We present a validation of MIPAS-ENVISAT vertical profiles (ESA operational retrieval version 6.0) of N2
, CFC-12, and CFC-11. The geophysical validation is performed using data from a balloon-borne cryogenic whole air sampler and trajectory matching. We show that the validation results are different for the period prior to 2005 compared to the post 2005 period. N2
, and CFC-12 show partly good agreement while CFC-11 data from this retrieval cannot be used for scientific studies.
