Puntos clave

• This research aims to improve the detection of cloud vertical distribution characteristics through optimized spectral channel settings in satellite imaging.
• Optimized shortwave infrared channels (1.6, 2.13, 2.25 micrometers) were proposed for better cloud characteristic detection.
• Utilized differences in absorption properties of solid and liquid cloud particles to identify overlapping clouds.
• Integrated at least four shortwave infrared channels into a single satellite imaging system for accurate cloud parameter retrieval.
• The optimized spectral combination significantly reduced cloud characteristic inversion errors and improved cloud radiative effect estimates.
• Showed enhanced detection accuracy for overlapping clouds, including key parameters like cloud height and microphysical properties.
