六、内容简介：

Natural disaster management requires an ability to i) reliably predict risk of occurrence and ii) monitor in real-time the actual situation on the ground, so that emergency services, government agencies and the community at large can be well informed and able to take appropriate timely evasive action to minimise loss of life and property. Of particular relevance is the need for risk prediction models to have reliable real-time high spatial resolution information on the soil moisture content of areas at risk of flood or landslide, and the fuel and soil moisture content of areas at risk of bushfire. Similarly, emergency personnel need real-time information on the location of flood water inundation along with its dynamics, and location of the fire fronts along with their speed and direction of travel. A fundamental challenge is that current satellite technology, while useful, is not able to meet the operational demands for providing such information. Accordingly, we are embarking on two recently funded projects to address these challenges, including the development of a 200m resolution observational capability using i) an L-band passive microwave radiometer on a High Altitude Platform (HAP), and ii) the L-band synthetic aperture radar data soon to become available from NISAR. Plans and opportunities for collaboration on these two projects will be presented.

七、主讲人简介：

Jeffrey P. Walker received the B.E. (civil) and B. Surveying degrees (Hons.) from the University of Newcastle, Callaghan, NSW, Australia, in 1995, and the Ph.D. degree in water resources engineering from the University of Newcastle, in 1999. His Ph.D. thesis was among the early pioneering research on estimation of root-zone soil moisture from assimilation of remotely sensed surface soil moisture observations. He then joined Goddard Space Flight Center, NASA, Greenbelt, MD, USA, to implement his soil moisture work globally. In 2001, he moved to the Department of Civil and Environmental Engineering, University of Melbourne, Parkville, VIC, Australia, 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 2010, he was appointed as a Professor at the Department of Civil Engineering and Environmental Engineering, Monash University, Clayton, VIC, Australia, where he has continued this research. He is contributing to soil moisture satellite missions at NASA, ESA, and JAXA, as a Science Team Member for the Soil Moisture Active Passive (SMAP) mission and Cal/Val Team member for the Soil Moisture and Ocean Salinity (SMOS) and Global Change Observation Mission—Water (GCOM-W), respectively. Dr. Walker is a Laureate Fellow of Australian Research Council. He is also an IEEE Fellow and general chair of IGARSS 2025.
