HFC-23 (CHF3) emission trend response to HCFC-22 (CHClF2) production and recent HFC-23 emission abatement measures
HFC-23 (CHF3) emission trend HCFC-22 (CHClF2) production recent HFC-23 emission abatement measures
2010/9/1
We present observations of lower-tropospheric mole fractions of HFC-23 measured by "Medusa" GC/MSD instruments from ambient air sampled in situ at the Advanced Global Atmospheric Gases Experiment (AGA...
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...
Refining temperature measures in thermal/optical carbon analysis
Refining temperature measures thermal/optical carbon analysis
2009/1/14
Thermal/optical methods have been widely used for quantifying total carbon (TC), organic carbon (OC), and elemental carbon (EC) in ambient and source particulate samples. Thermally defined carbon frac...
Simple measures of ozone depletion in the polar stratosphere
Simple measures ozone depletion polar stratosphere
2008/10/27
We investigate the extent to which quantities that are based on total column ozone are applicable as measures of ozone loss in the polar vortices. Such quantities have been used frequently in ozone as...
