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−1). Operating under a stratospheric balloon, this spectroradiometer provides radiometrically calibrated spectra with an apodized spectral resolution of 0.1 cm−1, which can be used to retrieve the concentration of atmospheric trace gases such as H2O, CO2, CO, O3, N2O, and CH4. 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.
