Comparison of Ozone Variations from Model Calculations (OsloCTM2) and Satellite Retrievals (SBUV)
In this study we analyse temporal and spatial variations of columnar ozone amounts over the northern and southern hemispheres, and calculate the correlation coefficients between total ozone and the equatorial zonal winds at 30 and 50 hPa, which were used as indices to study the impact of the Quasi-Biennial Oscillation (QBO) on ozone. Monthly mean total ozone amounts derived from improved chemical transport model simulations (OsloCTM2), were used to compute monthly zonal means over 10° latitude zones for the period 1998–2009, and compared with respective solar backscatter ultra-violet (SBUV) satellite observations over the northern and southern hemispheres. The correlations between ozone variations from the OsloCtm2 model calculations, ozone from SBUV satellite retrievals and the QBO are presented for the northern, tropical and southern latitudes.
