What this source contributes.
Po Valley observations distinguish hydrated aerosol from activated fog droplets. Reported changes in inferred droplet counts follow classification choices, not an intervention that removed fog.

This is a bounded reading note. It is not independent replication, a full systematic review or an endorsement of every conclusion in the paper.
Questions to take to the paper
- Which wet sizes contribute most to attenuation?
- Does a change persist after temperature, humidity and inlet conditions are accounted for?
- Is the measurement representative of the volume people need to see through?
Keep the evidence attached to its setting.
A simulation, chamber result, field observation and operational outcome answer different questions. Record the comparator, measured quantity and conditions before carrying a result into a design.
