Soil moisture forecasting at property level
Soil moisture information and forecasts are of great help in dryland farming, to provide early warning of drought, flood and fire risk, and to monitor environmental health, to name a few. Current soil moisture mapping services from models and satellite remote sensing are useful, but are often too coarse or inaccurate or do not provide forecasts.
With support from the Terrestrial Ecosystem Research Network and together with the Bureau of Meteorology, we are developing more accurate soil moisture mapping methods with greater spatial detail at the level of individual properties. We do this by combining different rainfall and soil moisture information sources through data assimilation. Our techniques can operate at different scales, providing forecasts at 10 km resolution for the entire world, down to 25 meters for individual properties.
