Description
The Changing-Atmosphere Infra-Red Tomography Explorer (CAIRT) is one of the two remaining candidate missions competing for implementation as ESA’s Earth Explorer 11. CAIRT aims to reveal, resolve, and unravel the complex coupling between composition, circulation, and climate in our middle atmosphere, by improving our knowledge of the chemical-dynamic-radiative interactions that govern our climate system. CAIRT, a Fourier Transform Spectrometer for infrared limb hyperspectral imaging, would provide continuous limb radiance measurements from the mid-troposphere to the lower thermosphere, at high spectral resolution and with unprecedented horizontal and vertical sampling. Leveraging an innovative tomographic retrieval approach, CAIRT would produce a unique three-dimensional dataset of numerous trace gases, temperature and aerosols across the entire middle atmosphere to the edge of space. With this, CAIRT would provide critical information on: (a) atmospheric gravity waves, circulation and mixing; (b) coupling with the upper atmosphere, solar variability and space weather and; (c) aerosols and pollutants in the upper troposphere and lower stratosphere. CAIRT would thoroughly explore and elucidate the role of the middle atmosphere in climate dynamics, forcing and feedbacks. It would firmly anchor this knowledge in a more holistic understanding of fundamental processes within the Earth system.
