This study provides observation-based national estimates of CFC-11, CFC-12, CFC-113, and 1,1,1-trichloroethane emissions for the United States (US) and United Kingdom (UK) from municipal solid waste (...
Quantitative assessment of Southern Hemisphere ozone in chemistry-climate model simulations
Quantitative assessment Southern Hemisphere ozone chemistry-climate model
2010/2/21
Stratospheric ozone recovery in the Southern Hemisphere is expected to drive pronounced trends in atmospheric temperature and circulation from the stratosphere to the troposphere in the 21st century; ...
What caused extreme ozone concentrations over Cotonou in December 2005?
extreme ozone concentrations Cotonou
2010/2/1
This paper reports the first record of extreme ozone measurements in Africa. As part of the AMMA program, the ozone vertical profile recorded on 20 December over Cotonou presents exceptionally high oz...
Simultaneous coastal measurements of ozone deposition fluxes and iodine-mediated particle emission fluxes with subsequent CCN formation
ozone deposition fluxes iodine-mediated particle emission fluxes subsequent CCN formation
2010/1/18
Here we present the first observations of simultaneous ozone deposition fluxes and ultrafine particle emission fluxes over an extensive infra-littoral zone. Fluxes were measured by the eddy covariance...
Annual cycle of ozone at and above the tropical tropopause: observations versus simulations with the Chemical Lagrangian Model of the Stratosphere (CLaMS)
Annual cycle tropical tropopause Chemical Lagrangian Model Stratosphere CLaMS
2010/1/18
Multi-annual simulations with the Chemical Lagrangian Model of the Stratosphere (CLaMS) were conducted to study the seasonality of O3 within the stratospheric part of the tropical tropopause layer (TT...
Lightning NOx emissions over the USA constrained by TES ozone observations and the GEOS-Chem model
Lightning NOx TES ozone observations GEOS-Chem model
2010/1/18
Improved estimates of NOx from lightning sources are required to understand tropospheric NOx and ozone distributions, the oxidising capacity of the troposphere and corresponding feedbacks between chem...
A comprehensive evaluation of seasonal simulations of ozone in the northeastern US during summers of 2001–2005
