Ozone Content Variability in the Atmosphere Above Nizhny Novgorord. Comparison of the Results of the Radiometric and Satellite Measurements, Reanalysis, and Numerical Simulation

Abstract

We compare the results of observations and numerical simulation of the ozone-content variability in the atmosphere above Nizhny Novgorod for the winters 2015 and 2016. The data of the local ground-based measurements and the MERRA reanalysis, the satellite data (SBUV device), and the numerical-simulation results are used. The analysis of the results demonstrates similar patterns of the ozone-content variability for all data sources. The stable altitude maximum in the middle stratosphere with the short-term intervals of ozone-density increase is observed. Using the numerical-analysis data allows one to estimate the influence of the photochemical and dynamic factors on the observed ozone-content variability in the winter months in the atmosphere above Nizhny Novgorod.
