Analysis of seasonal and diurnal trends in surface ozone concentrations from Arctic research sites (Summit/Greenland; Barrow/Alaska)
Tropospheric ozone (O₃) is one of the most important atmospheric constituents. It is fundamental in determining oxidation processes in the atmosphere. It also severs as a major greenhouse gas, thus playing a key role in the energy balance of the atmosphere. Recent research had revealed springtime...
