Dynamics of Physical Systems Jr. Cannon, Robert H.

He is undertaking research on soil moisture remote sensing and data assimilation, including development of the only Australian airborne capability for simulating new satellite missions for soil moisture. His PhD thesis was among the early pioneering research on estimation of root-zone soil moisture from remotely sensed surface soil moisture observations.

In he moved to the Department of Civil and Environmental Engineering at the University of Melbourne as Lecturer, where he continued his soil moisture work, including development of the only Australian airborne capability for simulating new satellite missions for soil moisture. In he was appointed as Professor in the Department of Civil Engineering at Monash University where he is continuing this research.

His primary research ambition is to lead programs in socially relevant research that will have a positive impact on the way we take care of the environment so as to result in an improved quality of life both now and in the generations to come. He believes that the key to this is through improved earth system state and flux monitoring, prediction and reporting, in a way that is relevant to policy and decision making processes, flood and drought prediction and assessment, land and water management, national weather and climate forecasting, etc.

His vision is that this goal will be realised through a combination of i environmental sensing, ii earth system modelling, and iii optimal convergence of model predictions with observations through data assimilation. This is a new area of research that has gained wide spread interest over the past years. A combination of i environmental sensing, ii earth system modelling, and iii optimal convergence of model predictions with observations through data assimilation.

Institute of Electrical and Electronic Engineers, Fellow. American Geophysical Union, Member. My primary research ambition is to lead programs in socially relevant research that will have a positive impact on the way we take care of the environment so as to result in an improved quality of life both now and in the generations to come. I believe that the key to this is through improved earth system state and flux monitoring, prediction and reporting, in a way that is relevant to policy and decision making processes, flood and drought prediction and assessment, land and water management, national weather and climate forecasting, etc.

My vision is that this goal will be realised through a combination of i environmental sensing, ii earth system modelling, and iii optimal convergence of model predictions with observations through data assimilation. Timely soil moisture information is critical to improved water management for food production in the face of climate variability.

This is because the weight of a digital camera or a thermal infrared camera is relatively small, thus easier to be mounted and operated on a drone. Moreover, optical sensors are commercially available at low cost. However, for soil moisture mapping, the instrument which gives the highest soil moisture retrieval accuracy has been proved to be a low-frequency microwave L-band radiometer. While they are usually too heavy and bulky for a drone to carry, this project will trial a newly developed Polarimetric L-band Single-beam Radiometer PLSR which is less than 10kg in weight with an antenna size of 61x61x20cm.

This project aims to establish a new national capability for airborne-radar remote-sensing to provide unprecedented detail on environmental variables including soil moisture, salinity, vegetation and terrain height. This instrument, together with existing radar and radiometer capability, will yield the first airborne satellite simulator of its type in the world, providing Australian and overseas researchers with a unique and affordable tool for world-class pioneering research.

This novel combination of sensors is expected to yield a level of detail that cannot be achieved with any one sensor alone. Applications include increased capability for monitoring of important environmental data, such as information on soil moisture status required for efficient and sustainable water use. This project aims to make road, airport and dockyard pavements smart, low cost, long-lasting, safe, green and adaptable to future transport demands.

The hub will deliver the innovative materials and modelling, smart construction, and rehabilitation systems required for future demands, while enhancing road safety and reducing environmental impact — saving billions of dollars in the short, medium and long term. 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.

In order to validate both the AMSR-2 surface soil moisture product, and the derived root-zone soil moisture and land surface flux exchange through assimilation into land surface models, long-term ground observation of flux data will be collected within the SMAP Test-bed focus site, which is appropriately sized for the AMSR-2 footprint. Agricultural productivity is heavily constrained by soil nutrition, and, in turn fertiliser application strongly impacts crop yield and the cost of crop production.

New sensing technologies and communication protocols are at the cusp of providing state-of-art infrastructure to farmers that will allow them to precisely monitor their soils in high resolution in space and time to optimize their fertiliser application and agricultural productivity. This project aims to develop the basis to rapidly map fertiliser requirements at high resolution across individual farms using a combination of ground-based and autonomous unmanned aerial vehicle UAV -based remote-sensing systems.

