TL;DR: In this article , the response of atmospheric new particle formation to changes in the atmospheric chemical cocktail was examined and the main clustering process was unaffected by the drastically reduced traffic emissions, and the formation rate of 1.5 nm particles remained unaltered.

Nano Ranking Analysis: determining NPF event occurrence and intensity based on the concentration spectrum of formed (sub-5 nm) particles
Pauli Paasonen,Markku Kulmala,Tom V. Kokkonen,Diego Aliaga,Veli-Matti Kerminen,Simo Hakala,Santeri Tuovinen,P. Levin,Mette Lind Kusk,LIA DIETRICH,NMNH Division of Mammals,О.А. Казакевич,Nikolaus Werz,Patrick Schmidt +13 more
TL;DR: In this article , the authors introduced a new method, termed "Nano Ranking Analysis", for characterizing new particle formation (NPF) from atmospheric observations using daily variations of the particle number concentration at sizes immediately above the continuous mode of molecular clusters.

Martha A. Zaidan,Martha A. Zaidan,Ville Haapasilta,Rishi Relan,Pauli Paasonen,Veli-Matti Kerminen,Heikki Junninen,Heikki Junninen,Markku Kulmala,Markku Kulmala,Adam S. Foster,Adam S. Foster +11 more
TL;DR: In this article, the authors calculate and explore the mutual information between observed new particle formation (NPF) events and a wide variety of simultaneously monitored ambient variables: trace gas and aerosol particle concentrations, meteorology, radiation and a few derived quantities.
