Total Ozone Column


Ozone (O3) is of crucial importance for the equilibrium of the Earth atmosphere. In the stratosphere, the ozone layer shields the biosphere from dangerous solar ultraviolet radiation. In the troposphere, it acts as an efficient cleansing agent, but at high concentration it also becomes harmful to the health of humans, animals, and vegetation. Ozone is an important greenhouse-gas contributor to ongoing climate change. Since the discovery of the Antarctic ozone hole in the mid-eighties and the subsequent Montreal protocol that regulated the production of chlorine-containing ozone-depleting substances, ozone has been routinely monitored from the ground and from space. For S5P/TROPOMI, there are two algorithms that will deliver total O3 column amounts to be retrieved from S5P/TROPOMI.
