************************************************************************
PhD topic on the ?Role of aerosols in Arctic climate change?
at Laboratoire Atmosphères, Milieux, Observations Spatiales (LATMOS),
Universite Pierre et Marie Curie/IPSL, Paris, France
************************************************************************
Applications for the above PhD topic are solicited.

The Arctic is a beacon of climate change warming faster than other regions
and also under-going unprecedented changes such as the decline in
summertime sea-ice. Whilst global warming due to long-lived greenhouse
gases is certainly important, radiative forcing from short-lived
pollutants such as ozone and aerosols may also be playing an important
role. Our knowledge about the contribution of aerosols to direct and
indirect forcing requires improved quantification especially from
anthropogenic and boreal fire sources transported to the Arctic.  Analysis
of data collected during the International Polar Year have shown that
pollution layers transported to the Arctic often contain complex mixtures
of aerosols and are often rather fine scale making then difficult to
simulate in global-scale models.

The thesis work will make use of the regional Polar-WRF model including
chemistry and aerosols for case studies of particular events observed, for
example, as part of POLARCAT (see www.polarcat.no) airborne campaigns.
Analysis of results will focus on quantification of pollutant transport,
analysis of aerosol distributions and their radiative impacts in order to
improve our knowledge about the role of aerosols in Arctic climate change.
Deposition of aerosols on snow/ice, notably black carbon, suggested as an
important mechanism leading to changing surface albedo and sea-ice
melting, may also be studied.

The research will be carried out within the tropospheric chemistry and
aerosol group at LATMOS and within the framework of on-going and new
projects focusing on the role of short-lived pollutants in Arctic climate
change. Data collected during new campaigns planned in 2012 may also be
studied. It will involve collaboration with French, European and other
international groups, in particular the US Pacific Northwest National
Laboratory (PNNL).

Applications for financial support need to be submitted before 1 June
2011. If interested please send a CV together with names/emails of at
least 2 referees before 10 May 2011 to Kathy.Law@latmos.ipsl.fr and
Jean-Christophe.Raut@latmos.ipsl.fr. Experience in atmospheric science and
modelling is desirable together with knowledge of computer programming
(Unix, Fortran, IDL/Matlab) and English and/or French.

The position is open until filled and will be located at the Universite
Pierre et Marie Curie/ LATMOS, located in central Paris at the Jussieu
campus (http://www.latmos.ipsl.fr/ and http://www.upmc.fr ). LATMOS is a
joint CNRS/University laboratory which is also part of the Institut Pierre
Simon Laplace (IPSL) (http://www.ipsl.fr/). It carries out research into a
wide range of topics related to atmospheric science.
