【 摘 要 】

Observations of O3and NO2have been performed in Kashgar, northwestern China, from January to December 2015. We analyze the variations of O3and NO2daily, the diurnal variations of O3and NO2as well as the relation between O3and NO2concentrations. We focused on the variations of O3, with the meteorological factors. We find that there exist to some extent between meteorological factors and O3concentrations. High O3concentrations were related to high temperature, low relative humidity, low cloudiness, and light wind speed. The local meteorological conditions on certain situations also influenced the ozone concentration. Preliminary statistics of the occurrence frequencies of high ozone concentration days corresponding to some meteorological factors are given in this paper.
