AB  - Ozone (O(3)) decomposition in the troposphere is a very important process which 
      prevents excessive O(3) accumulation in the air. It is particularly significant 
      on warm summer days which are marked by a high risk of photochemical smog. We 
      used Spearman's rank correlation test to determine relationships between the drop 
      in O(3) concentrations over time (-DeltaO(3)), nitrogen oxide (NO), nitrogen dioxide 
      (NO(2)), and total nitrogen oxide (NO(x)) concentrations and meteorological 
      factors (1-h average) in low-polluted urban area in Olsztyn (north-eastern 
      Poland). Nitrogen oxide concentrations were measured continuously by the 
      chemiluminescence method, and O(3) concentrations were determined by the UV 
      photometric method. The obtained results suggest that the rate of decomposition 
      of tropospheric O(3) is affected mostly by the presence of NO(x), high 
      temperature, and air humidity (positive correlation) as well as by wind speed 
      (negative correlation). Maximum correlation coefficient values were reported 
      between -DeltaO(3) and air temperature, -DeltaO(3) and absolute air humidity when NO(x) 
      concentrations were low (below 1.0 microgram per cubic meter), reaching 0.271 and 
      0.243, respectively. These results indicate that O(3) also reacted with air 
      components other than NO and NO(2). Precipitation at average temperature of 
      < 0  degrees C did not significantly contribute to a drop in O(3) concentrations at 
      night-time. In the warm season, precipitation slowed down the rate of O(3) 
      decomposition, mostly because NO(x) were scrubbed by rain. An analysis of 
      seasonal and daily -DeltaO(3) fluctuations revealed that -DeltaO(3) values were highest 
      in the summer and shortly after sunset in the diurnal cycle.
