Peculiarities of distribution of gas impurities in clouds. Should they be taken into account in models?

According to the plane sounding, distributions of О 3, СО and СО 2 inside cloudy layers were examined. An increase in concentration of carbon oxide by 14.1±10.4 ppb and a decrease in content of carbon dioxide and ozone by 4.7±2.6 ppm and 11-15 ppb respectively were observed inside a cloud. Excess of CO and deficiency of О 3 and СО 2 in clouds having various forms was analyzed. Two possible mechanisms providing the excess of CO in clouds were proposed. The global contribution of phenomena under consideration was assessed. Estimates obtained showed that values of excess of CO and deficiency of О 3 and СО 2 were comparable with their global contents.
