Swollen ozone hole over South Pole   This forecast map of assimilated total ozone (in Dobson Units) for 9 September 2005 is made at the Royal Dutch Meteorological Institute by combining wind data from the European Centre for Medium Range Weather Forecasts (ECMWF) with direct ozone observations from the SCIAMACHY atmospheric instrument aboard ESA's Envisat. An operational atmospheric ozone forecasting service is available via the PROMOTE (PROtocol MOniToring for the GMES Service Element) consortium, part of the GMES Services Element.   ESA's ten-instrument Envisat environmental satellite has been observing the Earth for more than three years.
