Thanks!
Some precisions: the above maps are only those of the ZAMG (deutch weather site) dispersion model of the Iode-131 cloud.
Here you'll find many other great models (maps and animated maps)
such as:
* ZAMG: dispersion model
* Iode 131
* Xénon 133
* Césium 137
In these models, the colour scale shows a total of 5 colours. The area marked „E“shows an area with estimated current equivalent dose rate of 10
mSv/h (in a 25x25 km2 square). The violet colour on the outer edge of contaminated areas (Area A) represents 0,3 μSv/h, which corresponds to the
amount of the natural background radiation dose.
* EURAD: dispersion model
* Césium 137 surface
* Césium 137 2500m
* Césium 137 5000m
This animation displays a potential dispersion of the radioactive cloud (Caesium 137 Isotope) after a nuclear accident in reactor Fukushima I. The
continuous release rate is very uncertain, thus the calculations have to be interpreted qualitatively. Dispersion in the near surface level (Level 1),
in appr. 2500 m height (Level 12) and in appr. 5000 m height (Level 16).
* FLEXPART: dispersion model
* Iode 131
* Xénon 133
* Césium 137
These maps are avalaible for USA, Japan and Northern hemisphere and shows potential release based on recent analysis of the general stream
circulation, the radiations doses are shown in Bq/m-3.
* HYSPLIT: air parcel trajectories
* ensemble
* different heights
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.
