Integrated water vapor above Ny Ålesund, Spitsbergen: a multi-sensor intercomparison
Water vapor is an important constituent of the atmosphere. Because of its abundance and its radiative properties it plays an important role for the radiation budget of the atmosphere and has major influence on weather and climate. In this work integrated water vapor (IWV) derived from the measuremen...
