East Palestine: Where did the prevailing winds take the contaminants?
NOAA HYSPLIT Model
You can run this model for any date and location. This is where some of the maps posted on social media originated.
East Palestine is 40.835N 80.525W
6-Feb-2023, 21:00 UTC (4PM EST), when they started the so-called "controlled burn"
Run for 24 hours, Release duration 24 hours, 750000 kg (750 tons approx.), 0 release bottom, 100m release top (values used for the maps posted on social media). Went with the defaults for everything else.
Note that the attached GIF only shows the first 24 hours (you can only run the model for 24 hours max). I understand it was burning until Feb 8.
Fixed incorrect start time on previous post.
