Abstract
We present the implementation of dusty, radiation pressure-dominated photoionization models applicable to the narrow-line regions (NLRs) of active galactic nuclei, using the MAPPINGS III code. We give a grid of the predicted intensities of the most commonly used diagnostic spectral lines in the UV, optical, and IR, covering a wide range of density, metallicity, the power-law index characterizing the photoionizing source, and photoionization parameter, for use in the diagnosis of NLRs. We examine the temperature, density, and ionization structure of these models, investigating the effect of variation of these parameters in order to gain a better understanding of NLR clouds themselves.
