Short summary
The amplitude, the temperature dependence, and the physical origin of the water vapour absorption continuum are a long standing issue in molecular spectroscopy with a direct impact in atmospheric and planetary sciences. Using highly sensitive laser spectrometers, the water self continuum has been determined with unprecedented sensitivity in infrared atmospheric transparency windows.