New sensing technologies are at the cusp of providing a state-of-art infrastructure to farmers that will allow them to precisely monitor their crop water requirements spatially, so as to optimize their irrigation scheduling and agricultural productivity. Thus, this project aims to develop a smart irrigation system using an L-band radiometer, allowing for precision water delivery using detailed soil moisture information, thus leading to more efficient water use.

This project aims to establish an earth systems monitoring facility, using unmanned aerial vehicles and world-leading sensor technology. It will have the capability to measure the natural and built environment at millimetre to centimetre scales and to monitor rapid changes. The ensuing data and interpretations will be useful for decision-making and policy development amongst government agencies and the agricultural, environmental, civil infrastructure and mining industries.

Current precipitation estimates suffer from the limited availability of rain gauge data in urban areas. However, mobile phone towers abound and the microwave links between them can provide information on rainfall intensity, meaning that these data may be used to supplement the shortfall in raingauge data.

This project will develop the technology to generate precipitation maps using the combination of mobile phone network link, rain gauge and weather radar data.

Melbourne will be the case study, validated using a research microwave scintillometer and super high resolution mobile weather radar. The aim of this project is to quantify the links between water resources, vegetation health and biodiversity in small native and remnant vegetation reserves embedded in urban environments.

The specific objectives are to i quantify water requirements and carbon balances in four reserves within Greater Melbourne hosting native tree species River Red Gum , identified as vulnerable or endangered, and experiencing different rainfall regimes as well as water management practices, ii test a set of measurement methods in-situ and remote sensing to relate water use with tree growth and biodiversity in urban reserves, and iii develop a model for the water balance and vegetation growth to assist in the management of urban reserves and parks.

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.

Mapping near surface soil moisture variation across agricultural fields is currently a challenging problem, especially as part of routine farming operations. Even earth observation satellites are a challenging option, due to the low spatial resolution of the most suitable satellites several kilometres. Moreover, widely used field-based sensors only provide soil moisture measurements at single points, with many sensors required to provide a complete map.

To overcome these issues, a proximal sensing technique for soil moisture mapping is proposed, which uses the ground reflected signals from Global Navigation Satellite Systems such as the Global Positioning System collected from tractors and other such farm equipment as they work the paddocks.

Estuaries are iconic recreational areas providing both ecological habitat and millions of dollars in revenue to the tourism and fisheries industries. How estuaries respond to human pressures is highly variable with some such as the Gippsland Lakes succumbing to algal blooms, whilst other heavily nutrient laden systems such as the Werribee Estuary support extremely high fish populations.

This project aims to lead to an understanding of the links between freshwater flow, blue-green algal blooms, and recruitment of a key fishery species, black bream. The outcome of the project aims to give catchment managers greater confidence in setting levels of environmental flows that will both support fish populations but also mitigate against algal blooms. The aim of the project is to improve the understanding of different land use implications on water resource and land productivity.

The project aims to use a paired-catchment study that compares the carbon and water balances in two catchments in the high rainfall zone in south western Victoria. One catchment is used prevalently for grazing, while the other is predominantly planted with blue gums.

The main objectives of this project are: to quantify the effect of different agricultural land uses on the catchment water balance; to estimate the trade-off between carbon sequestration and water resources related to tree plantations and pastures; and to develop models at different spatial scales of catchment water balance for land-use management. The hypothesis of this project is that remote sensing can be a very helpful tool for operational water management, with a particular focus on flood forecasting.

For this purpose, remote sensing data will be used in two different ways. First, estimated soil moisture profiles from hydrologic models will be improved through the merging of these model predictions with remotely sensed surface soil moisture values. This is expected to have a beneficial impact on modelled hydrographs.

Second, estimated flood inundations and water levels from hydraulic models will be improved through merging these model results with remotely sensed observations of flood inundations or water levels.

This is expected to improve the predictive capability of the hydraulic model. Overall, using remote sensing data in flood forecasting is expected to lead to better early warning systems, management of floods, and post-processing of flood damages. This is expected to have a strong future beneficial impact on flood management practices in Australia. 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.

MoistureMonitor, 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. The proposed infrastructure seeks to establish a new national capability for high spatial and temporal resolution weather radar data acquisition with application to a range of environmental fields.

Its compact trailer mounted design makes it suitable for applications across Australia, thus complementing our sparse national weather radar network, which is limited by the quality and coverage of many of its current radars.

