Latest Satellite Ozone Maps
Each of the four ozone maps downloadable from here shows some representation of the stratospheric ozone levels in the northern hemisphere For this reason they compare well and are fairly consistent - the pattern of low ozone 'holes' and high ozone areas is plainly visibile in each of them The GOME map shows a three dimensional representation of the earth, centred on the Atlantic ocean in the Northern hemisphere. It is useful for seeing continuous changes in stratospheric ozone (represented according to colour) over North America, the Arctic, Europe and North Africa. On this map, levels in Central Europe, Asia and the Far East are not visible. The data scale runs from 200 to 400 dobson units. The other three maps show the northern hemisphere, centered on the North Pole from nadir-view. The OMI map shows values from under 100 to over 500 Dobson units, as does the NOAA BUV/2 map. The WOUDC map uses values from 100 Dobson units to over 600 Dobson Units and is therefore the best map for representing very high levels.
