1.1.5 Peculiarities of MIPAS

The three atmospheric sensors on board ENVISAT, GOMOS, MIPAS and SCIAMACHY not only represent a continuation of the atmospheric ozone monitoring mission GOME/ERS-2 but significantly enrich the scope of observational capabilities - mainly the number of detectable species and their vertical distribution - making use of a variety of novel measurement techniques and enhanced spectral coverage.

Figure 1.9 Spectral coverage provided by the three instruments.

Their three instruments' geophysical products will comprise a large number of atmospheric state parameters, primarily trace gas abundancies, and establish a high degree of complementarity in the provided information. Together, these data will supply the user community with unprecedent insights in the atmosphere's chemical and physical processes and facilitate major steps forward towards a better understanding of the future evolution of it's chemical and climatological balance.

The MIPAS instrument has been designed to acquire global measurements of the Earth's limb emission ranging from the upper troposphere up to the mesosphere. Analysis of numerous minor trace gases exhibiting spectral features in the 685 - 2410 cm-1 wavenumber interval (14.6 - 4.15 μm wavelengths) is envisaged posing challenging requirements on radiometric sensitivity, spectral resolution and pointing stability. MIPAS will provide accurate vertical profiles of atmospheric temperature and a number of key trace gases, including the entire NOy family (except NO3), and cover a height range from the upper troposphere up to the lower mesosphere. As MIPAS detects the atmosphere's thermal emission it is independent of sunlight conditions ('day & nightside' measurements) and provides global coverage.
