Cleaner air as a result of pandemic lockdown

During the first lockdown of the coronavirus pandemic, soot concentrations in the atmosphere over Western and Southern Europe almost halved. This is apparent from the comparison of two measurement campaigns carried out by ...

Particle phase chemistry enables soot to better seed clouds

Highly oxygenated organic molecules are a key component of atmospheric secondary organic aerosol. However, the origin and formation mechanism of highly oxygenated organic molecules with high unsaturation (HU-HOMs), remain ...
