Multi-annual changes of NOx emissions in megacity regions: nonlinear trend analysis of satellite measurement based estimates
NOx emissions megacity regions nonlinear trend analysis satellite measurement
2010/9/21
Hazardous impact of air pollutant emissions from megacities on atmospheric composition on regional and global scales is currently an important issue in atmospheric research. However, the quantificatio...
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...
Constraint of anthropogenic NOx emissions in China from different sectors: a new methodology using multiple satellite retrievals
anthropogenic NOx emissions different sectors methodology multiple satellite retrievals
2010/1/18
A new methodology is developed to constrain Chinese anthropogenic emissions of nitrogen oxides (NOx) from four major sectors (industry, power plants, mobile and residential) in July 2008. It combines ...
Evolution of NOx emissions in Europe with focus on road transport control measures
NOx emissions Europe road transport control measures
2009/3/13
European emission trends of nitrogen oxides since 1880 and up to present are presented here and are linked to the evolution of road transport emissions. Road transport has been the dominating source o...
Investigation of NOx emissions and NOx-related chemistry in East Asia using CMAQ-predicted and GOME-derived NO2 columns
NOx emissions NOx-related chemistry East Asia NO2 columns
2009/3/13
In this study, NO2 columns from the US EPA Models-3/CMAQ model simulations carried out using the 2001 ACE-ASIA (Asia Pacific Regional Aerosol Characterization Experiment) emission inventory over East ...
Technical Note: A diagnostic for ozone contributions of various NOx emissions in multi-decadal chemistry-climate model simulations
ozone contributions various NOx emissions multi-decadal chemistry-climate model
2009/2/26
Nitrogen oxide (NOx=NO+NO2) emissions from various sources contribute to the ozone budget. The identification of these contributions is important, e.g. for the assessment of emissions from traffic. Th...
Inversion of CO and NOx emissions using the adjoint of the IMAGES model
CO NOx emissions adjoint IMAGES model
2009/2/9
We use ground-based observations of CO mixing ratios and vertical column abundances together with tropospheric NO2 columns from the GOME satellite instrument as constraints for improving the global an...
