Abstract

The trends of water vapor and methane in the stratosphere have been analyzed by using the HALOE data from 1992 to 2005. The variations of water vapor and methane averaged along latitude circle are analyzed in the levels 2hPa, 10hPa, 30hPa and 80hPa, which are taken as the upper, middle and lower stratosphere. Besides the seasonal and inter-annual variations, The trends of water vapor and methane in various levels are not the same. The variations of water vapor and methane generally are contrary. In the years when the water vapor increases, the methane decreases, and when the water vapor decreases, the methane increases.
