A multi-frequency microwave radiometer system for environmental research: A new capability for airborne remote sensing of key environmental variables will be established. The unique P-, Ku- and Ka-band passive microwave radiometer system will provide information on soil moisture, surface temperature and vegetation, and allow for a new satellite concept to be demonstrated. By combining with an existing L-band radiometer, data can be collected simultaneously at P-, L-, Ku- and Ka-bands, with increased spatial resolutions accordingly. The shorter wavelength, but higher spatial resolution data can be used to enhance the spatial resolution of the longer wavelength data, resulting in a capability to derive long wavelength observations from space at unprecedented spatial resolution.Read moreRead less
P-band soil moisture sensing from space. This project aims to develop radiative transfer models to demonstrate that a P-band radiometer capability can remotely sense the top ~15cm layer of soil moisture, through a series of tower and airborne field experiments. Timely soil moisture information on this near-surface layer is critical to improved water management for food production in the face of extreme climate variability. Current satellite technologies are limited to the top ~5cm layer of soil ....P-band soil moisture sensing from space.

Timely soil moisture information on this near-surface layer is critical to improved water management for food production in the face of extreme climate variability. Current satellite technologies are limited to the top ~5cm layer of soil using an L-band radiometer. This project is expected to give farmers the soil moisture data they need to optimise their available water resources to maximise food productionRead moreRead less

Forecasting live fuel moisture content, the on/off switch for forest fire. Dry forest fuels are a precursor of large bushfires. This research aims to develop, for the first time, a model to reliably forecast the moisture content of live fuels (e.g. the foliage and fine branches of shrubs and trees). This will be achieved by combining (i) satellite-derived estimates of live fuel moisture content, (ii) forecasts of soil moisture, and (iii) plant physiological responses to soil dryness. Forecasts o ....Forecasting live fuel moisture content, the on/off switch for forest fire. Dry forest fuels are a precursor of large bushfires. This research aims to develop, for the first time, a model to reliably forecast the moisture content of live fuels (e.g. the foliage and fine branches of shrubs and trees). This will be achieved by combining (i) satellite-derived estimates of live fuel moisture content, (ii) forecasts of soil moisture, and (iii) plant physiological responses to soil dryness. Forecasts of live fuel moisture content will deliver an early warning system of the risk of bushfires. These forecasts will also facilitate improved planning of prescribed burns: if fuels are too dry there is a risk of burns escaping, conversely, if fuels are too wet there is a risk that burns will fail to meet objectives.Read moreRead less
Towards operational monitoring of key climate parameters from synthetic aperture radar. Agricultural productivity is a major contributor to the Australian economy, but is experiencing significant stress in response to climate change. Moreover, soil moisture controls vegetation dynamics that contribute to carbon storage, atmospheric processes leading to severe weather, and runoff generation processes leading to floods and runoff yield from urban water storage catchments. Consequently, high reso ....Towards operational monitoring of key climate parameters from synthetic aperture radar. Agricultural productivity is a major contributor to the Australian economy, but is experiencing significant stress in response to climate change. Moreover, soil moisture controls vegetation dynamics that contribute to carbon storage, atmospheric processes leading to severe weather, and runoff generation processes leading to floods and runoff yield from urban water storage catchments. Consequently, high resolution time-series information on soil moisture and vegetation status from space represents a powerful tool for understanding climate change impacts on Australia. It is therefore imperative that products be developed specifically for the Australian environment to take full advantage of radar data from satellites.Read moreRead less
Impacts of extreme hydro-meteorological conditions on ecosystem functioning and productivity patterns across Australia. As Earth’s climate continues to change, the frequency and intensity of warm droughts, extreme precipitation patterns, and heat waves will alter in potentially different ways, ecosystem functioning and productivity with major impacts on carbon and water balance, and food security. The extreme hydro-meteorological conditions that are presently afflicting Australia provide excepti ....Impacts of extreme hydro-meteorological conditions on ecosystem functioning and productivity patterns across Australia. As Earth’s climate continues to change, the frequency and intensity of warm droughts, extreme precipitation patterns, and heat waves will alter in potentially different ways, ecosystem functioning and productivity with major impacts on carbon and water balance, and food security. The extreme hydro-meteorological conditions that are presently afflicting Australia provide exceptional opportunities to study ecosystem-level functional responses using contemporary, in-situ and satellite observational datasets. This project aims to analyse cross-biome and site-level functional responses across contrasting hydroclimatic periods to better understand climate change impacts on ecosystem productivity, resilience, and potential collapse.Read moreRead less

To reduce the uncertainties in estimating and predicting vegetation biomass and to aid in the development of climate change strategies, this project will formulate and explore the first detailed long term aboveground vegetation biomass carbon record for Australia using a series of satellite passive microwave instruments. The spatiotemporal variation in biomass carbon over past decades will be investigated to better understand how it responds to changing climate and human activities. Such information will allow more accurate estimation of future vegetation dynamics and carbon storage. Moreover, an enhanced bushfire danger index that incorporates aboveground biomass information will be developed to more precisely predict the potential damage.Read moreRead less
