Assessment of H2O Line Intensities: Future Work & Calibration in Atmospheric Research

Explore the assessment of water line intensities in atmospheric research, focusing on Camborne and Jungfraujoch. Discuss ongoing work, future ideas, and fitting parameters. Details on absolute calibration and progress at each site are highlighted for comparison and improvement.

  25. Future Work • Assessment of Line Intensities • Camborne • Completed; retrieved “a” are consistent with previous work • Jungfraujoch • Work has began; will be fairly quick with confirmed water profiles. Initial results are quite promising • Write up • Already began writing this up as a paper.... • Absolute Calibration • Camborne • On going work; need to think in some detail now what is causing difference between model and observations (line lists, continuum model, Kurucz , water profiles.........) • Jungfraujoch • No Work Yet
