Observations of SO<sub>2</sub and NO₂ by mobile DOAS in the Guangzhou eastern area during the Asian Games 2010

For the first time it is shown from satellite observations that not only NO 2 concentrations in China but also NO x emissions in all Chinese provinces have been decreasing in the

The two main anthropogenic CO 2 fluxes are emissions from the combustion of fossil fuels and net emissions from land use change, the latter being largely driven by deforestation

Another impact of non-acyl peroxy nitrates is that they are a possible positive inter- ference to in-situ NO 2 measurements in the upper troposphere because the non-acyl peroxy

We report a new method for the simultaneous in situ detection of nitryl chloride (ClNO 2 ) and dinitrogen pentoxide (N 2 O 5 ) using chemical ionization mass spectrometry (CIMS)..

Similar discrepancies are found when using the HYSPLIT trajectory model at different altitudes (10–13 km) or the wind speeds and directions, actually measured on board of the

Column measurements can be used to quantify the emission flux/production rate from an area source by driving around the source or driving up- wind and downwind of that source area..

First, the longitudinal distributions of these species in January 2008 highlight strong variations of OClO and NO 2 (relative to the longitude) in the lower stratosphere: in the

chemical regimes/air masses based on observations of reac- tive nitrogen species and peroxy radicals made during the in- tensive field campaign MIRAGE-Mex (4 to 29 March 2006).. The
