TL;DR: In this paper, the authors analyzed size distributions measured continuously at a boreal forest measurement site at Hyytiala, Finland between 1996 and 2003 and identified days when new aerosol particle formation was taking place as well as days when no formation was detected, removing days with ambiguous status.

TL;DR: In this article, the authors measured aerosol number size distributions within the particle diameter size range 8-400nm during the period from May 1997 to March 2003 in Helsinki, Finland and found that more than 80% of the number size distribution had three modes: nucleation mode (30nm), Aitken mode (20-100nm), and accumulation mode (90nm).

TL;DR: In this article, the authors presented and investigated the physical characteristics and size-fractionated emission rates of indoor aerosol particles during different activities in a house (naturally ventilated) located in Prague, Czech Republic.

TL;DR: In this paper, the authors investigated the annual and diurnal variation of the nucleation, Aitken and accumulation mode aerosol number concentrations in four different places, Helsinki, Hyytiala, Pallas and Varrio in Finland.

TL;DR: An algorithm to parameterize aerosol particle number size distributions with the multi log-normal distribution function is developed and evaluated and showed the following advantages: it is suitable for different types of aerosol particles observed in different environments and conditions, it showed agreement with the previous standard algorithm in about 90% of long-term data set, it is not time-consuming, particularly when long- term data sets are analyzed.
