Schematic overview of the conventional infrastructure for NPF event detection and description contrasted with the proposed infrastructure.
Figure 3
Fetching and visualizing particle size distribution data in Jupyter notebook for April 4, 2013 at Hyytiälä. The colour indicates the particle concentration level (cm–3). The experts are interested in the yellow (white in grayscale) shape that reflects a NPF event for aerosol with particles of initially small but growing in diameter size.
Figure 4
Recording information about the event that occurred on April 4, 2013 at Hyytiälä. It is a very clear and strong event (Class Ia) during which new particle formation was observed to start at 10 am and end at 12 pm.
