Key Points

To formulate simple, physically grounded analytical parameterizations for vertical profiles of solar and infrared radiative fluxes within layer clouds.
Formulated analytical profile shapes for vertical solar and infrared radiative fluxes within a layer cloud overlying a partially reflective surface.
Derived governing parameters from bulk radiative properties and physics-based radiative transfer models.
Structured parameterizations using exponential functions of height, setting decay scales determined by cloud liquid water content.
Produced closed-form analytic formulations representing internal solar and infrared flux profiles without requiring complex numerical integration.
Demonstrated that vertical flux attenuation can be modeled using height-dependent exponential decays tied directly to liquid water distributions.
Established a generalizable framework adaptable to non-uniform cloud layers and broader numerical radiative transfer modeling.
