Abstract: [1] The newly reprocessed solar backscatter ultraviolet (SBUV) and Total Ozone Mapping Spectrometer (TOMS) version 8 data from 1979 to 2003 are used to estimate the seasonal cycle, latitude dependence, and long-term trends in ozone averaged over the Pacific region (120°W to 120°E) in three broad layers of the atmosphere: upper stratosphere (32 hPa and above), lower stratosphere (32 hPa to tropopause), and the troposphere. The ozone amount in these layers is derived by first determining stratospheric column oz…
