摘要：
Total Ozone Mapping Spectrometer (TOMS) instruments have been flown on NASA/GSFC satellites for over 20 years. They provide near real-time ozone data fur Atmospheric Science Research. As part of preliminary efforts aimed tu develop a Lidar station in Nigeria for monitoring the atmospheric ozone and aerosol levels, the monthly mean TOMS total column ozone measurements between 1979 to 1999 have been analysed. The trends of the total column ozone showed a spatial and temporal variation with signs of the Quasi Biennial Oscillation (QSO) during the 20-year study period. The values of the TOMS total ozone column, over Nigeria (4-14 degrees N) is within the range of 230-280 Dobson Units, this is consistent with total ozone column data, measured since April 1993 with a Dobson Spectrophotometer at Lagos (3 degrees 21'E, 6 degrees 33'N), Nigeria.
