).

Explainer: Focus on drought-breaking rain helps us understand Australian droughts
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.
