The discussion centers on the search for atmospheric transmittance data specific to Venus, particularly in the C-band. A user suggests comparing the absorption spectrum of Earth's atmosphere to that of Venus to derive the transmittance information. However, the original poster clarifies their interest in obtaining a transmittance plot, also referred to as an opacity plot, rather than reflected spectrum data. Links to relevant resources, including a Venus spectra image from ESA and an example of Earth's atmospheric transmittance, are provided for further reference.
