The hydroxyl radical, OH, initiates the removal of the majority of trace gases in the
atmosphere, and together with the closely coupled species, the hydroperoxy radical, HO2, is …

Ozone holds a certain fascination in atmospheric science. It is ubiquitous in the atmosphere,
central to tropospheric oxidation chemistry, yet harmful to human and ecosystem health as …

Concentrations of ground‐level ozone ([O3]) over much of the Earth's land surface have

The nitrate radical, NO3, is photochemically unstable but is one of the most chemically
important species in the nocturnal atmosphere. It is accompanied by the presence of …

The chemical complexity of atmospheric organic aerosol (OA) has caused substantial
uncertainties in understanding its origins and environmental impacts. Here, we provide …

In the present review we describe the emerging tendency for creating target-oriented
analytical approaches designed to solve important chemical tasks by using a combination of …

The hourly ozone (O 3) data from 332 background monitoring stations, spread in France,
were analyzed over the period 1999–2012 and short-term trends were calculated. In the …

The COVID-19 pandemic forced governments around the world to impose restrictions on
