Air quality: several approaches to modeling the invisible

qualité de l'air, modélisation, air quality, modeling

The theme day on air quality modeling (organized by FIMEA and IMT Lille Douai) on June 8 provided an opportunity for researchers in this field to exchange on existing methods. Modeling makes it possible to identify the link between pollution sources and receptors. These models help provide an understanding of atmospheric …

Remote sensing explained: from agriculture to major disasters

télédétection, remote sensing

There are numerous applications for remote sensing, from precision agriculture to helping with the deployment of aid in major disasters. Grégoire Mercier, a researcher at IMT Atlantique, explains the key notions of this remote observation method using examples from his research.   Detecting invisible objects from space… this is now …

SMART: radioactive expertise at the service of the environment

Radioactivity, SMART, IMT Atlantique

Nuclear power stations are not the only sources of radioactivity in France. Other sources undeniably include hospitals and the construction industry, for example. Given the potential dangers to health and the environment, such sites have to be permanently tested. SMART, a team of experts in radioactivity from SUBATECH is a …

Particulate matter pollution peaks: detection and prevention

Fine particulate matter pollution peaks, Véronique Riffautl, IMT Lille Douai

By Véronique Riffault, Professor of Atmospheric Sciences, IMT Lille Douai – Institut Mines-Télécom This article was originally published in French in The Conversation France.   This winter, France and a large part of Europe were struck by episodes of particulate matter pollution. These microscopic particles are known as PM2.5 and …

Gasification, the future of organic waste recovery

Gasification, Pilote, Mines Albi, VALTHERA, Javier Escudero

At a time when the challenge of waste recovery is becoming increasingly evident, gasification is emerging as a promising solution. The process allows organic waste to be decomposed into synthetic gas, which can be burned for energy purposes, or reprocessed to obtain gases of interest, such as methane and hydrogen. …

Ocean remote sensing: solving the puzzle of missing data

Ocean Remote sensing, data, IMT Atlantique

The satellite measurements that are taken every day rely greatly on atmospheric conditions, the main cause of missing data. In a scientific publication, Ronan Fablet, a researcher at Télécom Bretagne, proposes a new method for reconstructing the temperature of the ocean surface to complete incomplete observations. This reconstructed data provides …

Removing pollutants from our homes

Pollutants, Département SAGE, Mines Douai, Frédéric Thévenet, COV

Indoor air is polluted with several volatile organic compounds, some of which are carcinogenic. Frédéric Thévenet, a researcher at Mines Douai, develops solutions for trapping and eliminating these pollutants, and for improving tests for air purifying devices.   We spend nearly 90% of our time inside: at home, at the …

An ocean of environmental data to be processed

René Garello, Vigisat, Océan, Télécom Bretagne, Ocean

If nowadays we can detect icebergs along the route of the Vendée Globe, track and identify ships causing pollution from space, and define ecological corridors and reserves for the protection of animal species, it is largely thanks to stations which receive and process satellite images in real time, and the …
