Climate change as seen from space

René Garello, IMT Atlantique – Institut Mines-Télécom [divider style=”normal” top=”20″ bottom=”20″] [dropcap]T[/dropcap]he French National Centre for Space Research has recently presented two projects based on greenhouse gas emission monitoring (CO2 and methane) using satellite sensors. The satellites, which are to be launched after 2020, will supplement measures carried out in situ. On a global scale, this […]

Air quality: several approaches to modeling the invisible

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 processes and air pollution prevention. […]

Remote sensing explained: from agriculture to major disasters

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 possible through remote sensing. This […]

Particulate matter pollution peaks: detection and prevention

By Véronique Riffault, Professor of Atmospheric Sciences, IMT Lille Douai – Institut Mines-Télécom This article was originally published in French in The Conversation France. [divider style=”normal” top=”5″ bottom=”5″]   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 PM10 […]

Gasification, the future of organic waste recovery

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. Javier Escudero has been studying […]

Ocean remote sensing: solving the puzzle of missing data

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 fine-scale mapping of the homogeneous […]
