The destruction of ozone on ice surfaces was studied with an ice‐coated fused silica column used as a very long flow tube. Ozone destruction was found to be very slow. At 223 K and 258 K the measured reaction probabilities fall in the range 2 × 10 −8 ‐ 4 × 10 −10 , decreasing with increasing ozone concentration (20–1000 nbar). The observed kinetics are explained by an at least two step mechanism. The low reaction rates observed are insignificant for ozone destruction in cirrus clouds.
