Short summary
This work investigates the impact of the Earth's sphericity on geostationary satellite observations, particularly in the context of the operational estimation of aerosol and land surface properties from the Meteosat Third Generation-Imager's Flexible Combined Imager. We demonstrate that the plane-parallel approximation widely used in fast radiative transfer codes can introduce significant biases in certain situations, mainly depending on the observing geometry and wavelength.
