I thought chemtrails are basically contrails from aircraft, but if you are a conspiracy theorist they are supposed to be the poisonous gases realeased from aircraft to infect the population with some form of genocide, then the agency are meant to monitor the populace to see how they are affected.
I know there is supposed to be evidence from archived USA data that they did this on a small town approx 40- 50 years ago, but there is a large group around saying that the sky is fall of chemtrails and the govt is trying to kill us.
I not sure if this is what you are referring to Stormboy or if you have some other info, because I am curious.
