A scheme of the SCIAMACHY
validation organisational structures set-up by SCIAVALIG (light orange)
and by ESA (pale blue). The validation scientists actually doing the work are supported
by both organisations, if they have an approved AO proposal for SCIAMACHY validation (green). (graphics: DLR-IMF and

CTP (cloud top pressure) and AAI (absorbing aerosol index). (graphics: KNMI and DLR-IMF) |

| Fig. 9-3 | Global
distribution of validation sites. Symbols and colour codes are as follows:
triangles = core validation station, blue = NDSC network, red = Russian/NIS M-124 network, purple = NDSC
and Russian/NIS M-124 network, green = no network, yellow square or envelope = balloon launch site. (graphics: DLR-IMF

flight tracks for the September 2002 (left) and February/March 2003
(right) SCIA-VALUE airborne campaigns. In red are the northern tracks (September 3-8, 2002 and February 19
– March 3, 2003) while the southern tracks (September 15-28, 2002 and March 10-19, 2003) are displayed in yellow. (graphics: DLR-IMF) |

| Fig. 9-8 | Difference
between the ozone columns retrieved from SCIAMACHY and from GOME with the same scientific algorithms.
The relative differences are displayed in colour, as a function of the
day since January 1st, 2003 (horizontal axis) and the latitude (vertical axis). Data is presented with a latitude resolution
of 1 degree and time resolution of 1 day. The colour scale represents the ratio (SCIAMACHY-GOME)/GOME in %. The SCIAMACHY
O3 columns are retrieved by KNMI. (image: H. Eskes, KNMI) |

| Fig. 9-9 | Tropospheric
NO2 column obtained by SCIAMACHY together with the Falcon flight track
in red showing where AMAX-DOAS measured almost simultaneously. In the inset tropospheric
NO2 columns from AMAX-DOAS are plotted versus those from SCIAMACHY. The SCIAMACHY tropospheric NO2 columns are retrieved
by IUP-IFE, University of Bremen. (image: Heue et al. 2005) |

| Fig. 9-10 | Intercomparison
of BrO vertical columns retrieved from GOME, SCIAMACHY and ground-based DOAS measurements at Harestua, Norway, 60°N, 10°E.
SCIAMACHY data products from the ESA NRT processor version 5.01 are shown together with scientific retrievals performed at BIRA-IASB. Airmass
factors used to convert slant columns to vertical columns are calculated using same atmospheric profiles in all cases. (image:

O3 profiles with their standard deviations (dashed lines) and errors (shaded areas) for 145 collocated

SCIAMACHY data. The SCIAMACHY O3 profiles are retrieved by IUP-IFE, University of Bremen. (image: Brinksma et al. 2006) |
