Estimation of Antarctic ozone loss from ground-based total column measurements
Antarctic ozone ground-based total column measurements
2010/8/16
The passive tracer method is used to estimate ozone loss from ground-based measurements in the Antarctic. A sensitivity study shows that the ozone depletion can be estimated within an accuracy of ~4%....

A multi-model analysis of vertical ozone profiles
A multi-model analysis vertical ozone profiles
2010/8/13
A multi-model study of the long-range transport of ozone and its precursors from major anthropogenic source regions was coordinated by the Task Force on Hemispheric Transport of Air Pollution (TF HTAP...
Are there urban signatures in the tropospheric ozone column products derived from satellite measurements?
urban signatures the tropospheric ozone column products satellite measurements
2010/8/13
In view of the proposed geostationary satellite missions to monitor air quality from space, it is important to first assess the capability of the current suite of satellite instruments to provide info...

Circumpolar measurements speciated mercury ozone and carbon monoxide the boundary layer the Arctic Ocean
2010/8/13
Using the Swedish icebreaker Oden as a platform, continuous measurements of airborne mercury (gaseous elemental mercury (Hg0), divalent gaseous mercury species HgIIX2(g) (acronym RGM) and mercury atta...
Intercomparison methods for satellite measurements of atmospheric composition: application to tropospheric ozone from TES and OMI
satellite measurements atmospheric composition tropospheric ozone TES OMI
2010/8/13
We analyze the theoretical basis of three different methods to validate and intercompare satellite measurements of atmospheric composition, and apply them to tropospheric ozone retrievals from the Tro...
