Airborne Demonstrator

The concept of CAIRT is based on the airborne demonstrator GLORIA that was successfully flown on a number of aircraft and balloon campaigns and is scheduled for further upcoming campaigns.


The Gimballed Limb Observer for Radiance Imaging of the Atmosphere (GLORIA) is a unique atmospheric remote sensing instrument that bridges the gap from scanning to imaging in the infrared spectral domain. This is realized by combining a classical Fourier transform spectrometer with a 2-D detector array. Imaging allows the spatial sampling to be improved by up to an order of magnitude when compared to state of the art limb scanning instruments. In addition to the limb mode the instrument can also perform nadir measurements. GLORIA is designed to operate on various high altitude research platforms on aircraft and stratospheric balloons.  The instrument is a joint development of the Karlsruhe Institute of Technology (KIT) and Forschungszentrum Jülich (FZJ).
