Abstract
Nitrogen Oxide-03 photolytic cycle is dependent upon the presence of NO in ambient air. From our air monitoring observations we have found that the NO concentration in the atmosphere is often zero (0 to 5 ppb). This suggests a need to modify/change the photolytic cycle. Linear regression analyses on the O3 and NO2 concentrations in ambient air, measured in real time were carried out. The predicted values of O3 and NO2 from these regression equations were close to the observed values. On the basis of these two observations a modified photolytic cycle, including some other components (such as HONO2) is discussed.
