A collection consists of several datasets that are in some way connected. They can belong to the same research series, research infrastructure, or come from the same research expedition.

We also provide access to the special collections “Swedish party programs and election manifestos” and the Swedish Gallup Institute's public opinion surveys from 1942 to 1956.

  • A four carbon organonitrate as a significant product of secondary isoprene chemistry

Oxidation of isoprene by nitrate radicals (NO3) or by hydroxyl radicals (OH) under high NOx conditions forms a substantial amount of organonitrates (ONs). ONs impact NOx concentrations and consequently ozone formation wh...
