Dr Robert Tubbs
Robert works on the assimilation of observations into convective-scale NWP models, with a particular focus on satellite radiance observations.
Areas of expertise
- Assimilation of infra-red radiance observations
- Assimilation of satellite-derived cloud information
- Development of convective-scale data assimilation systems
- Fourier optics and optical measurements of turbulent mixing
Robert is currently developing a data assimilation system for the WCSSP southeast Asia region, a scientific research programme supported by the UK Government’s Newton Fund. He has also been researching the blending of large-scale structure from synoptic-scale models into regional convective-scale data assimilation systems. Robert supports the partner countries in the WCSSP southeast Asia project on the development of regional models. This work aims to build capability to underpin services that support weather resilient economic development and social welfare.
Robert also works on the assimilation of satellite radiance observations into the UKV 1.5km-resolution Met Office Numerical Weather Prediction (NWP) model. This is primarily aimed towards better representation of the atmosphere (particularly cloud) in the UKV model, for both short-range NWP forecasts and for nowcasting. Robert provides regular updates to the satellite data assimilation for the UKV NWP model and analyses the impact of these updates on the performance of the UKV system.
Robert works closely with other members of the Convective-Scale NWP group, with members of the Satellite Radiance Assimilation group and also with staff from the Regional Model Evaluation and Development team.
Robert has worked for the Met Office since January 2008. Prior to joining the Met Office, Robert completed a physics MSci degree at the University of Cambridge, and then worked as a metrologist studying laser pulse duration and standards for fibre-optic communication at the National Physical Laboratory (UK). In 2003 Robert completed a PhD at the University of Cambridge studying the effects of turbulent mixing in the troposphere on optical propagation and imaging, followed by four related postdoctoral fellowship positions supported by respectively: the University of Leiden (Netherlands); the European Commission's Marie Curie programme; Arcetri Observatory (Italy); and the Max Planck Gesellschaft (Germany).
Since joining the Met Office in 2008, Robert has focused on the assimilation of satellite radiances into the Met Office UKV model, provided updates to the UKV and SINGV data assimilation systems, and has set-up the WCSSP southeast Asia regional data assimilation system.
