The Answer is Blowing in the Wind

See the NASA video that shows how our weather can be monitored by tracking the aerosols in the atmosphere.

While this is of general interest, and you can only guess at the computer power required to produce this short video, the relevance to The Heather Trust's activities is in the large volume of smoke from the wildfires in Portugal in the western USA & Canada.  The area of the globe affected by this smoke is probably large enough to have an influence on weather patterns.

Another reason for taking the threat of wildfire seriously!
