Farmers used to use smudge pots to create man-made cloud blankets that kept citrus trees from freezing.
Smudge pots produce heat which helps to keep citrus from freezing. The smoke is pretty much gone once the pot is 'primed'. After it gets about 29 or 30 degrees F, they don't work. (former Florida Citrus Belt resident)

I don't have personal experience with smudge pots but had read about the man-made cloud blanket effect long ago. Here is an entry at Encyclopedia Britannica
: smudge pot device - usually an oil container with some crude oil burning in the bottom, used in fruit orchards, especially citrus groves, to provide protection against frost. The smoke serves as a blanket to reduce heat losses due to outgoing radiation. Because of the air pollution they generate smudge pots have been generally supplanted by other means of frost protection, such as smokeless burners using natural gas.
