You might need to use small droplets rather than pollen to get relevant results. The Ars Technica summary of COVID-19 might have a reference for that distance figure; IIRC it was based on the distance that most droplets travel before falling.

- londons_explore 7y agoBehaviour dramatically depends on droplet size. Fog can last many hours and blow many miles before dissipating.
- robocat 7y ago“Cloud, fog and mist droplets are very small. Their mean diameter is typically only 10-15 micron (1 micron = 1/1000 mm) but in any one cloud the individual drops range greatly in size from 1 to 100 micron dia.“ Fog also has very high humidity (otherwise it would evaporate), so any study that shows lower transmission of the virus in high relative humidity environments has relevance to anyone that assumes droplet evaporation matters? https://www.accuweather.com/en/health-wellness/new-study-says-high-temperature-and-high-relative-humidity-significantly-reduce-spread-of-covid-19/703418 https://www.accuweather.com/en/health-wellness/new-study-say... So fog is very relevant, thanks.
