Ozone measurements

Halley is famous for being the place where the ozone hole was discovered. In spring the ozone values values over Antarctica are low because of the action of  chlorine from CFCs. Halley has a very long, continuous and high quality record of ozone measurements,

Here is Jon Shanklin taking the first Ozone measurement at Halley VI, he has good claim to be the person who discovered the ozone hole and the machine he is using (called a Dobson) is the actual one that confirmed the low ozone values.
