Interactive comment on “Envisat MIPAS

The paper describes a new retrieval technique for analysing MIPAS spectra based on (a) using a spectrally-averaged radiance, effectively synthesising a filter radiometer, and (b) using a band-averaged forward model, both of which represent significant differences from the approaches used by other groups (ie using measurements at their full spectral sampling and monochromatic forward models). Th...

Interactive comment on “Characterization of model errors in the calculation of tangent heights for atmospheric infrared limb measurements” by M. Ridolfi and L. Sgheri

This paper discusses causes of error in calculated tangent heights for IR limb sounders, with the work focussing on the MIPAS instrument on ENVISAT. Three causes of inaccuracy are investigated: 1) the refractive index of the atmosphere; 2) the ray tracing method; 3) the modelled atmosphere. The authors conclude that only the atmosphere used in the model has any significant effect on calculated ...

Interactive comment on “Measurements of Global Distributions of Polar Mesospheric Clouds during 2005–2012 by MIPAS/Envisat” by Maya García-Comas et al

General comments: overall quality of the discussion paper This study introduces and describes a PMC dataset from MIPAS IR emission observations, shortly presents the retrieval method that was already published in a previous paper, provides evaluation of its quality by comparison of MIPAS ice mass density and cloud altitude to AIM SOFIE observations, and discusses MIPAS cloud properties in relat...
