Fukushima I Nuclear Power Plant - cloud spread - air parcel trajectories
While this is a NOAA model, it is not a NOAA product and has not been seen or commented on by NOAA.
Extreme care should be taken with an awareness that the used HYSPLIT forecast was developed mostly for long-range transport purposes. Furthermore the amount of radioactive material emitted has not been quantified. It should also be noticed that local surface winds are largely effected by topography and structures therefore, wind patterns near the ground are likely to be different from synoptic scale patterns.
