Method and apparatus to determine a planet vector

Edoardo Charbon, Herbert Shea, Renato Krpoun, Noémy Scheidegger

The present invention relates to a method for a low cost Planet vector Sensor based on imaging atmospheric oxygen emission at 762 nm or at 557.7 wavelengths using either CMOS, CCD or arrays of single photon avalanche diodes (SPADs). In both daytime and nig ...

Influence of El Nino-Southern Oscillation on the interannual variability of tropospheric ozone in the nothern midlatitudes

Isabelle Bey, Sylvia Generoso, Symeon Koumoutsaris

We use the GEOS-Chem model to interpret long-term measurements of tropospheric

{O}_{3}

and CO and to investigate the factors that contribute to their interannual variation (IAV) during the period from 1987 to 2005 with a focus on the northern mid-latitu ...

Traffic emission using floating car and sensor data

André-Gilles Dumont, Edward Chung, Emmanuel Bert

Air pollution is an important aspect for transportation, particularly car emission in urban area. The objective of this paper is to evaluate the global emission of a transport network based on probe car and traffic sensor data. This paper used the microsim ...

Understanding the origins and fate of air pollution in Bogota, Colombia

Erika Maria Zarate Torres

Bogota has more than 8 million inhabitants and is the 5th biggest urban agglomeration in Latin America. It has more than one million vehicles and a large number of small industries. High levels of air pollutants are thus detected. The purpose of this work ...

The EDC3 chronology for the EPICA Dome C ice core

Jérôme Chappellaz

Four halons (H-1301, H-1211, H-2402 and H-1202) have been measured in air samples collected from polar firn from Dome Concordia (Dome C), Antarctica, from Devon Island, Canada and the North Greenland Ice Core Project (NGRIP) site, Greenland. H-2402 and H-1 ...

Systèmes de communications à Ultra Large Bande

Pierre-André Farine, Cyril Botteron, Christian Robert, Frédéric Chastellain, Uroschanit Yodprasit, Paul Saad

Selon les normes de la FCC (Federal communications commision), un signal est considéré comme Ultra Large Bande (ULB) si la largeur de bande occupée est d’au moins 500 MHZ ou si la valeur de la bande relative est supérieure à 0.2. Par ailleurs, une communic ...

A model investigation of tropospheric ozone chemical tendencies in long-range transported pollution plumes

Isabelle Bey, Marion Auvray

The impact of continental outflow on the ozone chemical tendencies (i.e., production and loss rates) is quantified in the North Atlantic and northwest Pacific regions using the GEOS-Chem and the MOZECH global models of chemistry and transport. The ozone te ...

A global model study of ozone enhancement during the August 2003 heat wave in Europe

The European summer of 2003 was characterised by intense heat, prolonged isolation and suppressed ventilation of the boundary layer which, combined with large anthropogenic emissions and strong fires, resulted in a build up of an unprecedentedly high and l ...

Nitrogen and Sulphur Deposition on regional and global scales: a multi-model evaluation

We use 23 atmospheric chemistry transport models to calculate current and future (2030) deposition of reactive nitrogen (NOy, NHx) and sulfate (SOx) to land and ocean surfaces. The models are driven by three emission scenarios: (1) current air quality legi ...

Multi-model simulations of carbon monoxide: Comparison with observations and projected near-future changes

Isabelle Bey, Jérôme Drevet

We analyze present-day and future carbon monoxide (CO) simulations in 26 state-of-the-art atmospheric chemistry models run to study future air quality and climate change. In comparison with near-global satellite observations from the MOPITT instrument and ...
