Abstract:

We present a new version of O3 data retrieved from the three MIPAS observations modes of the middle atmosphere (MA, UA and NLC). The O3 profiles cover altitudes from 20 up to 100 km altitudes for daytime and up to 105 km at nighttime, for all latitudes, and the period 2005 until 2012. The data has been obtained with the IMK–IAA MIPAS level 2 data processor and are based on ESA version 8 re-calibrated radiance spectra with improved temporal stability. The processing included several improvements with respect to the previous version, such as the consistency of the microwindows and spectroscopic data with those used in the nominal mode V8 data, the O3 a priori profiles, and updates of the non-LTE parameters and of the nighttime atomic oxygen. Random errors are dominated by the measurement noise with 1σ values for single profiles for daytime of <5 % below ~60 km, 5–10 % between 60 and 70 km, 10–20 % at 70–90 km and about 30 % at 95 km. For nighttime, they are very similar below 70 km but smaller above (10–20 % at 75–95 km, 20–30 % at 95–100 km and larger than 30 % above 100 km). The systematic error is ~6 % below ~60 km (dominated by uncertainties in spectroscopic data), and 8–12 % above ~60 km, mainly caused by non-LTE uncertainties. ... mehr
