Imtiaz Dharssi

Land Surface Modelling and Data Assimilation

Current work and responsibilities

Imtiaz Dharssi has extensive research experience in land surface data assimilation and modelling. His priority is to turn research into solutions leading to better operational forecasts of weather as well as improving the monitoring and prediction of natural hazards.

Imtiaz led a project at the UK Met Office to assimilate remotely sensed soil wetness measurements from the Advanced Scatterometer (ASCAT) instrument on the Meteorological Operational (MetOp) satellite. A computationally efficient scheme to assimilate the ASCAT soil wetness data was developed. Operational implementation of the ASCAT soil wetness assimilation was achieved in 2010. The UK Met Office is the first weather forecasting centre to operationally assimilate satellite derived soil moisture.

Imtiaz leads a project to improve the monitoring and prediction of bushfires. This project is co-funded by the Bushfire and Natural Hazards CRC.
