Environment representations are used in a variety of simulation-based training exercises and sensor performance studies in which standardized meteorological product suites must be realistic, time- and space-correlated and physically consistent. Here we focus on simulation of satellite imagery and virtual globe (VG) cloud layer visualizations from four-dimensional numerical weather prediction (NWP) model representations using physics-based radiative transfer modeling. Satellite imagery products are designed to closely mimic operational imagery from a number of sources, including characteristic background coloring, various file formats (NITF, PNG, GeoTIFF), and embedded tags (e.g., geospatial, time). The VG cloud layer visualizations are derived from the same core physics but are rescaled to better simulate the more subjective point-of-view of the human eye and to accommodate the uniform brightness typical of VG base imagery.
