L’Ineris (Institut national de l'environnement industriel et des risques) est un Établissement Public à caractère Industriel et Commercial (EPIC) et placé sous la tutelle du ministère chargé de l'environnement. Son effectif est de 580 collaborateurs environ dont les 2/3 sont des ingénieurs/docteurs, pour l’essentiel basés à Verneuil-en-Halatte (Oise). Le chiffre d’affaires est de 80M€. Le statut du personnel est de droit privé (convention collective de la chimie). Sa mission : Réaliser ou faire réaliser des études et des recherches permettant de prévenir les risques que les activités économiques font peser sur la santé, la sécurité des personnes et des biens ainsi que sur l’environnement. Travailler à l’Ineris, c’est l’opportunité de mettre en œuvre et développer ses compétences dans le cadre des missions de recherche et d’expertise pour le compte des pouvoirs publics et des industriels. Ces missions intègrent excellence scientifique et technique, maîtrise de la gestion des coûts et des délais, et activités de laboratoire ou de terrain. L’Ineris dispose de moyens d’essais de pointe, souvent uniques en France voire en Europe.
Nos atouts :
A Verneuil en Halatte (site principal) : Environnement de travail privilégié sur un site boisé de 40 ha accessible en transports en commun, à 40mn au nord de Paris.
Une navette “Ineris” au départ de la gare de Creil assure gratuitement le trajet jusqu’à notre site en 10 minutes.
L’Ineris dispose de 30 000 m2 de laboratoires et halles d'essais avec des équipements multiples et à la pointe de la technologie.
Parking clos et surveillé
Restauration subventionnée (ou ticket restaurant pour sites hors Verneuil)
Transports publics remboursés partiellement
Bornes de recharge pour véhicules électriques
Possibilité de télétravail (selon le type de poste occupé)
INERIS is a public institute conducting research and policy support under the auspices of the French Ministry in charge of Environment. The Atmospheric Modelling and Environmental Mapping Unit of INERIS develops and uses numerical air quality management tools in the framework of research activities, support to policy but also to address the needs of private companies, in France and beyond.
You will be part of our team dedicated to atmospheric modeling and environmental mapping. The team is performing studies and developing air quality tools to support public authorities or requests from private clients, in France or internationally. Air quality modeling is applied for exposure assessments (chronic or accidental), short-term forecasts, or long-term projections (prospective or retrospective) in support to decision making. The spatial scales covered may relate to an industrial site, an agglomeration, a country, or a continent (in Europe or beyond).
The expertise of Ineris in the field is acknowledged through a number of research projects or operational activities in support to policy stakeholders (French Ministry in charge of Environment, European Commission and Environment Agency, United Nations).
You will carry out studies and developments in data assimilation to improve air quality forecasts using satellite data within the framework of the European research project European CAMEO[1] (Copernicus Atmosphere Monitoring Service Evolution) and the French project ARGONAUT[2] (PollutAnts and gReenhouse Gases emissiOns moNitoring from spAce at high ResolUTion). The assimilation system developed and used at INERIS is an Ensemble Kalman filter, based on the CHIMERE chemical-transport model (co-developped by CNRS) integrated in the DART framework from the National Center Atmospheric Research (NCAR).
You mission will be :
- To lead intensive calculations of atmospheric chemistry modeling and development of data assimilation code over France and Europe. The system is automated and intensive parallel calculations are carried out on a supercomputer. Sensitivity analyzes will be conducted to quantify the impact of inventories of emissions resulting from inverse modeling in France.
- To perform data assimilation of Sentinel 5P data (retrievals/L2) already available for various trace gases such as NO2, SO2, O3, CO and HCHO. Synergy strategies have to be developed in order to jointly assimilate observations at the surface and in altitude.
- To realize Observing System Simulation Experiments (OSSE) assimilation of NO2 from Sentinel 4 to ensure the system's ability to process these large high-resolution data streams available after 2024.

- We are looking for a MSc or PhD with general knowledge of the physics or chemistry of the atmosphere. Experiences in modelling and in data assimilation are mandatory. If you are highly motivated to develop such system for air quality application, you will need some skills listed below:
- You have and will develop broad knowledge of scientific programming (high performance computing linux environment, fortran, python, bash) and ability to use and design numerical analysis tools.
- You will promote, in English, the results obtained by contributing to academic publications, oral communications, study reports, or even making the results available in open data.
- We will work in team to achieve scientific objectives of major research project.
