Research on water vapor isotopologues with Fourier Transform Infrared Technique.
Development of methodologies envisaged to obtain vertical profiling of HDO/H216O, and corresponding validation and comparison with in-situ airborne and ground-based observations during the MUSICA remote sensing validation campaign were performed during 2014 and 2105. The project MUSICA (MUlti-platform remote Sensing of Isotopologues for investigating the Cycle of Atmospheric water, supported by the European Research Council within the Seventh Framework Programme (FP7/2007-2013/ERC Grant Agreement, nº 256961), has as main goal the generation of a highquality database in a global scale of tropospheric water vapour isotopologues (H216O y HD16O) from ground-based remote measurements (Fourier Transform InfraRed spectrometers, FTIR) and space -based platforms (Infrared Atmospheric Sounding Interferometer, IASI, on board the satellites EUMETSAT/MetOp -A and MetOp-B).
The Izaña Tesbed has played a very active role in MUSICA being the main station supporting different experiments. The results of this project will contribute to a better understanding of the different processes affecting the cycle of atmospheric water and its link to the energy balance at a global scale. Main results achieved up to now have been published by Scheepmaker et al. (2015), Wiegele et al. (2014), Dyroff et al. (2015), Schneider et al. (2015; 2016) and González et al. (2016).
