抽象。在对流层中/低层，{H2O，δD}对是水汽路径的良好替代物;然而，它们的观测，特别是使用遥感技术时，是具有挑战性的。MUSICA项目（用于调查大气水循环的同位素多平台遥感）通过将遥感与现场测量技术相结合来应对这一挑战。目的是从NDACC（Network for the Detection of Atmospheric Composition Change）的FTIR（Fourier transform infrared）光谱仪从地面测量的中红外光谱和MetOp卫星上的IASI（Infrared Atmospheric Sounding Interferometer）测量的热最低点光谱中反演校准的对流层{H2O，δD}对。本文介绍了MUSICA的最终产品，并讨论了NDACC/FTIR和MetOp/IASI {H2O，δD}数据对的特点和潜力。首先，我们简要地恢复{H2O，δD}对检索的特殊性。其次，我们表明，最终产品版本的遥感数据绝对校准相对于H2O和δD在亚热带测量的原位剖面参考，0和7公里之间。第三，我们揭示了从不同的遥感器获得的{H2O，δD}对分布是一致的，并允许不同的低/中对流层水分路径被识别与多年原位参考协议。第四，我们记录的可能性NDACC/FTIR仪器的气候研究（由于长期监测）和MetOp/IASI传感器观测昼夜信号在准全球范围内，具有高水平分辨率。第五，我们讨论了由于遥感产品的不完全处理而误解{H2O，δD}对分布的风险。
Abstract. In the lower/middle troposphere, {H2O,δD} pairs are good proxies for moisture pathways; however, their observation, in particular when using remote sensing techniques, is challenging. The project MUSICA (MUlti-platform remote Sensing of Isotopologues for investigating the Cycle of Atmospheric water) addresses this challenge by integrating the remote sensing with in situ measurement techniques. The aim is to retrieve calibrated tropospheric {H2O,δD} pairs from the middle infrared spectra measured from ground by FTIR (Fourier transform infrared) spectrometers of the NDACC (Network for the Detection of Atmospheric Composition Change) and the thermal nadir spectra measured by IASI (Infrared Atmospheric Sounding Interferometer) aboard the MetOp satellites. In this paper, we present the final MUSICA products, and discuss the characteristics and potential of the NDACC/FTIR and MetOp/IASI {H2O,δD} data pairs. First, we briefly resume the particularities of an {H2O,δD} pair retrieval. Second, we show that the remote sensing data of the final product version are absolutely calibrated with respect to H2O and δD in situ profile references measured in the subtropics, between 0 and 7 km. Third, we reveal that the {H2O,δD} pair distributions obtained from the different remote sensors are consistent and allow distinct lower/middle tropospheric moisture pathways to be identified in agreement with multi-year in situ references. Fourth, we document the possibilities of the NDACC/FTIR instruments for climatological studies (due to long-term monitoring) and of the MetOp/IASI sensors for observing diurnal signals on a quasi-global scale and with high horizontal resolution. Fifth, we discuss the risk of misinterpreting {H2O,δD} pair distributions due to incomplete processing of the remote sensing products.
