Task 3.5: Validation of satellite-retrieved tropospheric O3 slant columns over selected Chinese and European stations that include ozone sondes.

First steps towards the validation process

a. Selection of ground-stations both from the WOUDC & AERONET networks.

b. Ground and satellite data availability c. Depiction criteria and general analysis

set-upd. And this should lead us up to the

Beijing Olympic Games of 2008!
