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.
Research brief: How the IOD Changes with global warming
All data sources agree that positive IOD events are becoming stronger and occur more often and that the mean-state of the Indian Ocean is moving towards a more positive IOD-like state due to enhanced warming in the west compared to the east.
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.
