| Zusammenfassung |
| The erythemally weighted (UV) irradiance below the severely depleted Arctic
vortices in spring 1996 and 1997 were substantially elevated. On average the
UV increased 36 and 33% relative to the 1979-1981 mean assuming clear
skies from day 80-100 in 1996 and 1997, respectively. On clear sky days
large regions of the Arctic experienced maximum UV increases exceeding 70
and 50% on single days in 1996 and 1997, respectively. A minor fraction
of these increases are not anthropogenic and have a dynamical origin as seen
by comparison to 1982, when hardly any ozone depletion is expected. |
