SUMMARY

12/06/2012 - Validation of ozone profiles, using ozonesondes

• GOME-2 ozone profiles are given as partial ozone columns on varying pressure levels (40 levels between surface and 0.01 hPa). Ozone partial columns are expressed in Dobson Units.
• Ozonesondes measure the ozone concentration with a vertical resolution of 100 m along the ascent until 30 km, which is much higher than GOME-2.
• The integration requires interpolation, as GOME-2 levels never match exactly ozonesonde layers. This interpolation causes negligible errors given the high vertical resolution of ozonesonde profiles.
