The purpose of the present paper is to evaluate the bias introduced by the commonly used homogeneous plane-parallel cloud hypothesis in the computation of actinic fluxes, photolysis coefficients, and main tropospheric species concentrations. Accordingly, these quantities obtained for an inhomogeneous cloud field generated with a stochastic model are compared to their homogeneous plane-parallel equivalent. Results show that neglecting cloud inhomogeneities has a significant impact on actinic flux. For instance, the bias introduced by the homogeneous plane-parallel cloud hypothesis can reach more than 100% below the cloud leading to a comparable bias in photolysis coefficients and, in turn, creating an enhancement of the oxidizing capacity of the system.
