Description of the Book:

The Natural Background Radiation Module computes the Earth’s natural upwelling spectral radiance (from 2 to 5 micrometers) by averaging over paths in an Earth-tangent cone with vertex at each selected altitude. The processes contributing to the radiance are emission from air, Earth’s surface, and clouds and reflection of solar radiation from Earth’s surface and clouds; attenuation is by molecules and aerosols. The Module integrates ROSCOE-IR models for atmosphere, atmospheric thermal emission, molecular transmittance, aerosols, clouds, Earth’s surface characterization and radiance, solar radiation, and upwelling natural radiation. The last 3 models are documented fully; other models (three of which were developed by other organizations) are documented mainly in terms of functions performed, inputs, and outputs. The user selects the modeled Earth’s surface from one of seven categories (with possibly an associated descriptor): Lambertian surface (and diffuse reflectance), wind- ruffled water (and wind speed), snow (and its age parameter), sand, soil, foliage, and urban material (and degree-of-urbanization parameter
