TL;DR: The authors of as discussed by the authors truly appreciate the funding provided by Nazarbayev University through the Collaborative Research Grant (grant number: 091019CRP2104), and they would like to acknowledge the resources provided by CART and EREC to conduct this research.

TL;DR: In this paper, the authors demonstrate that NPF in polluted environments is largely driven by the formation of sulfuric acid-base clusters, stabilized by the presence of amines, high ammonia concentrations, and lower temperatures.

TL;DR: In this article, the concentrations of neutral and charged sub-3nm clusters and their connection to new particle formation (NPF) were investigated during the PEGASOS campaign (7 June-9 July 2012) at the San Pietro Capofiume measurement station in the Po Valley, Italy.

TL;DR: In this paper, the authors used the cloud chamber to conduct nucleation experiments for the binary and ternary systems at temperatures from 208 to 248 K. Neutral monomer and dimer concentrations of sulfuric acid were measured using a CIMS.

TL;DR: The SMEAR Estonia data station as discussed by the authors provides a multitude of comprehensive continuously measured data covering key climatic and atmospheric characteristics (state and dynamics of solar radiation, trace gases, aerosols and air ions, meteorological parameters) and forest ecosystem traits (net primary productivity, individual tree growth, gas exchange characteristics, soil variables).
