DOI: 10.1002/qj.3475
Abstract: The magnitude of water‐vapour content and its temporal variability are factors that influence the thermodynamics of the atmosphere significantly and result in different meteorological phenomena or hazards. High‐quality observations of water‐vapour spatial and temporal distribution… read more here.
