Validation of H₂O Continuum Absorption Models in the Wave Number Range 180-600 cm⁻¹ with Atmospheric Emitted Spectral Radiance Measured at the Antarctica Dome-C Site
We present the results concerning the analysis of a set of atmospheric emitted (down welling) spectral radiance observations in the spectral range 180 to 1100 cm −1 acquired at the Dome-C site in Antarctica during an extensive field campaign in 2011-2012. The work has been mainly focused on retrievi...
