Paper Abstract

The MCScene code, a high fidelity model for full optical spectrum (UV to LWIR) spectral image simulation, will be discussed and its features illustrated with sample calculations. The MCScene simulation is based on a Direct Simulation Monte Carlo approach for modeling 3D atmospheric radiative transport, as well as spatially inhomogeneous surfaces including surface BRDF effects. The model includes treatment of land and ocean surfaces, 3D terrain, 3D surface objects, and effects of finite clouds with surface shadowing. This paper will review the more recent upgrades to the model including the development of an approach for incorporating direct and scattered thermal emission predictions into the MCScene simulations. Sample calculations presented in the paper include a full optical spectrum simulation from the visible to the LWIR for a desert scene under a broken cloud field. This scene was derived from an AVIRIS visible to SWIR spectral imaging data collect over the Virgin Mountains in Nevada. The data has been extrapolated to the thermal IR. Other calculations include complex 3D clouds over urban and rural terrain.
