The regional distribution of tropospheric ozone in East Asia from satellite-based measurements
Abstract
Estimates of tropospheric ozone in the East Asian region were obtained using the TOMS and SAGE II satellite data sets through the application of residual analysis on a regional scale. The resulting tropospheric residual ozone shows seasonal variability with highest values in spring and summer. Latitudinal variations give indications of possible input to the tropospheric ozone column from anthropogenic activity. A strong correlation between residual and TOMS total ozone data during summer time suggests a significant level of photochemical ozone production in this region during this period. Comparisons are made with surface ozone measurements from remotely located sites in Japan and show a similar overall pattern.
