Space gravity: squeezing the last drop of hydrological information out of current and future missions. Australia needs space gravity measurements in order to estimate regional-scale total water storage changes on our continent. This project will deliver the analysis capability required to exploit all the measurements of the current Gravity Recovery and Climate Experiment (GRACE) mission and to place Australia in a state of readiness for the 2017 GRACE Follow On mission.
Quantifying sea-level trends and extremes along Australia's coastal margin. Multi-decadal changes in sea-level, and sea-level extremes, cannot be well quantified along most global coastlines, including Australia's, because the high spatial variability of sea-level is under-sampled by the sparse set of long, high quality tide gauge records. Satellite altimetry provides an alternative data source with greater spatial sampling, yet experiences contamination from land within tens of kilometres from ....Quantifying sea-level trends and extremes along Australia's coastal margin. Multi-decadal changes in sea-level, and sea-level extremes, cannot be well quantified along most global coastlines, including Australia's, because the high spatial variability of sea-level is under-sampled by the sparse set of long, high quality tide gauge records. Satellite altimetry provides an alternative data source with greater spatial sampling, yet experiences contamination from land within tens of kilometres from the coast and also suffers from regionally correlated biases. This project proposes to address these problems through re-tracking radar altimetry waveforms to derive new data in the coastal margin, enabling the production of new inferences on sea-level change and extremes at dramatically improved spatial resolution around Australia.Read moreRead less
MoistureMonitor: A multi-mission soil moisture monitoring system for a water limited future. A long-term soil moisture record for Australia is critical to understanding climate change feedback mechanisms and their impacts on water management. This project will validate, downscale and harmonise soil moisture retrievals from three satellite missions across this decade, each using a new and different low resolution antenna technology and interpretation approach. Moisture Monitor, the framework to d ....MoistureMonitor: A multi-mission soil moisture monitoring system for a water limited future. A long-term soil moisture record for Australia is critical to understanding climate change feedback mechanisms and their impacts on water management. This project will validate, downscale and harmonise soil moisture retrievals from three satellite missions across this decade, each using a new and different low resolution antenna technology and interpretation approach. Moisture Monitor, the framework to deliver this soil moisture record, will be verified using airborne campaigns and hydrological monitoring infrastructure in the Murrumbidgee catchment. Important outcomes will be validation of a new soil moisture satellite and development of a high resolution soil moisture product for improved land and water management and policy for Australia.Read moreRead less
