Ozone in the stratosphere stops harmful ultra-violet radiation coming down to the Earth
There is an ‘ozone hole’ each year over Antarctica.
The photograph shows one of the largest ever ozone holes – it occurred on 24 September 2006
Blue and purple colours show where there is the least ozone.
Green and yellow show where there is more ozone.

In this activity you will suggest functions that could be used to model real data.
You will consider how well they do this.
