Abstract : Radiation diagrams for atmospheric emission have been constructed for some single water vapor lines in the window region. The diagrams are based upon theoretical values for integrated line absorption and line width. By comparison of calculated with measured sky emissivities empirical integrated line absorptions can be derived. For this procedure the continuum background of sky emission must be accounted for. Continuum absorption coefficients have been obtained from measurements in narrow windows between water vapor lines from 8 tp 26 micron wavelength. In the 18.5 micron region the empirical integrated line absorptions came out smaller than the theoretical values, but the results are so far only based on a small number of measurements on Jungfraujoch.
