High-resolution Fourier transform spectroscopy laboratory measurements of pure water vapour absorption are performed at temperatures from –9 to 15°С in the near-IR spectral region. As the result the water vapour continuum absorption is retrieved within 1600 (6.25 μm) and 3600 cm–1 (2.7 μm) absorption bands. Spectral features of the continuum retrieved at 15°С are in good agreement with known data. It is shown that different spectral peaks of the continuum have different temperature dependencies.
