Abstract

In order to develop a method for the retrieval of temperature and water vapor profiles from IR emission spectra, the Defence Research Establishment Valcartier (DREV) has recently acquired a new device referred to as the Double input Beam Interferometer Sounder (DBIS). This sounder has been conceived to match the needs encountered in many remote sensing scenarios. It is a portable device composed of a Fourier spectrometer and one or optionally two telescopes that measures the atmospheric emission in the IR region from 3 to 20 μm at a spectral resolution of 1 cm^-1and at any prescribed viewing angles. In the summer 1992, the DBIS has been deployed successfully in a series of field experiments, producing spectral data of good quality for a variety of sky conditions. These spectral data are now being utilized as a guide for the development of an optimized inversion algorithm
