Silvia M. Short summary. The spatial and temporal restrictions of observations and oversimplified aerosol representation in large eddy simulations LES limit our understanding of aerosol—stratocumulus interactions. Kaikkonen, Eero O. The novel holographic imaging instrument ICEMET was adapted to measure the microphysical properties of liquid clouds, and these values were compared with parallel measurements of a cloud droplet spectrometer FM and particle measurements using a twin-inlet system.
When the intercomparison was carried out during isoaxial sampling, our results showed good agreement in terms of variability between the instruments. This agreement was confirmed using Mutual and Pearson correlation analyses.
We regarded the banana shapes in the surface plots as a special kind of object similar to cats and applied an instance segmentation technique to automatically identify the new particle formation NPF events especially the strongest ones , in addition to their growth rates, start times, and end times. The automatic method generalized well on datasets collected in different sites, which is useful for long-term data series analysis and obtaining statistical properties of NPF events.
Lehtinen, Douglas R. Worsnop, and Annele Virtanen. An aerosol mass spectrometer was used to characterize aerosol chemical composition during new particle formation periods. The time profiles of mass concentrations and chemical composition of observed aerosol particles are subjected to joint effects of boundary layer dilution, atmospheric chemistry and aerosol mixing in different boundary layers. During the nighttime, the increase in organic aerosol mass correlated well with the increase in condensed highly oxygenated organic molecules' mass.
