Ralf M. Staebler

Research Scientist - Air quality, flux and trace gas measurements

Current research and/or projects

  • Micrometeorological techniques: stationary and mobile flux measurement technique development for trace gases and aerosols
  • Micrometeorological aspects of tropospheric chemistry (turbulent transport of reactive trace gases, formation of secondary organic aerosols, dispersion of pollutants)
  • Forest-Atmosphere interactions: Borden Forest Research Station (Fluxnet)
  • Oil and gas sector emissions of greenhouse gases and air pollutants
  • Arctic boundary layer dynamics
