Satellite tracking of health threats from grass pollen exposure. This project aims to discover why pollen exposure has increased since the 1960s. Grass pollens are the main environmental allergen source in Australia and the primary cause of allergic diseases. This project will investigate the ecological causes of changing pollen allergen exposures through integrating 40 years of satellite data, field phenology cameras, and pollen traps that track grass pollen sources, their evolution and impact ....Satellite tracking of health threats from grass pollen exposure. This project aims to discover why pollen exposure has increased since the 1960s. Grass pollens are the main environmental allergen source in Australia and the primary cause of allergic diseases. This project will investigate the ecological causes of changing pollen allergen exposures through integrating 40 years of satellite data, field phenology cameras, and pollen traps that track grass pollen sources, their evolution and impact areas. The outcomes are expected to advance knowledge of environmental drivers and enable more accurate pollen forecasts that alleviate the medical and socioeconomic burden of allergic diseases, estimated to cost 30 billion dollars.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

Summary
Characterising changes in Australia’s vegetation for biomass monitoring, carbon accounting and fire hazard mapping. 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 deca ....Characterising changes in Australia’s vegetation for biomass monitoring, carbon accounting and fire hazard mapping. 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