This new capability will allow Australian researchers to undertake world-class research on environmental prediction hitherto impossible. The integration of low resolution SMOS observations into finer resolution hydrologic models poses significant challenges.

Therefore, this study aims at developing a robust end-to-end methodology that allows for the assimilation of SMOS data either brightness temperature or soil moisture into land surface models and for assessing the usefulness of SMOS data with respect to flood forecasting. The aim of the study is to demonstrate the potential and limits of the SMOS level 1 and level 2 products and their benefits for flood prediction. Current flood forecasts have a number of error sources that reduce their accuracy.

The success of this study will result in a more accurate flood warning system for Australia. Economic, social, and environmental planning for a carbon-constrained future requires a capacity to monitor climate change impacts on vegetation and soil moisture at a level of detail that does not currently exist.

While radar measurements from satellites can provide this important information, the signals are confounded by complex interactions with the Earth surface. Using airborne radar data together with detailed ground measurements, models of this complex interaction will be developed and tested for subsequent time-series application to satellite data across Australia. Soil moisture is a highly critical resource for the Australian agricultural economy which is stressed by climate change.

Daily monitoring of paddock scale soil moisture from space represents a powerful tool to inform land management, allowing accurate crop yield and pasture growth predictions. At the continental scale, soil moisture information will result in better weather, climate and extreme flood prediction skill and the ability to assess the effects of future climate change on Australia. It is therefore imperative that active passive soil moisture retrieval algorithms be developed specifically for the Australian environment in order to take full advantage of the SMAP remote sensing mission when it is launched in This is particularly relevant in rural Australian catchments with competing needs for scarce water resources, including irrigation to sustain farming communities, maintaining adequate flows for river health, and seasonal flooding for fragile eco systems.

Accurately predicting key water balance components across catchments is crucial for improved water resource planning. Continuously constraining model predictions with time series of spatial data can identify weaknesses in model physics for correction and make model scenario testing more reliable so better water management decisions can be made.

Knowledge of the spatial and temporal variation of surface and root zone soil moisture content is critical to environmental sustainability and risk adverse farm management. A paddock scale soil moisture prediction tool will allow i grain growers to make informed decisions of what to plant and when, based on likely germination rates and crop yield, ii graziers to be proactive regarding management of stocking rates based on likely pasture growth, and iii better weather and climate prediction skill.

At regional scales moisture information can be used to support claims of drought exceptional circumstances. Sustainable use of this resource requires an improved understanding of its water balance, particularly the large component of vertical leakage. This project proposes to use isotopic and geochemical techniques, in addition to physical monitoring of evaporation losses, to constrain the near-surface component of vertical leakage from the GAB in South Australia.

Sampling will be optimally targeted and scaled up using detailed mapping of the near-surface leakage zones from remote sensing. This study will result in improved understanding and management of this critical resource. The proposed infrastructure will give Australian researchers the most advanced capabilities available world wide in airborne remote sensing of the environment.

By combining hyper spectral scanning, with full wave form resolving Light Detection and Ranging LIDAR , microwave scanning and sythetic aperture RADAR, flown simultaneously on the most cost efficient and technologically advanced research aircraft, it will be possible to assess and monitor a wide range of parameters not accessible to airborne methods before. We aim to improve the accuracy of soil moisture retrieval from satellite-based passive microwave systems.

First, data collected from the recent Australian National Airborne Field Experiments NAFE by the University of Melbourne will be used to evaluate and test the data assimilation framework developed at the University of Reading for snow mass modelling in the context of soil moisture retrieval. Second, techniques used at the University of Reading for deriving vegetation structural information from airborne scanning LiDAR will be developed for application to a wider range of vegetation types and larger spatial scales, and applied to the NAFE data sets to explore the effects of improved vegetation characteristics on the retrieval of soil moisture from passive microwave observations.

In chaos theory , the butterfly effect is the sensitive dependence on initial conditions in which a small change in one state of a deterministic nonlinear system can result in large differences in a later state. The term is closely associated with the work of mathematician and meteorologist Edward Lorenz. He noted that butterfly effect is derived from the metaphorical example of the details of a tornado the exact time of formation, the exact path taken being influenced by minor perturbations such as a distant butterfly flapping its wings several weeks earlier. Lorenz discovered the effect when he observed runs of his weather model with initial condition data that were rounded in a seemingly inconsequential manner.
