This is in regards to Armand Bayer’s letter about Take Down the Stacks, of the old PG&E power plant (July 1, 2021). As a weather observer of my own weather station office and service, I use the old power plant stacks for measuring ceiling and visibility for hourly observations. For example, if the cloud ceiling is 600 feet, the top of the smoke stacks would be 450 feet. The measuring of visibility is determined how far away the power plant is in miles, as well as the surrounding hills and mountains like for dense fog, and fog through stratus clouds.
In closing it would be a loss if this landmark were to be removed for meteorological reasons.
