Imtiaz Dharssi is a Land Surface Data Assimilation Scientist at Centre for Australian Weather and Climate Research, having previously worked for The Met Office in the UK for over 11 years. Hi reserach interests include:
- Assimilation of satellite derived soil moisture
- The Unified Model soil moisture nudging scheme
- Parametrization of the soil physical properties
- High-resolution soil texture maps for the Unified Model
This research has developed a prototype, high-resolution soil-moisture analysis system called JASMIN, which is a significant improvement in accuracy compared to currently used models. It is based on research that examines the use of land surface models, remotely sensed satellite measurements and data assimilation techniques to improve the monitoring and prediction of soil dryness. The new information will be calibrated for use within the existing fire prediction systems. This retains the accuracy, temporal and spatial resolution of the new product without changing the overall climatology of Forest Fire Danger Index and other calculations based on soil moisture.
