Ozone (O3) is of crucial importance to the equilibrium of the Earth's 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, though at high concentrations, it becomes harmful to human, animal, and plant health. Furthermore, ozone is a significant greenhouse gas contributing to ongoing climate change. The TROPOMI O3 total column product provides essential data for monitoring these atmospheric processes.
Key Features and Applications
The product delivers comprehensive information in NetCDF-CF format, including total ozone columns, ozone temperature, and diagnostic error information such as averaging kernels. By providing precise vertical column data, the product supports a wide array of research, from long-term climate monitoring to the assessment of regional air quality and health impacts.
