Two Post Doctoral Positions in Laboratory Aerosol Measurements at the
Waterloo Centre for Atmospheric Sciences (WCAS)
These positions involve the application of the techniques of Physical
Chemistry to the study of atmospheric aerosols. One will focus on
infrared spectroscopic measurements of the properties of aerosols in
cryogenic flowtubes. This project will continue the successful work
reported in: Zasetsky et al. “Frequency Dependent Complex Refractive
Indices of Supercooled Liquid Water and Ice Determined from Aerosol
Extinction Spectra” J. Phys. Chem. A.; (Article); 109; 2760. (2005)
and “Local Order and Dynamics in Supercooled Water: A Study by IR
Spectroscopy and Molecular Dynamic Simulations” J. Chem. Phys. 121, 6941
(2004). This work explores the cryogenic behaviour of atmospheric
aerosols with applications to the optical properties of atmospheric clouds
and aerosols and the fundamental processes involved in cloud nucleation.
The other position involves the use of chemical ionisation mass
spectrometry for the observation of heterogeneous interactions of OH and
HO2 radicals with atmospheric aerosols. Although some aspects of this new
initiative are still under development, promising preliminary results have
already been obtained. This project will also involve the development of
new methods for the use of an Aerosol Mass Spectrometer in field studies.
Applications from candidates with experimental experience in the relevant
areas of optics, electronics and spectroscopy are encouraged.
The WCAS consists of approximately 30 research and support personnel
working in laboratory aerosol studies, atmospheric modelling and remote
sensing studies. Further information on the technical aspects of the work
involved in these projects may be obtained from Professor J.J. Sloan, WCAS
Research Director ([log in to unmask] ;

The WCAS is located at the University of Waterloo
(http://www.uwaterloo.ca/in the Kitchener-Waterloo urban area
(http://win.uwaterloo.ca/win/, which has a population of approximately
250,000, and is surrounded by a pleasant, mostly agricultural, rural
region.
