The MUSICA MetOp/IASI H2O and deltaD products: characterisation and long-term comparison to NDACC/FTIR data
Within the project MUSICA (MUlti-platform remote Sensing of Isotopologues for investigating the Cycle of Atmospheric water) ground- and space-based remote sensing as well as in situ data sets of tropospheric water vapour isotopologues are provided. The space-based remote-sensing data set is produced...
