Description

Tropospheric water vapour isotopologue ratios (expressed as δD) give unique insight into moisture sources and cloud processes, in particular if analysed together with the water vapour concentration. In this presentation we briefly introduce the theory of {H2O,δD}-pair distributions, present the recently published MUSICA IASI {H2O,δD}-pair data set (1.5 billion individual data points, offering twice daily global coverage for 10/2014 to 12/2020), document their potential for improving global atmospheric analyses, and present concrete examples of moisture studies over the West African monsoon region. We discuss the possibility for generating tropospheric water vapour isotopologue profile data by combining the two sensors IASI and TROPOMI.
