The Surface of the Sea is a Sink for Nitrogen Oxides at Night（图）
Nitrogen Oxides Sink Surface
2014/3/20
The surface of the sea takes up nitrogen oxides that build up in polluted air at night, new measurements on the coast of southern California have shown. The ocean removes about 15 percent of these che...

Trace gas Ozone Volatile organic compounds Black carbon Meteorology and oxides of nitrogen.
2016/3/25
The surface level ozone (O3), nitrogen oxides (NOx = NO2 + NO), volatile organic compounds (VOCs), black carbon (BC)
and meteorological parameters were continuously monitored for the period of one ye...
Ozone, carbon monoxide and nitrogen oxides time series at four alpine GAW mountain stations in central Europe
Ozone carbon monoxide nitrogen oxides four alpine GAW mountain stations central Europe
2010/12/28
Long-term, ground based in-situ observations of ozone (O3) and its precursor gases nitrogen dioxide (NO2) and carbon monoxide (CO) from the four sites Hohenpeissenberg and Zugspitze (D), Sonnblick (A)...
Nitrogen oxides and PAN in plumes from boreal fires during ARCTAS-B and their impact on ozone: an integrated analysis of aircraft and satellite observations
Nitrogen oxides and PAN boreal fires ARCTAS-B aircraft and satellite observations
2010/10/21
We determine enhancement ratios for NOx, PAN, and other NOy species from boreal biomass burning using aircraft data obtained during the ARCTAS-B campaign and examine the impact of these emissions on t...

Nocturnal nitrogen oxides a rural mountain-site south-western Germany
2010/8/12
A new, two-channel instrument for simultaneous NO3 and N2O5 monitoring was used to make the first comprehensive set of nocturnal NOx measurements (NO, NO2, NO3 and N2O5) at the Taunus Observatory, a r...
A case study of ozone production, nitrogen oxides, and the radical budget in Mexico City
ozone production nitrogen oxides radical budget Mexico City
2009/5/7
Observations at a mountain-top site within the Mexico City basin are used to characterize ozone production and destruction, nitrogen oxide speciation and chemistry, and the radical budget, with an emp...
The partitioning of nitrogen oxides between ice and air is of importance to the ozone budget in the upper troposphere. In the present study, adsorption of nitrogen oxides on ice was investigated at at...
