MIPAS as a mesospheric instrument

Journal article

The mesosphere has not attracted much attention from the science community mainly due to a lack of instruments capable of sounding this region. MIPAS includes the lower mesosphere in its nominal scan mode and its altitude coverage can be extended well into the thermosphere by using special viewing modes. In this paper mesospheric spectra are analyzed from a calibration point of view although similar techniques can be applied to detect real atmospheric features. After applying spectral masks to remove atmospheric emission lines, large number of the remaining spectra are averaged to check the calibration of the forward and reverse offset and to validate the noise equivalent spectral radiance (NESR).
