TL;DR: In this paper, the 10-year observations of the atmospheric molar fractions of CO2, CH4 and CO in West Africa were analyzed using a high precision measurement of the Lamto (LTO) station (6°31 n and 5°02 n) in Cote...

TL;DR: In this paper , 20 years of CO2, CH4 and CO greenhouse gas atmospheric concentration measurements at the Finokalia station on Crete in the Eastern Mediterranean region are presented, based on bi-weekly grab sampling since 2002 and continuous observations since June 2014.
Relations source-récepteur transcontinentales identifiées avec un modèle Lagrangien de dispersion et une analyse en clusters Transcontinental source-receptor relationships identified with a Lagrangian dispersion model and cluster analysis
TL;DR: In this article, a Lagrangian particle dispersion model (LPDM) is used to calculate retroplumes that represent potential emission sensitivity (PES) for individual measurements, and the PESs can be grouped according to their similarities by using a clustering algorithm.
Posted ContentDOI
Quantitative evaluation of the uncertainty sources for the modeling of atmospheric CO 2 concentration within and in the vicinity of Paris city
TL;DR: In this article, a set of one-year forward simulations is carried out using the WRF-Chem model at a horizontal resolution of 1'km focusing on the Paris area with different anthropogenic emission inventories, physical parameterizations and CO2 boundary conditions.
Journal ArticleDOI

Rodrigo Rivera Martinez,Diego Santaren,Olivier Laurent,Grégoire Broquet,F.D Cropley,Cécile Mallet,Michel Ramonet,Adil Shah,L. Rivier,Caroline Bouchet,Catherine Juery,Olivier Duclaux,Philippe Ciais +12 more
TL;DR: In this article , the authors compared parametric and non-parametric models to reconstruct the CH4 peak signal from observations of the voltage variations of Figaro® Taguchi gas sensors (TGSs) in a laboratory experiment.
