Research Engineer Position in Aerosol Remote Sensing

Location: CNRM, Toulouse, France Duration: 2-year contract (renewable)
Starting date: October-December, 2024

The CNRM laboratory (Météo-France/CNRS) is now looking for a motivated and
enthusiastic research engineer to contribute to our research activities in
remote sensing of atmospheric aerosols from the next generation of weather
satellites in geostationary Earth orbit. We are seeking someone with a
solid background in quantitative remote sensing, who will play an important
role in a forthcoming project aiming the development of the future EUMETSAT
aerosol satellite product from the new Meteosat Third Generation-Imager
(MTG-I) mission.
Geostationary satellites are essential for meteorology and climate studies,
thanks to their ability to observe the Earth several times an hour. This
high temporal frequency is particularly interesting for characterizing the
often rapidly changing aerosol particles, which are injected into the
atmosphere by human activities, volcanic eruptions and other sources
sensitive to climate change, such as forest fires and dust storms.
Geostationary satellites can provide unique information to better
understand aerosol diurnal-scale processes, which remain poorly understood
today and cannot be studied from traditional low Earth orbit satellites
providing only one or two images per day.
In December 2022, EUMETSAT launched its first MTG-I satellite, due to
become operational in 2024, succeeding the Meteosat Second Generation (MSG)
mission, in orbit since 2002. MTG-I is equipped with the Flexible Combined
Imager (FCI), which acquires advanced images of the Earth compared with
those taken by the Spinning Enhanced Visible and Infrared Imager (SEVIRI),
on board MSG. The first phase of the upcoming EUMETSAT-funded project aims
to develop a retrieval algorithm to monitor aerosol properties, mainly
optical depth, from FCI data, every 10 minutes. CNRM plans to achieve this
goal by building on the expertise it has acquired in recent years with
SEVIRI data (https://urldefense.com/v3/__https://www.icare.univ-lille.fr/projects/user-driven-__;!!KGKeukY!ylJajX9bRvxix5YzcLYXA1n6LFTAov5Kr9Ga7NLF4xico1MWNew9iOh9q26D17ZQce0k7BVyPTfbvToWInY3$

overcoming current retrieval limitations thanks to FCI’s new spectral
channels, among other improved sensing performances compared to SEVIRI. A
secondary objective is to assess the benefits of the obtained FCI aerosol
observations for numerical prediction using a chemical transport model.

The successful candidate:
• will contribute to the scientific evolution and technical adaptation of
the SEVIRI aerosol retrieval algorithm developed at CNRM to FCI data. The
main tasks will involve improving the aerosol type assessment and the
estimation of errors, as well as processing multiple FCI channels to
maximize the aerosol information content.
• will assess the new FCI algorithm by comparing the obtained aerosol
retrievals with reference data from ground-based stations and
state-of-the-art satellite products.
• will write technical documents and participate in meetings related to the
project.
• will collaborate with a team of scientists, research engineers, and
students from CNRM and other institutes (ICARE, LOA, EUMETSAT), working on
satellite remote sensing
and numerical prediction.
• will be encouraged to submit their work to peer-reviewed scientific
journals.

Requirements:
• Engineer or M.Sc. degree in a field related to satellite remote sensing.
The holding of a PhD is a plus.
• Expertise in quantitative remote sensing, geophysical data inversion,
atmospheric aerosols, radiative transfer in the visible/near-infrared
domain (expertise in all fields is not mandatory).
• Good programming skills (python, fortran, git, linux).
• Professional proficiency in English, with good written and oral
communication skills.
• Proven ability to work as part of a research team.

Practical aspects: The successful candidate will be based at CNRM, in
Toulouse, which is a dynamic city renowned for its research centers and
aerospace industry. A 1+1-year contract is offered, with the possibility of
renewal for up to 3-5 years based on performance and funding. The gross
monthly salary is around 3480 euros, including French social security and
partial reimbursement of Toulouse transport pass. This is a telework
eligible position, with a maximum of 2 days a week.
Application procedure: Interested candidates are invited to send their CV,
a motivation letter, and the contact details of two academic referees to
xavier.ceamanos@meteo.fr.
