Monitoring for Aerosol Particle Growth and Chemical Composition During New Particle Formation Events Using Minaturized Lightweight Instruments

One of the major uncertainties in climate-change is the contribution of airborne particles. A major source of these particles is nucleation from gaseous pollutants. In order to implement the particle effects to existing models the process of particle formation by nucleation in the atmosphere needs to be well understood. This requires to employ a dense network of monitoring stations measuring particle formation processes.

Currently, only a limited number of stations have the necessary equipment for measuring small particles produced by nucleation in the atmosphere. MAGNUM aims to produce low-cost, lightweight, yet fast-response aerosol size spectrometers that can measure the size distribution of particles in less than a second. These instruments will allow ground observations of high spatial density as well as observations with Unmanned Aerial Vehicles (UAVs). MAGNUM is an RPF Excellence Project that has been officially launched on January 2nd 2019 and will end after 30 months on 30th of June 2021. The project will be carried out in collaboration with the University of Helsinki in Finland.
