TL;DR: In this article, a weakening of the Southern Ocean carbon dioxide (CO2) sink since 1981 relative to the trend expected from the large increase in atmospheric CO2 is estimated, but their network of five locations is too small to be reliable.

TL;DR: In this paper, the authors assess the impact on trace gas mole fractions of the new physical parameterizations recently implemented in the atmospheric global climate model LMDz to improve vertical diffusion, mesoscale mixing by thermal plumes in the planetary boundary layer (PBL), and deep convection in the troposphere.

TL;DR: In this article, the first atmospheric in-situ CO 2 measurement network for Paris, the capital of France, has been operated with the aim of monitoring the regional atmospheric impact of the emissions out coming from this megacity.

TL;DR: In this article, high-resolution aerosol mass spectrometry measurements were conducted during a field campaign at Mace Head Research Station, Ireland, in June 2007, and the results corroborate that transport of volcanogenic sulphate and dust particles can significantly change the chemical composition and size distribution of aerosol over the North Atlantic Ocean and should be considered accordingly by regional climate models.

TL;DR: In this article, the authors present two methods for estimating methane emissions from a waste water treatment plant (WWTP) along with results from a measurement campaign at a WWTP in Valence, France.
