[Met-jobs] Postdoctoral position on the impact of volcanic gases and aerosols on the atmosphere

Dear all,
A postdoctoral researcher is sought to collaborate on the
VOLCPLUME French ANR-funded project : « Volcanic plumes: emission,
chemistry-transport and impact on the atmosphere and climate ».
The position should start around September 2017 and will be for a
fixed term of 2 years. The researcher will be based at the
Laboratoire d’Optique Atmosphérique (Université Lille 1/CNRS) in
the vibrant city of Lille (France) which is located one hour from
three european capital cities (Paris, London, Brussels).
The VOLCPLUME project, at the interface between volcanology and
atmospheric sciences, aims at better characterizing volcanic gas
and ash emissions using inverse modelling procedures that combine
ground and satellite observations of the volcanic plume with
chemistry‐ transport modelling. The primary objective of the
project is to provide a refined knowledge of source emissions at
high temporal resolution which will improve our ability to
forecast the atmospheric evolution of volcanic plumes and better
assess their short‐term impact on air traffic or air quality. On
longer term perspectives, this research should provide a refined
quantification of the budget and life cycle of volcanic
sulphur-rich aerosols, which represent a key forcing parameter for
global climate models.
The successful candidate will retrieve, for specific volcanic
case-studies, timeseries of volcanic SO2 emission flux and height,
at high temporal resolution, using inverse modelling techniques
exploiting various UV and IR spaceborne observations. Based on
this refined SO2 source and a panel of aerosol observations
(including spaceborne-, ground- as well as in-situ observations),
the life cycle of SO2 and sulfate aerosols within a tropospheric
volcanic plume will be investigated using chemistry-transport
modelling. The candidate will especially explore the impact of the
substantial sulfur-rich degassing of the long-lasting Holuhraun
eruption of Bardarbunga volcano (Iceland) on the atmospheric
chemistry of the Arctic Polar region. The impact of Etna degassing
on the Mediterranean troposphere over the last decade will be also
investigated.
The Laboratoire d’Optique Atmosphérique (LOA) is reknowned
internationally for its expertise in the field of atmospheric
observation and modelling. Researches of its about 70 members
focus on the study of aerosols of various types (originating from
desert, biomass burning, sea, urban pollution and volcanoes),
meteorological clouds, gases and the interaction of these various
atmospheric components with radiation. Hence, the LOA develops
multi-disciplinary and multi-scale (from particle to global
scales) researches which benefit from 1- an expertise in the
retrieval of multiple satellite observations covering a large
spectral range from UV to thermal IR and millimetric waves, 2- two
instrumental platforms equipped with a large panel of
active/passive remote sensing and in-situ instruments, 3- its
participation in international ground-based network observations
(LIDAR, sunphotometry, UV radiation), 4- an expertise in the
development of instruments for airborne observations serving as
spaceborne prototypes and 5- an expertise in modelling the
atmospheric dynamics from urban to continental scales.
A PhD in Atmospheric Sciences, Geophysics or related discipline
with experience in atmospheric chemistry-transport modeling is
highly desirable. Experience in inverse modelling would be an
advantage. A strong background in Unix/Linux environment is
required.
Salary is calculated in accordance with french public service
salaries, taking into account previous work experience.
Applicants should submit a cover letter, a curriculum vitae
including a list of publications and the name of 2 or 3
references.
