Tropospheric ozone distributions over Europe during the heat wave in July 2007 observed from infrared nadir spectra recorded by IASI
Résumé
First partial tropospheric ozone columns (0-6 km) derived from radiances observed by the IASI instrument aboard the MetOp-A platform over Europe during summer 2007 are presented. They were retrieved using an altitude-dependent regularization method. Comparison with measurements from balloon sondes shows excellent agreement. Space-borne observations show large lower tropospheric ozone amounts over SouthEastern Europe during the heat wave period, which are also displayed by simulations with a regional chemistry-transport model CHIMERE.
