[Met-jobs] Postdoctoral Fellow in High Alpine Aerosol Research

The Paul Scherrer Institute, PSI, is with 1500 employees the largest
research centre for natural and engineering sciences within Switzerland.
We perform world-class research in three main subject areas: Matter and
Material; Energy and the Environment; and Human Health. By conducting
fundamental and applied research, we work on long-term solutions for
major challenges facing society, industry and science.

The Laboratory of Atmospheric Chemistry (LAC) studies the effects of
anthropogenic emissions on the atmospheric environment. The aerosol
research in our laboratory involves emission characterization, smog
chamber studies and long-term measurements and field campaigns at the
high alpine site Jungfraujoch.

Atmospheric aerosol particles have an impact on the earth's climate via
their interaction with solar radiation and via modification of cloud
properties. These effects remain the largest source of uncertainty in
our current understanding of the earth's climate system. In 1988 the
Paul Scherrer Institute (PSI) initiated an aerosol research program at
the high Alpine Research Station Jungfraujoch (3580 m.a.s.l.). Since
1995 PSI has been responsible for the continuous aerosol measurements
performed at Jungfraujoch within the Global Atmosphere Watch (GAW)
program of the World Meteorological
Organization. Nowadays, the aerosol monitoring program at the
Jungfraujoch is among the most complete aerosol monitoring programs

For this research we are looking for a

Postdoctoral Fellow in High Alpine Aerosol Research

Your tasks
* Responsibility for the continuous aerosol measurements at the high
alpine research station Jungfraujoch; during intensive campaigns you
will be involved in comprehensive aerosol - cloud interaction studies
that are conducted within national and international collaborations
* Application of state-of-the-art aerosol instrumentation including
scanning particle mobility sizers, optical particle counters,
nephelometers, aethalometer, cloud condensation nucleus counters, etc.
* Supervision of PhD students, e.g. by contributing to the development
and employment of a new ice selective inlet for the extraction of ice
crystals in mixedphase clouds and subsequent physico-chemical analysis
of the ice residuals

Your profile
* PhD degree in chemistry, physics, environmental/earth sciences or
* You must have an affinity for practical work with specific experience
in the measurement of airborne nanoparticles as well as an extensive
knowledge of atmospheric aerosols and their impact on climate
* Good communication skills are required along with an ability to work
effectively and creatively as part of a research team involving graduate
students and research staff
* Basic programming skills and proficiency in spoken and written English
are prerequisites

We are looking for a highly motivated individual, who is willing to work
partially at the high altitude of the Jungfraujoch and who is interested
in atmospheric aerosol research. The workplace is mainly located at PSI.
However, during the intensive field campaigns, longer stays at the
station are necessary.
