Dr Denise Hertwig

Denise works on the application of dispersion modelling to emergency response scenarios.

Areas of expertise

Denise's areas of expertise include

  • Local-scale turbulent flow and pollutant dispersion in cities
  • Contaminant dispersion for emergency response applications
  • Environmental fluid dynamics
  • Model validation and quality assurance
  • Boundary-layer wind-tunnel modelling
  • Time-series analysis and flow pattern recognition

Current activities

Denise's work focuses on applying the Met Office's Numerical Atmospheric-dispersion Modelling Environment (NAME) to investigate the dispersion of pollutants in the atmosphere with an emphasis on emergency response scenarios ranging from local to global scales.

Initially, Denise investigated performance gains from an optimisation and parallelisation of NAME for emergency applications ranging from chemical to radiological incidents.

Denise currently works on source-term estimation for recent cases of industrial fires in the UK and on validating NAME against field observations of smoke-haze pollution resulting from biomass burning in South East Asia.

Career background

Before joining the Met Office in January 2014, Denise visited at the Tokyo Institute of Technology, Japan, as associate visiting scientist in the Environmental Turbulence Dynamics Group of the Department of Environmental Science and Technology.

From 2010 to 2013 Denise was research assistant at the Environmental Wind Tunnel Laboratory of the University of Hamburg, Germany, where she completed a PhD in the Department of Earth Sciences. Her research focused on investigating urban turbulence patterns and pollutant dispersion in built environments from street to neighbourhood scales, and on validating building-resolving simulations based on computational fluid dynamics approaches against laboratory and field measurements.

Prior to that Denise studied meteorology at the University of Hamburg and at the University of Oklahoma, USA, and received a Diploma in 2009 (German equivalent of a 5-year MSc degree).
