Conclusions
3-4 successful flights of each payload LPMA/DOAS, MIPAS and TRIPLE
sophisticated flight planning strategies for ENVISAT matches
tropical measurements pending
long-term validation open
balloon data analysed
SCIAMACHY comparisons for O3, NO2, BrO (scientific retrievals)
pending: H2O, tracers
MIPAS-ENV V6.1 and FZK comparisons available
trajectory mapping powerful tool to improve validation
photochemical mapping for NO2 and BrO
