摘      要：Tropospheric ozone observations over China from 2005 to 2010 at three pressure levels (484,681 and 825 hPa) from the Tropospheric Emission Spectrometer on board the NASA Aura satellite have been *** Transform analysis revealed the trends and seasonality of regionally-averaged,monthly-mean ozone concentrations over western,northern and southern *** increases in ozone levels are found over all three regions at 464 hPa and the rate of increase is fastest over northern China,reaching 0.89±0.059 nL/(La).At 681 hPa,ozone shows increases over northern and western China,at a rate of 0.57± 0.065 nL/(La) and 0.41±0.041 nL/(La) respectively,but is constant over southern *** 825 hPa,ozone increases at a rate of 0.36±0.074 nL/(La) over northern China,while decreasing over southern China at a rate of 0.21±0.061 nL/(La).Over the three regions,ozone levels are generally higher in summer and lower in *** southern China at all three pressure levels and northern China at the 825 hPa level,ozone shows double peaks occurring in spring and autumn as a result of the combined effects of atmospheric chemistry and global *** work provides a useful observational dataset and tools for future analysis of changes in tropospheric ozone over China.
