My research interests cover wide areas in the field of atmospheric aerosol science, including aerosol-trace gas and aerosol-cloud interactions as well as air quality-climate interactions and feedbacks. My favorite research tools, or approaches, are theoretical analysis, process modeling and interpretation of field measurement data. I am a co-leader of the Aerosol-Cloud-Climate-Interactions guidance group, and one of the Lead Authors of the chapter “Clouds and Aerosols” in the latest IPCC report on Climate Change 2013: The Physical Science Bases.
My main research interests are in atmospheric aerosol formation, anthropogenic aerosol emissions and their climate effects. I work between experiments and large scale models, producing parameterisations from existing measurements, analysing comprehensive multi-variable data sets, and comparing data sets from different parts of the world to each other and to model results. I am a co-leader of the Aerosol-Cloud-Climate-Interactions guidance group and the coordinator of the Doctoral Programme in Atmospheric Sciences at the University of Helsinki.
I am, generally, interested in Air Quality but have a wide interest about aerosols and their sources, transformation, and fate. Exposure is the ultimate goal in my research and within an international network of collaboration I am trying to develop models aiming at forecasting Urban Air Quality and assess the personal exposure (both indoors and outdoors). I am currently a Visiting Professor at the Institute for Atmospheric and Earth System Research but I am also a Professor of Physics at the University of Jordan.
I am a post-doctoral researcher with scientific interests in aerosol processes and their climatic effects, as well as meteorology in polar regions. Especially I’m interested in understanding different feedbacks in the Arctic and Antarctica. I strive to combine the small aerosols to large-scale meteorological phenomena in order to understand the interactions and connections between aerosols and changing climate. I have been teaching and assisting courses both in meteorology and aerosol physics at the university and enjoy sharing information about climate change to students and teachers at different educational levels ranging from kindergarten to high school.
Particulate air pollution has severe impacts on human health. Studying the sources contributing to the aerosol burden is an essential part for mitigating these effects. I am interested in the origin, sources and formation processes, of the secondary organic aerosol which contributes to the particulate matter in strongly polluted regions.
My scientific interests are environmental feedback loops (photosynthesis-aerosol-solar radiation interaction) and theoretical models of atmospheric aerosol dynamics.
I am a post-doctoral researcher with interest in atmospheric aerosol dynamics. My main research topic is atmospheric new particle formation which I study by (1) analyzing data from field and laboratory experiments and (2) simulating the dynamics of atmospheric molecular clusters.
My research focuses on the interaction and exchange between the biosphere and the atmosphere. I aim to gain new insights into how various types of vegetation affect the atmosphere. I do this by investigating (1) the drivers for both induced and constitutive production and emission of biogenic volatile organic compounds, (2) how these emissions influence the chemical composition of the atmosphere, and (3) the formation and growth of atmospheric aerosol particles in forested areas. My preferred tools include both simple parameterisations and extensive process-based biosphere-atmosphere models - both which I develop and utilise in strong relation to field observations.
I am a post-doctoral researcher focusing on applying machine learning on big atmospheric data. My research interests include machine learning for automating the determination process of aerosol particle formation days, information theory for improving scientific understanding of the relationship between atmospheric variables and developing data-driven modelling for atmospheric process.
I am interested in new particle formation events in various locations globally, as well as CLOUD chamber experiments at CERN. I like traveling, good coffees and french fries.
I am a PhD student focusing on risks of energy production in Finland. My work includes life cycle analysis for different ways to produce energy but also takes into account people and risks that they face during the entire life cycle. I'm also secretarial science at Future Earth Finland which is a national committee for global chance research. I teach career courses for physic students and have a lot of interests science communication.

I'm interested in winds, vertical velocity and variations in them because we can use them to calculate turbulent properties which, in turn, help in understanding the different mixing processes within the boundary layer. I work mainly with Doppler wind lidars and develop applications and methods for them to study the boundary layer.
I am a PhD student looking at the early stages of atmospheric new particle formation mainly with the use of ion spectrometers. I am also involved in the the Pan-Eurasian Experiment Project (PEEX) communications activities. My personal interests are on science communication! Particularly climate and environmental science communication should be accesible to all, if we really want to codesign solutions for the challenges we are facing!
I am a PhD student working with aerosol particles in the atmosphere, particularly over boreal forest in Finland, and their climatic effects. I use airborne in situ measurements and ground-based high spectral resolution lidar observations to investigate behavior of the aerosols in the boundary layer and in the elevated layers. I am also interested in satellite remote sensing of aerosol particles and trace gases, as well as atmosphere-biosphere interactions. My hobbies are hiking, volleyball and dancing.
I am working on documenting and improving the data processing of the SMEAR measurement stations. I am also interested in the applications of machine learning methods in atmospheric sciences.
I study aerosol-cloud interaction in boreal forest domain using ground-based remote sensing such as cloud radars and lidars. I also have experience working with satellite data. In my free time I dance vogue and do photography.
My main focus is on air ions. I study how variations in natural ionising radiation levels are related to the properties of charged clusters and particles in the ambient air. My current approaches are based on the ion balance method. My work consists of both ambient observations and theoretical development. I am also interested in ionising radiation and air ion measurements. As side paths, my studies are additionally oriented towards the investigations of atmospheric electricity and boundary layer stability.
I'm working with the global aerosol-climate model ECHAM-HAM. My work consists of developing new emission modules, model evaluation, and model application to various natural and anthropogenic scenarios. In more detail, I focus on the modeling of submicron particle number and cloud condensation nuclei concentrations derived from anthropogenic sources.
I'm currently working on my master's thesis which is about new particle formation and shrinkage events in Saudi Arabia. I did my bachelor's on the growth of sub 3 nm particles in CLOUD 4 -experiments. Other than that, I have been doing NPF event classification for Hyytiälä.
My research interests are in field of satellite remote sensing, new particle formation, feedback in the climate system. For my master's thesis, I am working on feedback loop based on satellite data. I am currently a second year master student in Atmospheric science at university of Helsinki. Also, I am working as a research assistant in university of Helsinki.
I am a master student working mainly on the growth of atmospheric aerosol particles. As my main project this far, I have developed a programme that detects particle growth rates from size distribution data automatically for all size ranges from 3 to 1000 nm.
At the moment I am writing my master’s thesis about the correlation between different types of radiation and planetary boundary layer height. I am using measurement data from the SMEAR II station in Hyytiälä, where I have been working during this summer. The aim of my master’s thesis is to make a proxy for boundary layer height using measured radiation and other meteorological parameters. My main interests in meteorology are boundary layer processes and air quality.
My research is focused on atmospheric aerosol formation and new particle formation, particularly analysis of field measurements. Specific topics I am currently working on are the role of amines and organic compounds in new particle formation and sensitivity analysis of our measurement devices.
I am a master student at the University of Helsinki doing meteorology as my major. My main interests lie between micrometeorology and aerosol physics. I am keen on direct and indirect climate effects of aerosols, but also on their atmospheric transportation and new particle formation. At the moment my focus is to estimate the CO2-induced climate feedback in subarctic region. Furthermore, event classification analysis, mainly from SMEAR I station, is my liability.
