Stratospheric ozone changes during the first year of SBUV observations

Synoptic analyses of solar backscattered ultraviolet (SBUV) ozone data have been performed on a daily basis for the first year of Nimbus 7 operation, November 1978 through October 1979, at the standard pressure levels: 30, 10, 5, 2, 1, and 0.4 mbar. By combining these data with the daily NMC meteorological analyses of temperature and geostrophic wind at the same levels, elements of the ozone-temperature relationship as well as the horizontal eddy transports are examined. In particular, the existence of an upper stratospheric high-latitude ozone minimum in winter is discussed, and the eddy fluxes are found to play a significant role in this feature, mainly associated with stratospheric warming pulses. At the same time, monthly average quantities are examined, and standing eddy components are related.
