Remote Sensing of Water Vapor in the Infrared Atmospheric Measurement (mwr scaled sondes) Transition Frequencies (Pressure Shifts) Strengths Widths (Temperature Dependence) Shape: Voigt Continuum Definition: Continuum is that absorption with slow spectral dependence which, when added to the line by line absorption, provides agreement with measurement.

Summary Water Vapor Effectively no ground truth Reasonable consistency across the band NO evidence (yet) for -line shape other than Voigt -higher spectral content for the continuum Significant improvement in line parameters since IRS 2004 (MIPAS-EOS) BUT Spectroscopy is the current limitation on the accuracy of retrievals from space!
