Ozone hole 2008

This animation shows the evolution of the ozone hole above Antarctica for 2008, as measured daily by the SCIAMACHY satellite instrument. With a thinner ozone layer and a higher position of the sun in the sky more ultraviolet radiation will reach Earth's surface, as can be seen at the right hand side. The graph below shows the ozone loss in megatons, representing the amount of ozone which would be needed to fill up the hole to a standard value of 220 Dobson Units. More data and background information can be found on the TEMIS website: http://www.temis.nl/protocols/o3hole/

@atmosmovie, this is very detailed, where did you get the information?

@awire007 : The ozone hole data is processed from satellite observations at our institute (KNMI, Royal Netherlands Meteorological Institute), and is freely available from the TEMIS website. Please check also our daily updated twitter site on the upcoming ozone hole 2010 (search for ozonehole2010)

What is this? Flip the left one out for summer instead of winter? That is misleading. They have ozone levels higher in the antarctic winter than they do during their summer. There is no possible way this could be true. You expect me to believe the thinning of the ozone happened in the south pole during OUR winter in the northern hemisphere? Or am I reading this graph wrong?
