Poster summary

• MAXDOAS measurements MAXDOAS _at_ ground and
  miniDOAS _at_200m height
• DSCD comparison highlight of a NO2 layer over or
  under 200m
• VCD comparison consistency with in-situ data
  (ground 200m)
• RTM and errors related to geometrical
  approximation for VCD (several geometries, NO2,
  aerosols loads)
• Satellite validation OMI and SCIAMACHY cloud
  issues for several retrieval schemes
