Dr David Rundle

Areas of expertise

  • Radiative transfer

  • Code Optimisation

  • Fortran Programming

Current Activities

David is currently working on improving the performance and accuracy of the RTTOV fast radiative transfer model on the Met Office supercomputer. Due to the large volume of data produced by satellite instruments, it is necessary to use a so-called 'fast model' to process as much as possible in as little time as possible. By improving the performance of the fast model, David's work directly impacts weather forecasting by increasing the number of satellite observations that can be assimilated into the Met Office Numerical Weather Prediction models.

David also works closely with the Met Office Observation Based Research group to extend the Principal Component (PC) functionality within RTTOV to include use over land and in cloudy conditions.

David will soon be working on implementing a scheme that will reduce the warm bias that is seen at some infra-red wavelengths on hyperspectral sounders during the day caused by non-LTE effects.

David also maintains the NWP SAF forum website.

Career Background

David started working in the Met Office Satellite Applications group in 2010 after finishing his PhD in Astrophysics at the University of Exeter. The title of his thesis was 'Molecular Line Transfer Calculations in Star-Forming Regions'.

Before this David was a Maths and Physics undergraduate at the University of Bath (2001 - 2005).
