Ozone and Snow

Dr. Linnea Avallone, atmospheric scientist from CU in Boulder, Colorado invites me out on the ice to look for ozone in the snow. This is a big place and ozone exists only 15 parts per billion which sounds like our current national debt. To make their job easier, her students Lars Kalnajs and Sean Davis have designed and built a big box that sits on the snow and measures ozone. Sometimes the ozone disappears entirely and no one knows why so that’s why we’re here–to find the missing ozone. Very little physics has been conducted on snow here and the results of Lars’ experiments may help shed light (bad pun) on the the ozone hole above us. Stay tuned…..

    I am always able to smell when it is snowing some miles away. To me it has a distinct smell and it is very calming and pleasant.
    We recently found a very old gadget that when turned on would make ozone. I later realized that it smells like snow.
    So does snow make ozone?
    Thank you, Ro
