Over the past few days, I've been watching via Zoom.earth and Windy.com this strand of brown and attempting to figure out if it was from the fires on the US west coast or elsewhere. I'm here in PHX and there's been a consistent grey cloud/haze deck up at least 5-10k ft above ground. In the attached zoom.earth snap, there's a large upper level low circulating in the NE Pacific about 3000 km west of SFO, and it appears to be pulling this brown haze toward it. Is there anyone here who can venture an educated opinion on what this is, and where the sources of brown are?
