Research brief: Revisiting the 1888 Centennial Drought
by Alvin Stone | Jan 12, 2021 | Research briefs, RP3 Drought | 0
To shed more light on short droughts of the past, CLEX researchers took advantage of a newly released dataset from the Bureau of Meteorology to re-examine the infamous Centennial Drought of 1888. Using the new dataset along with historical station data, they analysed monthly rainfall variability across south eastern Australia throughout 1888.

by Alvin Stone | Nov 27, 2020 | Research briefs, RP3 Drought | 0
This paper details a new approach to evaluating the performance of land surface models, the component of climate and weather models that simulates land surface processes. It focuses on the cycle of solar radiation during daylight hours and how the energy from the sun is exchanged between the land surface and lower atmosphere.

by Alvin Stone | Nov 24, 2020 | Research briefs, RP3 Drought, Uncategorized | 0
In this paper, the researchers investigated how dryness, represented by the aridity index, affects the inter-annual variability of ecosystem iso/anisohydricity at the regional scale, estimated using satellite microwave vegetation optical depth observations.

by Alvin Stone | Nov 23, 2020 | Research briefs, RP3 Drought | 0
CLEX researchers and colleagues examined the contribution to uncertainty in simulated future changes in crop yields using the change-factor method and an additional, more sophisticated, statistical downscaling method of generating realistic future climate data from climate model output.
Read MoreResearch brief: New roadmap aims to quickly integrate real-world data into ecosystem models
by Alvin Stone | Oct 20, 2020 | Research briefs, RP3 Drought | 0
An international group of researchers performed a critical review of the information infrastructure that connects ecosystem modelling and measurement efforts. This group has now proposed a roadmap to community cyber-infrastructure development that can reduce the divisions between empirical research and modelling, accelerating the pace of discovery.
Read MoreResearch brief: How uncertainties in data and drought indices affect drought identification
by Alvin Stone | Sep 24, 2020 | Research briefs, RP3 Drought | 0
CLEX researchers examined the uncertainties of the input data of three commonly used drought indices, with the data coming from different sources, including observations and reanalysis. The ability of these indices to detect drought was assessed against soil moisture from multiple global land surface models.

by Alvin Stone | Aug 10, 2020 | Research briefs, RP3 Drought | 0
CLEX researchers and colleagues find soil moisture variations need to be considered over at least a decade before a steady-state assumption can be made.

by Alvin Stone | Jul 24, 2020 | Research briefs, RP2 Heatwaves and cold outbreaks, RP3 Drought | 0
CLEX researchers addressed the error compensation issue for temperature extremes by defining a novel performance metric that identifies those models that can simulate temperature extremes well and simulate them well for the right reasons.

by Alvin Stone | Jun 18, 2020 | Research briefs, RP3 Drought | 0
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.
