Abstract:

Measurement of the near-infrared water vapour absorption is made in the spectral region 2000–8000 cm–1 at a temperature of 287 K on the basis of high-resolution Fourier spectrometry. The water vapour continuum absorption spectrum is retrieved using known absorption in 2500 cm–1 region as a reference point. It is shown that in the conditions under investigation the continuum absorption in four windows differ no more than by 20%. This is in contradiction with MT_CKD continuum model that predicts much stronger variability of the continuum in these windows.

Keywords:

H2O continuum, MT_CKD continuum, atmospheric windows, FTS spectroscopy
