Measured in number of students and teachers, the Faculty of Science at the University of Helsinki is the largest science faculty in Finland. There are some 6,000 students taking a basic degree. Out of them, some 1,000 are postgraduates. There are some 500 international students, and over 200 researchers and teachers from abroad.
Institute for Atmospheric and Earth System Research (INAR) is a multi- and interdisciplinary research unit based in physics, chemistry, meteorology, forest sciences, environmental sciences and social sciences in the University of Helsinki. INAR aims to strengthen the internationally leading, integrated multidisciplinary research and education environment for atmospheric and Earth system science and to feed in scientific results for the national and international environment and climate policy. It performs multiscale research from molecular to global scale and focuses on climate change, air quality, biogeochemical cycles and ecosystem processes.
This project is in collaboration with Airmodus Ltd. Airmodus develops, manufactures and sells instruments and sampling systems for counting of airborne nanoparticles. Unique 1 nm measurement solutions to universities and research institutes; niche R&D and certification instruments for vehicle, industrial engine and aftertreatment industries for the measurements of emissions (e.g. EURO 6 certification or break emissions); and aerosol particle monitoring systems for research-oriented air quality authorities. Airmodus is a Finnish Helsinki based SME with global customers. For more information about Airmodus please visit

Faculty of Science invites applications for
