5.3.2 Dispersion Conditions - Wind Speed
Average wind speed data is a readily available indicator for dispersion conditions.
Data are available from the notifications of time extensions for some areas, from the
WMO
8
and MARS datasets
9
of JRC
10
and through additional information from the
Member States. From Table
3
it can be seen that the figures obtained with MARS
25 km
25 km dataset are higher compared to the time extension data (except for
Koˇice).
