Dr Joanne Waller

Areas of expertise

  • Data assimilation
  • Uncertainty quantification
  • Improving and measuring observation impact
  • Novel observations


Current Activities

Jo works in the Assimilation of Surface-based Observations group based at [email protected] Unit at the Department of Meteorology, University of Reading. Jo’s work is focused on optimising the assimilation of surfaced based observations via improved observation uncertainty quantification and increased observation density. Her current research considers the impact of assimilating denser observations in the UK regional atmospheric model. She is also investigating new methods that allow the efficient assimilation of observations with spatially correlated errors.


Career Background

Jo joined the Met Office in September 2019. Prior to joining the Met Office she obtained an undergraduate degree in Mathematics from the University of Southampton in 2008. She then completed a MSc in Mathematical and Numerical Modelling of the Atmospheres and Oceans in 2009 and a PhD on ‘Using Observations at Different Spatial Scales in Data Assimilation for Environmental Prediction’, both at the University of Reading. After completing her degree, Jo worked as a post-doctoral researcher at the University of Reading where her main research focus was improving the treatment of observations in data assimilation.
