TL;DR: In this article, the authors show that biomass burning aerosols aloft strongly increase the low cloud coverage over both land and ocean in subtropical southeastern Asia, and the degree of this enhancement and its spatial extent are comparable to that in the Southeast Atlantic, even though the total biomass burning emissions in Southeast Asia are only one fifth of those in Southern Africa.

TL;DR: In this article, the authors showed that the difference between AAEs calculated using different corrections can lead to conflicting conclusions on the type of aerosol when using the same data set.
Journal Article
On the accuracy of ion measurements using a neutral cluster and air ion spectrometer
Robert Wagner,Hanna E. Manninen,Alessandro Franchin,Katrianne Lehtipalo,Sander Mirme,Gerhard Steiner,Gerhard Steiner,Tuukka Petäjä,Markku Kulmala +8 more
TL;DR: Wagner et al. as mentioned in this paper presented a survey of the state-of-the-art research work in the field of physics at the University of Helsinki and the Helsinki Institute of Physics.
Journal ArticleDOI
Observation of incipient particle formation during flame synthesis by tandem differential mobility analysis-mass spectrometry (DMA-MS)
Yang Wang,Juha Kangasluoma,Michel Attoui,Michel Attoui,Jiaxi Fang,Heikki Junninen,Markku Kulmala,Tuukka Petäjä,Pratim Biswas +8 more
TL;DR: In this article, a high resolution differential mobility analyzer (DMA) and an atmospheric pressure interface-mass spectrometer (APi-TOF) were used to observe incipient particle formation during flame synthesis.
