Short summary
We investigate the accuracy, precision and long-term stability of the MIPAS Envisat IMK/IAA CFC-11 (CCl3F) and CFC-12 (CCl2F2) products. For comparisons we use several data products from satellite, airplane and balloon-borne instruments as well as ground-based data. MIPAS Envisat CFC-11 has a slight high bias at the lower end of the profile. CFC-12 agrees well with other data products. The temporal stability is good up to ~ 30 km, but still leaves room for improvement.
