First quantitative bias estimates for tropospheric NO₂ columns retrieved from SCIAMACHY, OMI, and GOME-2 using a common standard

Error estimates for BrO and SO 2 vertical column densities for the two lines of sight during the observation of the plume (Sect.. Overview of the retrieved BrO and SO 2 mixing

In order to achieve these objectives, we have first compared the daily maxima of ground ozone concentrations simulated by CHIMERE for summer months of 1997 and 2001 with

Outside the winter season, collocated satellite and ground-based measurements show higher NO 2 columns at 10:00 than at 13:45. In winter, the observed ratios

The present study aims at estimating the accuracy of the inferred vertical profiles of stratospheric O 3 and NO 2 by comparison to the corresponding data retrieved from tra-

Similar discrepancies are found when using the HYSPLIT trajectory model at different altitudes (10–13 km) or the wind speeds and directions, actually measured on board of the

The stratospheric vertical columns derived from SCIA- MACHY limb measurements and Oslo CTM2 simulations differ considerably from total vertical columns obtained over the clean

The red points correspond to the tropospheric column-averaged CH 4 mole fraction derived from N 2 O and explicitly using tropopause pressure, the blue to those derived from N 2 O

Vertical and slant tropospheric NO 2 -columns from the new satellite instrument SCIA- MACHY on ENVISAT are validated by measurements of the Airborne Multi AXis DOAS
