Paper Abstract

The ERA-40 reanalysis ozone data sets provided by ECMWF are most widely used at present, in order to use the data more effectively and reasonably, a comparison analyses are done and the features are discussed between the ERA-40 reanalysis and Halogen Occultation Experiment (HALOE) Observations on Upper Atmosphere Research Satellite (UARS). The spatial and temporal variations of the differences between two ozone data are analyzed in detail. Signal-to-Noise Ratios are estimated firstly by HALOE observational ozone concentration in seasonal and interannual time-scales, respectively. The results indicate that there are significant seasonal and interannual variations in a large part of stratosphere. The comparison analysis suggests that seasonal variation in ozone from ERA-40 is similar to HALOE observations and interannual variation in ozone from ERA-40 is greatly weaker than that of HALOE observations in the tropical middle stratosphere, but is enhanced at low latitudes in the lower stratosphere.
