NOSA serves as a vital forum for Nordic aerosol scientists to meet, interact and plan research activities together. This has lead to several projects and research collaborations. A large number of Nordic research networks has been established from the NOSA activities since NOSA was founded in 1978. NOSA’s networking activities have been crucial in improving the quality of research and education within the Nordic community, bringing scientists together at least once a year in the respective NOSA symposia. NOSA symposia has been organised annually since 1978 and is a part of NOSA activities and fulfil several of NOSA’s objectives.

They bring together members of all aerosol research fields from most departments, institutes and research groups, not only form the Nordic countries but from all over the world. Last but not the least, NOSA symposia serves as small scale conferences where early career scientists can experience international conferences with oral and poster presentation in a relaxed environment. To encourage students to improve their presentation skills, a best student presentation award is given on the final day of each symposium, along with the NOSA aerosolgist award announced by the NOSA president at the conference dinner.
