troposphere
- n the lowest atmospheric layer; from 4 to 11 miles high (depending on latitude)
- The bottom layer of the peel, the troposphere, is essentially where all global weather takes place; it extends from the earth's surface to a height of ten miles.
- The sun would heat the smoke and lift it into the stratosphere that's the layer above the troposphere, where we live where there is no rain to clear it out.
- Much of the soot in lower troposphere is eventually washed out by rain, but clouds higher up continue to block sun for weeks or months.
