Ozone Trend over Taiwan from TOMS Data

Ozone column data obtained from Nimbus 7 satellite instrument, TOMS, were analyzed. Total ozone data over Taiwan starts November 1978 till May 1993. Daily observations were changed into monthly data for trend analysis. First, spectral analyses were performed to find possible atmospheric movements. S...

Zusammenfassung:Ozone column data obtained from Nimbus 7 satellite instrument, TOMS, were analyzed. Total ozone data over Taiwan starts November 1978 till May 1993. Daily observations were changed into monthly data for trend analysis. First, spectral analyses were performed to find possible atmospheric movements. Significant peaks were found at periods of 6, 12, 19, and 29 months. The first two are due to seasonal variations. The last one corresponds to the quasi-biennial oscillation (QBO) in stratosphere. It is suggested that the 19-months period is the difference of the annual and the equatorial QBD frequencies.
