英文摘要	Using the daily data of TOMS (Total Ozone Mapping Spectrometer) from 1979 to 1994, the spatial and temporal variations of total ozone over East Asia (69.375 degreesE similar to 139.375 degreesE; 14.5 degreesN similar to 54.5 degreesN) and the west part of Europe (20.625 degreesW similar to 40.625 degreesE; 35.5 degreesN similar to 70.5 degreesN) were analyzed to make an intercomparison. Results showed that the mean ozone concentrations over the two regions similarly evolved in one year, with sinusoid curves which reached a maximum in spring (March for East Asia, April for Europe), and a minimum in autumn (October and November for East Asia and Europe respectively). With a higher annual mean concentration over Europe, the amplitude of seasonal variation was also larger in comparison to those of East Asia. Annual mean ozone concentrations showed obviously decreasing trends during the period from 1979 to 1994, over both regions, but the net reduction over Europe was approximately twice the amount as over East Asia. Spatial distribution pattern of total ozone showed clear differences over the two regions, as well as their seasonal evolution.; Engineering, Environmental; Environmental Sciences; SCI(E); CPCI-S(ISTP); 0
