System
Cm-Hysplit for Nuclear Emergency Responses
The
computational system Cm-Hysplit (Customized Meteorology-Hysplit) is a
customized version of the well-known atmospheric model Hysplit of US NOAA, which has been extended appropriately to respond to the
operational needs of EEAE (the Greek Atomic Energy Commission). The system uses
for the prediction of trajectories, dispersion and deposition, the forecast
gridded meteorological fields provided by EMY (the Hellenic National
Meteorological Service). The data from EMY are provided every day with a
purposely developed automatic procedure.
Below is an
example of a 48-hours forecast of the trajectory (left) and ground deposition
of Cs-137 (right), following a hypothetical release on the arbitrary date of 8
March 2001.
