原始语种摘要: Global measurements of atmospheric water vapour isotopologues aid to better understand the hydrological cycle and improve global circulation models.This paper presents a new data set of vertical column densities of H2O and HDO retrieved from short-wave infrared (2.3  µ m) reflectance measurements by the Tropospheric Monitoring Instrument (TROPOMI) onboard the Sentinel-5 Precursor satellite. TROPOMI features daily global coverage with a spatial resolution of up to 7 km×7 km . The retrieval utilises a profile-scaling approach. The forward model neglects scattering, and strict cloud filtering is therefore necessary. For validation, recent ground-based water vapour isotopologue measurements by the Total Carbon Column Observing Network (TCCON) are employed. A comparison of...
