Ozone production during the field campaign RISFEX 2003 in the sea of Japan: analysis of sensitivity and behaviour based on an improved indicator
Ozone production the field campaign RISFEX 2003 the sea of Japan an improved indicator
2010/10/21
The ratio Φ=kHC+OH[HC]/kNOx+OH[NOx] is used as an indicator for the sensitivity of ozone production (P(O3)) to HC and NOx in the field campaign RISFEX 2003 (RIShiri Fall EXperiment 2003) at Rishiri Is...
Impact of Manaus City on the Amazon Green Ocean atmosphere: ozone production, precursor sensitivity and aerosol load
Manaus City the Amazon Green Ocean atmosphere ozone production precursor sensitivity aerosol load
2010/10/11
We used a Single Column Chemistry and Transport Model (SCM) to infer the urban pollution emission fluxes of Manaus City, implying observed mixing ratios of CO, NOx and VOC. The model can reproduce the...
Sensitivity of a global model to the uptake of N2O5 by tropospheric aerosol
a global model N2O5 tropospheric aerosol
2010/8/16
The uptake of N2O5 on aerosol impacts atmospheric concentrations of NOx and so O3, OH, and hence CH4. Laboratory studies show significant variation in the rate of uptake, with a general decline in the...

We evaluate the effect of varying the temporal resolution of the input climate data on isoprene emission estimates generated by the community emissions model MEGAN (Model of Emissions of Gases and Aer...
Technical Note: Sensitivity of 1-D smoke plume rise models to the inclusion of environmental wind drag
1-D smoke plume rise models environmental wind drag Sensitivity
2010/2/1
Vegetation fires emit hot gases and particles which are rapidly transported upward by the positive buoyancy generated by the combustion process. In general, the final vertical height that the smoke pl...
