Richard works on improving observation usage to positively impact forecast products.
Richard's areas of expertise include:
Richard's main focus is the development of an adjoint-based tool for measuring the sensitivity of forecast-error to observations. So-called "observation sensitivities" can be used to give an estimate of the impact of sub-sets of observations on short-range (typically 24-hour) NWP forecasts. This invaluable information helps guide development of the Met Office data assimilation system and also of the global observing system. The tool could also be a valuable addition to our arsenal of observation monitoring tools.
Work has now begun on the application of the adjoint-based FSO method to convective-scale, local-area models. Many important forecast products are derived from the output of these models and it is essential to understand the influence of observations. This is a new area of research promising some interesting science. However, many challenges have yet to be overcome.
Richard joined the Met Office in 2007 after having graduated from the University of Warwick with a BSc in Physics with Computing. His first position was as a member of the Observation Monitoring Team within DAE. This work involved the development, maintenance and use of monitoring systems to ensure the continued quality of observations entering the Met Office's data assimilation system.
