 Abstract: We have developed a regolith radiative transfer model (RRT) based on a frst-principles approach to regolith modeling that is essential for near-to-far infrared observations of grainy surfaces, and is readily confgured to answer fundamental questions about popular models with which all remote observations of all airless solar system bodies with granular surfaces are currently interpreted. Our model accounts for wavelength-size regolith particles which are closely packed and can be heterogeneous in composition and arbitrarily shaped. Here we present preliminary results showing the role of porosity on layer refectivity. © 2011 by the Author(s); licensee Accademia Peloritana dei Pericolanti, Messina, Italy.
