ACTRIS-Finland Symposium

National Aerosol, Clouds and Trace Gases symposium

25.11.2020, 09:00–13:00 EEST (GMT+2)

Note: This event was separate from the INAR National Network Seminar

ACTRIS-Finland and Finnish Association for Aerosol Research (FAAR) organized a virtual half-day seminar on Wednesday 25th November 2020 concentrating on observations of aerosol, clouds and reactive trace gases. The aim of the symposium is to facilitate networking and exchange of knowledge among groups working on similar topics at different institutes across Finland and increase knowledge about the ACTRIS infrastructure and what it offers for researchers.
