Surface ozone variation associated with rainfall

Using an electrochemical surface ozone recorder, continuous monitoring of surface ozone is being carried out at Trivandrum (8°29N, 76°57E). A study of those surface ozone data together with rainfall and temperature reveals certain variations in ozone associated with rainfall, apart from other established variations reported so far. While daytime rainfall brings a decrease in surface ozone, nighttime rainfall produces an increase. The change in the surface ozone persists for a longer duration than the rainfall.
