Abstract

The aerosol and ozone mixing ratio data of HALOE is used to analysis the distribution and trends of the aerosol and ozone over the Plateau is analyzed and their relationship is discussed further. There is clear gap in the aerosol and ozone vertical profiles. Below the 50 hPa level the difference of the aerosol in different seasons is clear and the aerosol mixing ratio in winter and spring is more than that in summer and autumn. Between 20 hPa and 5 hPa, the ozone mixing ratio is highest in summer and lowest in winter. The ozone over the Plateau is less than that of ECHN in spring and summer from 100 hPa to 10 hPa so that these results in the ozone valley from May to July. In the low stratosphere from 100 hPa to 60 hPa and the upper stratosphere above 30 hPa, aerosol and ozone mixing ratio both have a good positive correlation over the Tibetan Plateau.
