What is the biggest difference in oxygen content between rainy and sunny days?

The water vapor content in the air is high in rainy days, but the content of pollutants such as dust and harmful gases in the air will be much lower after being "washed" by rain.

In sunny days, sunlight can disinfect the air, so there are fewer viruses and bacteria in the air. With strong photosynthesis, plants give off more oxygen.

So sunny days after rain are the best.
