dc.description.abstractThe relation between ozone and temperature in the upper stratosphere is used to estimate the drift in the solar backscatter ultraviolet (SBUP) spectrometer on Nimbus-7 and the linear trend in ozone from 1979 to 1986. It is shown that in the upper stratosphere, where ozone and temperature variabilities are coupled through temperature-dependent loss rates, the ozone sensitivity to temperature (percentage change for 1 K increase in temperature) varies within a factor of three over time scales from a few days to a few years. At 2 mbar, the ozone sensitivity to temperature (percentage change for 1 K increase in temperature) varies within a factor of three over time scales from a few days to a few years. At 2 mbar, the ozone sensitivity to temperature varies in the range of -0.6 to -1.7 per cent. Using this relation and the inferred temperature trend from the NMC analyses, the 8-year trend in ozone at 2 mbar is estimated to vary from about +3 to +4 per cent in the tropics to about -1 to -3 per cent at high latitudes. These trends appear to be characteristics of dynamical perturbations The globally averaged trend in ozone at 2 mbar appears to be close to zero in accord with a similar trend inferred from the Stratospheric Aerosol and Gas Experiment (SAGE) measurements as discussed in Ozone Trends Panel Report of R T Watson (National Technical Information Service, Springfield, VA 22161, USA, 1988). This study suggests that at 2 mbar, the SBUV measurements may have drifted by about 20 per cent from 1979 to 1986.en_US
