Abstract

Laboratoire de Physique Moléculaire et Applications (LPMA)/Infrared Atmospheric Sounding interferometer (IASI) balloon is a calibrated infrared Fourier transform spectrometer that is used to measure the Earth’s atmospheric emission (650–3000 cm<sup>−1</sup>). Operating under a stratospheric balloon, this spectroradiometer provides radiometrically calibrated spectra with an apodized spectral resolution of 0.1 cm<sup>−1</sup>, which can be used to retrieve the concentration of atmospheric trace gases such as H<sub>2</sub>O, CO<sub>2</sub>, CO, O<sub>3</sub>, N<sub>2</sub>O, and CH<sub>4</sub>. The radiometric calibration is performed by use of two reference blackbodies. A reference cavity (LPMA blackbody) has been developed to validate the radiometric calibration procedure and to characterize the instrument performances. One goal of the LPMA/IASI balloon is the preparation of the IASI mission, which is a satellite instrument dedicated primarily to operational meteorology. A description of the LPMA/IASI balloon, its performances, and the results obtained during the first flight of the instrument are presented.
