Popis: The final level-1b version of MIPAS spectral data, version 8, is the basis of the improved level-2 IMK/IAA research data product that covers all observations modes (NOM, UTLS, MA, UA and NLC) and consists of: temperature, O3, H2O, CH4, N2O, CO, HNO3, NO2, NO, HNO4, BrONO2, N2O5, PAN, ClONO2, ClO, HOCl, CCl4, CH3Cl, COCl2, COF2, COClF, CFC-11, CFC-12, HCFC-22, CFC-113, CF4, C2H6, C2H2, HCN, HCOOH, H2CO, CH3OH, CH3COOH, acetone, HDO, H2O2, O3P, heavy ozone isotopologues, 15N isotopologues of HNO3, N2O, and NO2, SO2, OCS, SF6, NH3, sulphate aerosol, ammonium nitrate aerosol, PSCs, PMCs, and CO2 (above 65 km).Improvements with respect to previous versions will be discussed. The data come on a constant fine vertical altitude grid and contain pressure, temperature, trace gas volume mixing ratios, vertical resolution and the diagonal of the averaging kernel matrix. An elaborate error estimation for each single profile, compliant with the SPARC TUNER initiative and described in von Clarmann et al. (2022, doi: 10.5194/amt-15-6991-2022), is provided. In addition, as an easy-to-use data product, the abundances of most of the retrieved trace gases are also provided on a coarser vertical grid (constant over location and time for an individual trace gas) for which the averaging kernel matrix transforms to a unity matrix. This presentation allows for a fast and direct comparison to model simulations. We present examples for temperature and several trace species, demonstrate the improvements against earlier data versions, and discuss a number of use cases.
