Dr Joelle Buxmann
Joelle is a scientist working in Observations Research and Development, with particular specialisation in remote sensing of aerosols and trace gases including water vapour and ozone.
Areas of expertise:
- Remote sensing of trace gases and aerosols
- Differential optical absorption spectroscopy (DOAS)
- Atmospheric chemistry
Joelle Buxmann started to work for the Met Office in March 2013. Her main interest is remote sensing of aerosols and trace gases including water vapour and ozone.
During June -August 2013 she went on a winter expedition to Antarctica on the research Vessel Polarstern in collaboration with the University of Heidelberg. Her work was focused on detection Halogen oxides and sea salt aerosols in correlation with ozone depletion and mercury deposition.
2008-2012 PhD in Physics, Dissertation topic: 'Bromine and Chlorine explosion in a simulated atmosphere' at the University of Heidelberg. Her work was focused on Smog chamber studies of atmospheric halogen chemistry at Bayreuth Center of Ecology and Environmental Research, Atmospheric Chemistry Research Laboratory.
Besides her laboratory work she conducted a number of field campaigns:
- 2012 Remote sensing using DOAS of SO2 and BrO at Mount Etna (volcano), Sicily, Italy
- 2008 Remote spectroscopic measurements of NO2 and SO2 fluxes at a field campaign at Canadian Oil Sand Open Pit Mining
- 2008 Remote measurements using multi-axis-(MAX)-DOAS of IO and BrO as well as air and soil sampling at salt lakes in Namibia and Botswana, South African continent
- 2008 Vertical profile measurements of NO2 and NO3 using Long-path-DOAS measurements during DOMINO (Diel Oxidant Mechanisms In relation to Nitrogen Oxides) campaign in Southern Spain
- 2007 MAX-DOAS measurements (remote/ spectroscopic) of Halogen oxides on the Research Vessel 'Marion Dufresne'
- 2006 & 2007 Long-path-DOAS measurements of IO, BrO and ClO at Mace Head, Ireland
