Chlorine Nitrate (ClONO2) inline Animation

This movie shows a 3D model simulation of how chlorine nitrate (ClONO2) changes during a northern hemisphere winter in the lower stratosphere. At the start of the movie you see the chlorine nitrate get destroyed as the PSCs form. For a large part of the movie, you see nothing as the chlorine released when the chlorine nitrate was destroyed stays in its more active forms. But as sunlight returns to the polar night region over the Arctic we see the ClONO2 start to recover. This first happens around the edge of the polar vortex, and we the the now classic doughnut shape of the so-called 'chlorine nitrate collar'.
