The Laboratoire de Glaciologie et Geophysique de l'Environnement (LGGE),
Grenoble, France invites applications for a post-doctoral position in
Modelling 20th Century trends of atmospheric trace gases using firn-air
data.
The position lasts one year, to commence the first semester 2004. The
successful applicant will be employed by Centre National de la Recherche
Scientifique (CNRS), with a monthly salary of about 2680 USD (2100
Euros) dependent on the experience of the candidate.
POSITION DESCRIPTION
In the frame of the European Commission 5th framework programme CRYOSTAT
(Cryospheric Studies of Atmospheric Trends in stratospherically and
radiatively important gases), we are seeking for a post-doctoral
researcher to interpret trace gas mixing ratio and isotope measurements
in polar firn air in term of atmospheric trends and budgets, using
atmospheric chemistry and firn air diffusion modelling.
Within the project, measurements of numerous halocarbon compounds, as
well as methane and CO isotopes are performed on polar firn air from
Antarctica and Greenland. Such measurements give access to historical
concentrations over the last 50-100 years (see for example Sturges et
al., JGR 106(D2), p1595, 2001).
In order to convert the concentration-depth profiles into temporal
trends, a model of trace-gas diffusion in firn air (Rommelaere et al.,
JGR 108(D25), p30069, 1997; Fabre et al., GRL 27(4), p557, 2000) is
used. The consistency of these trends with our knowledge of the species
budget will be tested using a 2D model of the lower and middle
atmosphere chemistry (Martinerie et al., JGR 100(D7) p14291, 1995) run
on a century time scale.
The first priority will be to produce best-estimate globalized trends of
about 20 halocarbon species. Further work will focus on modelling other
halocarbon species and/or isotopes of methane and CO and/or the impact
of halocarbons on the ozone layer.
The programming environment is linux/unix and fortran. A recent Ph.D.
graduate with experience in computer modelling, and knowledge in
atmospheric chemistry and/or trace gas budgets is desirable.
The successful candidate will work within the 'gas group' of LGGE:
