Abstract A four-dimensional model was designed to assimilate ozone for a one-year period from January to December 1999. The model has 1 ° x 1 ° horizontal resolution and is 18 sigma levels in the vertical from 10 hPa to the Earth's surface. This Eulerian advection scheme uses total ozone from the Total Ozone Mapping Spectrometer (TOMS), and the NCAR/NCEP Reanalysis 3-dimensional wind field to calculate the evolving structure function and determine the vertical distribution of ozone over the model levels. Initially, ozone climatology is used to calculate the structure function. In this paper, the focus is on tropospheric ozone. We have analyzed the spatial and temporal variability of ozone at different atmospheric levels, and looked at a specific high ozone event occurring in March 1999, documented by the Indian Ocean Experiment (INDOEX) field study. For this reason, the region selected from 30N to 30S and 40E to 110E, is the primary focus in the study. Tropospheric NOx data from the global 3D chemistry-meteorology model MATCH-MPIC is used to examine the correlation of NOx with the tropospheric ozone in this study.
