Vacancy for a Postdoctoral Research Associate in Atmospheric Photochemistry
at the University of Bristol, UK.
A post-doc position is available at the University of Bristol to work with
Prof Andrew Orr-Ewing, Prof Mike Ashfold and Dr Dudley Shallcross on the
atmospheric photochemistry of formaldehyde. The experiments involve
simultaneous measurement of formaldehyde absorption cross sections and
quantum yields for the H + HCO radical channel at UV wavelengths in the
range 300 - 360 nm, and under conditions of temperature and pressure
appropriate for the troposphere. Measurements are made at high wavelength
resolution using a tunable UV laser, and the yield for the radical channel
is monitored by cavity ring-down spectroscopy of HCO. Results are
incorporated into computer models to assess the consequences for
tropospheric HOx (HO2 and OH) production.
Representative publications describing our prior work on this project are:
High resolution absorption cross sections of formaldehyde at wavelengths
from 313 - 320 nm, F.D. Pope, C.A. Smith, M.N.R. Ashfold and A.J.
