The percentage bias between MIPAS ozone data processed at IMK and those of five selected comparison instruments are small in the stratosphere. In the mesosphere (above 50 km) and in the tropopause region (10-15 km) the deviations are larger but also the agreement between the comparison instruments is far less pronounced there.
This validation study assesses both biases and the precision of the measurements. A large number of comparison instruments was involved: the satellite-borne instruments ACE-FTS, GOMOS, HALOE, HIRDLS, IASI, MLS, OSIRIS, POAM, SAGE II, SBUV, SCIAMACHY, SMILES, SMR; ground-based Umkehr measurements and the balloon-borne Mark IV spectrometer. Better agreement with reference instruments than for the previous data version is found: the known high bias around the ozone vmr peak is significantly reduced and the vertical resolution at 35 km has been improved.
